ORDERING SPARE PARTS
To ensure that you order the correct part from your SRE dealer please use the
following procedure.
ALWAYS QUOTE THE MACHINE AND SERIAL NUMBERS WHEN ORDERING.
Refer to the Parts Manuals front page/s, listing the machine assemblies. Select the
correct machine assembly number which is printed in the top left corner of the page
(starting with 8099_ _ 01), This machine number is listed above or can be taken
off the Powerblade identification plate.
Looking down the page, select the relevant sub assembly that your required part
falls within. Sub-assemblies start from 8090_ _ 01. Note the year or serial number
of the machine may determine a correct sub assembly if more than one is listed.
Continue through the manual and find the relevant sub assembly parts listing.
Again the number will be printed in the top left corner; the sub-assemblies are in
numerical order.
Having found the correct parts list, you will find the corresponding drawing by either
looking at the facing page or progressing through the manual to the next drawing.
The drawings indicate the components by item numbers, which you will find, are
repeated in the left-hand side of your parts listing, and therefore referring to the
correct part.

manual and the manufacturer's maintenance and servicing requirements.
2.15
NO LIABILITY FOR CONSEQUENTIAL DAMAGE
Even though your Shelbourne Reynolds Powerblade trimmer has been manufactured
with the utmost care and you are using it properly, fluctuations and interruptions in
operation rate may still occur.
It is the duty of the operator/user to ensure that foreign objects, e.g. stones, metal
objects etc. are not allowed to enter the cutting head and are therefore not ejected
dangerously. Failure to observe this may result in damage to the Powerblade trimmer
and/or injury to the operator/user and members of the public.
Any claims for damages not directly incurred by the Powerblade trimmer cannot be
accepted. By the same token, Shelbourne Reynolds cannot be held liable for any
consequential damage resulting from incorrect use of the machine.

SECTION 3:
3.1
SPECIFICATION AND DESCRIPTION
DESCRIPTION
The machine consists of a cutting head, which is positioned by a number of
articulating booms, mounted to a frame, which carries the relevant control and
drive systems.
A double-skinned head shell (A) with a rotor (B) is fitted with a choice of cutting flails.
This is driven by a hydraulic motor (C) mounted within the envelope of the head. An
adjustable nose (D) is fitted to minimise the effect of any thrown objects. A hydraulic
cylinder (E) rotates the head about the outer boom arm (F). The outer boom can be
fixed, variable forward reach (VFR) and telescopic. A hydraulic cylinder (G) varies the
reach of the arms in an almost straight line due to the effect of the parallel arm (H). The
first boom (I) is fitted with a pad (J) to close the booms together for safe, controlled,
transportation. A hydraulic cylinder (K) rotates the rocker (L) and thus lifts and lowers
the head and booms. A hydraulic cylinder (M) rotates the pillar (N) to give forward and
rearward slew and a safety breakback action. Gearboxes, pumps and controls (O) use
a fully independent (twin pump) oil supply from the large s hydraulic tank (P) to operate
the aforementioned cylinders and motor, which are protected from contamination by a
pressure and return filter (Q). A guard (R) covers and helps to protect the hydraulic
components.
2.7
INTENDED USE
The machine is intended to be used on typical farms and highways for annual or
biennial cutting of hedges and for cutting grass and weeds on verges and banks.
The fine cutti
ng action of the flails reduces theFneed for clearing up after
H cutting (though may not
remove it altogether) and (unless the growth is particularly luxuriant) leaves no swath
I
which might kill underlying grass.

Higher powered hydraulic drive system is also an available option delivering more
power to the cutting head. This requires the tractor PTO to be run at 800 rpm.
Narrow lane bracket option is available for all HD700 trimmers.
35
Highways kit option includes four piece chevron kit, magnetic arrow, two LED strobe
lamps and two florescent boom transfer. This is recommended if working on public
highways.
Debris blower kit is available to be fitted at the rear of the Powerblade.
Active electronic float (AEF): AEF uses the hydraulic roller cylinder to sense the
amount of pressure the cutting head is applying to the ground. As the pressure
increases or decreases onto the roller the booms will be lifted up or down as
appropriate. This allows the head to follow the contours of the ground without the
operator needing to adjust the Lift or Lower function.
36
SECTION 4:
HANDLING AND TRANSPORTATION
Refer to section 2 for safety procedures.
To prevent damage to the trimmer the machine should only be moved by one of the
following methods.
4.1
UNLOADING/LOADING
Refer to section 2.3 for accident prevention before starting.
1. Use the forklift tine holes that are incorporated into the design of the Powerblade
trimmer. Earlier build HD700 machines use the bolt on type brackets. Later build
machines use the forklift shoes which have been incorporated into the design of
the Powerblade stand.

37
Ensure that the tines go through both slots in the front and back plates.
Insert the tines as far as they can go, to get the trimmer as close to the forklift as
possible.
It is recommended that the head is parked as close to the rear of the trimmer to lessen
overhanging weight and not exceed forklifts capacity.
Take care not to insert the tines through so far that the tips contact with the cutting
head. This may cause damage to the cutting head or even cause the tines to slip
during transportation of the Powerblade.
2. By slinging and using an overhead lifting device, generally during loading and
unloading. Attach slings or chains to the designated lifting / sling points.
Sling point on inner boom.
Sling point on main
pivot rocker.
Ensure the lift cylinder taps are closed before lifting commences and the slew locking
device is fitted (see section 7.1).
4.2
TRANSPORTATION
Refer to section 2.9 for accident prevention when leaving the machine.
Refer to section 2.11 for accident prevention when taking on public roads.
For transporting attached to a tractor, see section 7 for more detail and correct
procedure’s to follow.
38
When transporting the Powerblade ensure:
1. Ensure that the two taps on the ports on the lift cylinder are closed, handles are
positioned 90 degrees to fittings, to lock cylinder movement (see section 7).
2. Ensure the slew locking device is also fitted to lock of any slew movement (see
section 7).
3. Ensure Forklift has suitable capacity to lift trimmer.
4. Ensure all nuts and bolts are tight and that the trimmer stands locking pin is in its
locked position for both stands before attempting to move the Powerblade.
5. Ensure when leaving the Powerblade in a new location, it’s on a firm and level
site and the cutting head is supported directly underneath the pivot shoe.

SECTION 5:
PREPARATION FOR USE
Refer to section 2 for safety procedures.
Use the dealer pre-delivery/installation check and warranty registration form positioned
at the front of this manual to check through the Powerblade trimmer. This section will
help to expand on the pre-delivery/installation.
5.1
CHOICE OF TRACTOR
Refer to section 2.3 for accident prevention before starting.
Refer to Section 3 for the recommended weight of tractor and the typical horsepower
requirement for the various machine configurations.
Before attaching the Powerblade trimmer it is important to ensure the tractor is suitable
for the trimmer.
It may be required to either weight or ballast the tractor to obtain suitable
stability. This should be done to the tractor manufactures recommendations.
The tractor size and weight should be substantial enough so that when the Powerblade
trimmer is at its full extent in all conditions, the tractor remains completely stable and
with all four wheels in full contact of the ground. Either in work or on the public highway
a minimum of at least 15% of the total vehicle weight of the tractor and trimmer should
be carried on the front axle. At least 20% of the rear axle weight should be carried on
the opposite wheel to the cutting head.
Ensure tractor axle weights and tyre ratings are not exceeded.
Ensure the combination of the tractor and trimmer does not exceed the gross vehicle
weight.
Weights can be measured by driving the tractor and trimmer combination onto a weigh
bridge ensuring a full tank of diesel, operator in position, any necessary front and wheel
weights added prior to weighing.
Note: Not all manufacturer tractors of similar sizes have the same carrying / axle
capacities, if in doubt check with your dealer.
Tractor wheels should be set as wide as required to obtain maximum sideways
stability in all working conditions. However if a tractor width is between 2.55 – 3
meters speeds of more than 32 KPH (20 MPH) must not be exceeded when on
the public highway
41
5.2
PREPARATION OF THE POWERBLADE BEFORE ATTACHMENT
Refer to section 2.3 for accident prevention before starting.
The Powerblade will be delivered to the dealer fully assembled, except for the stabiliser
mounting system and final hydraulic, electrical and PTO connections.
Remove the front and rear forklift brackets (pre 2013 models only).
Powerblade trimmer checks:
 Check in general that nuts & bolts are tight.
 Ensure that all safety guards, decals are fitted and legible.
 Check hydraulic oil level (see section 8).
 Check gearbox oil level (see section 8).
 Lubricate all accessible grease points (see section 8).
Powerblade trimmer cutting head checks:
 Check all flails are intact and the flail bolts are tightened correctly (see section 8).
 Check drive belts are tensioned correctly (see section 8).
 Check that both safety curtains are fully intact.
 Check that the head nose can be adjusted fully up or down (see section 7).
 Ensure there are no foreign objects inside the head shell.
5.3
PREPARATION OF THE TRACTOR BEFORE ATTACHMENT
Refer to section 2.3 for accident prevention before starting.
The Powerblade trimmer is suitable for a Category 2 tractor linkage and in most
instances Category 3. Shelbourne Reynolds Engineering Ltd recommends that this be
of good quality and in good condition. Check the condition of any quick release ball
ends carefully, as they will be subjected to upward forces. Check chains and stabilisers
should also be in good condition when using the stabilising kit, as they will be relied
upon to assist it in its function.

Ensure the tractor drop arms are of equal length ensuring they are kept at the minimum
length required while still being able to hitch on the trimmer. Ensure the pin which
connects the drop arm to the lift arm is positioned into the fixed rather than the float
position (please refer to the tractor operators manual).
The cab safety guards should now be fitted. These must protect any screen, which will
be in direct line of sight from the flail head in its various positions. This will include all
the side windows on the work side, the rear screen and in some cases the windscreen.
Guards can be purchased from Shelbourne Reynolds Engineering. Note it is essential
that the cab is fitted with safety glass and that the relevant windows and doors remain
closed when the Powerblade trimmer is in use.
Ensure all tractor mesh/polycarbonate guards are suitable for the job, undamaged and
well maintained.
Ensure to have read the tractor operators manual thoroughly and practise using the
tractor controls (especially those relating to the 3 point linkage) prior to starting to
couple the machine.
If the Powerblade trimmer is specified with the axle frame option the tractor is required
to be fitted with axle brackets. These may already be on the tractor so in this case
compatibility should be checked with you dealer as different manufactures may supply
different types of axle brackets which may only be suited for their brand of trimmer. If
fitting another manufactures axle brackets ensure to follow their instructions on how to
fit the axle brackets to the tractor.
Axle brackets to suit Shelbourne Reynolds Powerblade should be set at either 1000 or
1100 mm between centres. In fitting these brackets it may be required for the removal
of the check chain bracket which in turn should be incorporated into the design of the
axle bracket.

how to fit the axle brackets to specific tractors.
5.4
FITMENT OF 3 POINT LINKAGE STABILISER TO THE POWERBLADE
Refer to section 2.4 for accident prevention when coupling and uncoupling to the
tractor.
A stabilising system may be supplied to help to limit the rolling movement of the
machine relative to the tractor.
See parts manual MAN – 10101, Kit-08076 for more details.
Ensure the machine is on a firm level site with plenty of room to conduct the fitting
operation.

Note: Throughout this section item numbers mentioned are related to the above
drawing KIT-08076.
1. Connect both items 1 onto the trimmer using nuts and bolts (item 2, 3 & 4). Keep
the nuts and bolts loose at this stage. Allow both items 1 to rest onto the ground.
2. Ensuring the right way round (three top link holes facing towards the trimmer
frame) proceed to slide item 7 onto both of item 1. Check item 7 is free to slide
fully up and down the two shafts

6. Keep unused components for when attaching the Powerblade to the tractor.
5.5
FITMENT OF THE AXLE FRAME STABILISER TO THE POWERBLADE
Refer to section 2.4 for accident prevention when coupling and uncoupling to the
tractor.
As an option the machine can be supplied with stabiliser axle mounting kit and brackets
to enable it to be latched to the tractor’s rear axle. This is strongly recommended for
45
telescopic machines, all machines equipped with a 1.5m head and all machine with
more than 6 metre reach. The system will not only reduce the stress on the tractor
linkage but also makes the actual response of the head to the controls more
predictable.
See parts manual MAN – 10101, Kit-08015 for more details.
Ensure the machine is on a firm level site with plenty of room to conduct the fitting
operation.
Fitment of the axle frame stabiliser kit to the Powerblade trimmer.
Note: Throughout this section item numbers mentioned are related to the above
drawing KIT-08015.
1. The axle frame stabiliser which connects to the tractor can be set at two
different widths. Both Pin arms item 2 can be flipped over to give either 1000
or 1100 mm depending on which width the axle brackets attached onto the
tractor axle have been set.

2. Once the correct width has been identified it’s important to work out the axle
frames overall length required which will ultimately determine the distance
between Powerblade and the tractor. Multiple holes in both item 1 and item 2
allow 70mm increments of the overall length of the axle frame assembly. The
Powerblade should be as close as physically and practically possible to the
rear of the tractor whilst maintaining sufficient gap that in all positions the
Powerblade DOES NOT contact the tractor (e.g. tyre, mud guard etc…).

3. It’s also possible to reduce the overall axle frame size further if required. This
is done by cutting material off the hitch sub frame at the specified points.
Cut off at marked
notches 70mm &
140mm from edge
each end
4. With the correct width and overall length identified assemble items 2 together
with item 1 using items 3, 4, 5 and 6.
5. Fit the drop links items 12 using items 13, 14 and 15 into the middle of the
three holes. The other two holes maybe required if the tractor drop arm
cannot be connected due to the angle. Check the drop links fit the tractor
drop arms as these are tractors specific (When ordering KIT-08015 supply
tractor make and model).
6. Using appropriate lifting equipment connect the assembled axle frame to the
Powerblade frame using pins 7 & 8.
7. Then connect the top link (item 10) into position ‘B’ between the trimmer
main frame and the axle frame assembly. Using fixings 8, 9 and 11.
48
8. The axle frame is now assembled and ready for the tractor to be attached.
It’s also possible to attach the axle frame assembly to the tractor before then
attaching to the Powerblade.

removed totally or secured away.
10. Follow the previous procedure up until step 5. Then using suitable lifting
equipment connect the axle frame into the axle brackets as picture above.
11. Connect the drop links item 12 to the drop arms from the tractor. Ensure drop
arms are equal length prior to connecting. Ensure the drop arm connecting
pin is positioned in the fixed, not float, position (refer to tractor operators
manual).
5.6
ATTACHMENT – 3 POINT LINKAGE STABILISER, TRACTOR TO
POWERBLADE
Refer to section 2.4 for accident prevention when coupling and uncoupling to the
tractor.
Throughout this section item numbers mentioned are related to the below drawing of
KIT-08076. See parts manual MAN – 10101, Kit-08076 for more details.
49
1. Identify if the tractor has lift arms with fixed ball ends or has a quick release ball
end style. For Lift arms with the fixed ball ends prepare the pin, lynch pin and
spacers
2. Identify which hole on the trimmer frame which will best suit the tractor and
machine combination. The machine should be as close as physically and
practically possible to the rear of the tractor whilst maintaining sufficient gap that
in all positions the machine DOES NOT contact the tractor (e.g. tyre, mud guard
etc…), as shown previously. Positioning the connection pin into the front hole
will provide a greater gap between the tractor and machine. Positioning the
connection pin into the rear hole will provide a closer gap between the tractor
and machine.
Front hole
Rear hole
Note: Some tractor lift arms may not be compatible to use the rear hole if the crank
within the lift arm is too great.
3. For lift arms of the quick release ball end type fit the tractor balls to both sides of
trimmer frame and add spacers for sideways movement as shown below.
Tractor Ball
Lynch pin
Pin
Spacer 16mm
Spacer 13mm
4. The tractor should then be carefully reversed slowly towards the machine, to
attach the tractor lift arms onto the trimmer frame. Allowing either fixed ball end
lift arms to enter the frames clevis and pin, to correctly align or quick release lift
arms to align and travel under balls. Raise quick release arms slightly until they
lock onto balls. Perform a ‘Safe stop’ procedure before dismounting from the
tractor. Ensure the lift arms are locked onto balls, or pins can be inserted
through fixed ends.
5. Remove the tractor top link from the tractor but ensure to keep the top link pin
and lynch pin close to hand.
50
6. Support the weight of the 3 point yoke. Remove the Rocker from between the 3
point yoke and the trimmer frame. Re-position the rocker into the front of the 3
point yoke using pin, lynch pin items 9 and 6. The rocker has two positions and
can be turned over to bring the frame back or up to avoid parts of the tractor.

Note: A longer rocker is also available to order from SRE parts part number: 801361 01
if the tractor is not compatible with the standard fitment.
7. Check the outside diameter of the tractor top link pin in relation to the internal
rocker diameter to ensure a good sliding fit. Use spacers provided items 10 and
15 to reduce the amount of gap between the outside diameter of the top link pin
to the internal diameter of the rocker.
8. Connect the rocker and 3 point yoke assembly into the top link clevis of the
tractor.

10. Ensure the tractor check chains are free to float at this stage.
11. Ensure pins items 5 are removed then slowly raise the 3 point linkage of the
tractor to the required height for carrying the machine. Ideally the tractor PTO
and the gearbox shaft should be at the same level. When lifting the 3 point
shafts (items 1) will be sliding through the 3 point yoke (item 7).
12. Lengthen or shorten the top link so that on level ground the trimmer frame is
vertical. This will also affect the angle of the cutting head in relation to the
ground.
13. Lift or lower the tractor 3 point linkage to align the holes between the 3 point
yoke and the 3 point shaft. Insert pin (item 5) and secure using the lynch pin as
shown below. Ensure as much overlap as possible between the 3 point yoke
and 3 point shafts. With pins (item 5) installed lower the 3 point linkage to take
the trimmer weight onto the 3 point stabiliser.
Pin items 5
52
Serious damage may occur if the tractor 3 point linkage is raised without
removing 3 point linkage locking pins (item 5).
14. Fully tighten the nuts and bolts items 2, 3 and 4 holding the 3 point shafts.
15. Lock the tractor check chains with the machine positioned centrally to the tractor
ensuring to adjust them so that there is no sideways sway.
16. Then shorten the tractor left hand drop arm or lengthen the right hand drop arm
as much as possible so that the Powerblade is parallel to the tractor axle. This
will remove the accumulation of clearances within the tractor rear linkage once
the Powerblade is boomed out to the side. This would be the opposite way
round on right hand build trimmers.
17. Point 15 and 16 should be repeated once the trimmer is fully operational. In
some cases it’s also required to place the head horizontal to the ground, close to
the tractor tyre in the work position power the booms into the ground. This may
then allow further adjustment to the tractor check chains and drop arms if
required.
18. Correct adjustment has been reached when with the booms in the work position
the machine remains parallel to the rear axle of the tractor. Take tyre squash
into account when viewing this.
53
Ensure the check chains are tight.
This procedure should only be carried out by a single person. Extra care must be
taken throughout the procedure as high risk is involved.
Points 15, to 18 should be checked after 4 hours use, then checked and as
repeated required peordically thereafter.
Stability between the tractor and machine in all positions is of the upper most
importance to ensure the safety to the operator and any other person or persons who
may come into the contact area. If the stability of the unit is questionable then any
operation should be ceased with immediate effect. Contact you dealer immediately.
5.7
ATTACHMENT – AXLE FRAME STABILISER, TRACTOR TO POWERBLADE
Refer to section 2.4 for accident prevention when coupling and uncoupling to the
tractor.
See parts manual MAN – 10101, Kit-08015 for more details.
1. Remove the drop arm pin connecting the tractor’s drop arms to the lift arms. Lift
arms should ideally be removed or otherwise secured so that they cause no
obstruction.
2. The tractor should now be carefully reversed slowly until it is in, approximately
the intended final position relative to the machine. Ensure to keep the tractor
squarely aligned to the trimmer assembly. If still attached the lower link arms
may need to be repositioned to clear. Perform a ‘Safe stop’ procedure before
dismounting from the tractor to check that the pin arms (item 2) are in line with
the axle brackets attached to the rear axle of the tractor.
54
Ensure clearance maintained between the tractor and machine.
3. Connect the drop arms of the tractor into the drop links (item 12) attached to the
axle frame assembly using the drop arm pin supplied with the tractor.
Drop arms

(item 12)
4. Once the tractor axle brackets and the axle frame assembly are aligned connect
the axle frame into the axle brackets either by shortening the top link (item 10)
set in pos ‘B’ or slowly and carefully raising the tractor’s drop arms. The subframe will rise at its front so that the pin arms engage in the latches. Raise
slowly and carefully until these are fully home and secure (Note – Do not lift the
trimmer off the ground, just raise the axle frame. Fit relevant retaining pins and
clips (see axle bracket instructions). There is no need to tighten the check
chains of the tractor with this system.
Tractor axle

5. Once frame is connected to the axle brackets lower drop links until top link (is
POS ‘B’) becomes unloaded.
6. Remove the top link (item 10) from POS ‘B’ and move into POS ‘A’ connecting
between the trimmer frame and the tractor top link clevis. If the top link supplied
with tractor can be shortened enough to fit between the trimmer and tractor
(POS ‘A’) then it’s recommended this is used rather than the top link (item 10).
Note that the top link has a Cat 2 and a Cat 3 end with a spacer. Together these
allow connection to Cat 2 or Cat 3 tractors. Ensure that the correct pins are used
and that lynch pins are used throughout and are secure.
55
Ensure not to leave the top link in an overextended position between the
machine and tractor
7. The machine should then be slowly and carefully raised to a height that brings
the tractor’s PTO shaft and the gearbox input shaft to the same approximate
height, whilst checking at all times that if the lift arms are still attached they are
fouling nothing.
8. To prevent undue stress on the top link clevis of the tractor, the system uses the
tractor’s drop arms to carry the weight of the machine. Some tractors,
particularly of high hours, may be prone to their link arms sinking when switched
off.
9. If the axle frame has already been fitted to the tractor (See section 5.5 items 8, 9
and 10) then slowly reverse the tractor until the holes on the axle frame become
in line with the required hole on the trimmer main frame.
10. Fit the pins and lynch pins between the axle frame and the Powerblade frame
using pins items 7 & 8.
11. Complete steps 5 & 6 as described above.
12. Check all components are fully tightened and all the fasteners in place.
5.8
ADJUSTING AND CONNECTING THE PTO DRIVE SHAFT
Refer to section 2 – Accident prevention when using the PTO shaft
The correct length of the PTO drive shaft may vary depending on the tractor in use. It
may be necessary to shorten the PTO drive shaft.
The length adjustment is to be carried out as follows:
56
To adjust the lengths hold the
half shafts next to each other
in the shortest working position
and mark them 40mm as shown.
Shorten the inner and outer
guard tubes equally.
Shorten the inner and outer
Sliding profiles by the same
length as the guard tubes.
Remove all sharp edges and
burrs, grease the sliding .
Profile tubes
Grease the profile tubes before they are assembled, as they will otherwise be
exposed to high friction forces.
Ensure the inner and outer PTO shafts are overlapped by at least 150mm when
the tractor and machine are straight. Damage to the shaft and injury may result.
Fit the PTO shaft ensuring to:
Connect the pin type yoke end to the Powerblade trimmer.
Connect the pull release yoke end to the tractor.
With the PTO connected but with its drive disengaged, ensure that the machine can be
lowered to its standing height without the PTO fouling on any part of the tractor or
machine, the link arms (if attached) fouling in any way or the electrical cables being
stretched.
Having connected the PTO shaft, ensure the guard anti-rotation chains are clipped to
the chassis and tractor at both ends. The PTO shaft should turn clockwise ONLY.
Make sure the tractors correct PTO speed is selected at all times.
57
5.9
CONNECTING THE CONTROLS
Controls should be mounted near-to-hand on the LH side of the tractor. Ideally the
controls should move with the seat so that if the terrain is bumpy the seat and controls
will move up and down together.
All controls are supplied attached to a bracket. The supplied bracket is intended to
replace the armrest on Grammar seats (this make is fitted to most tractors). Although it
may be necessary to find an alternative way of mounting the controls if your tractor
does not have a compatible seat (Note; consult your dealer before drilling the cab side,
as there is a risk this could weaken the structure or damage underlying parts).
A 12 volt power supply is required for the electrical controls and oil cooler. These must
be connected, via a suitable fuse. The power supply must not come from the cigarette
lighter, three pin connector or trailer 7 pin socket; due to the electric controls having a
high current draw. Low voltage will cause the system to function erratically. Therefore
we recommend wiring directly to the tractor battery to guarantee system operation, with
the supplied power lead, fuse and connectors.
Erratic operation or serious damage to the system can result if these instructions
are not followed.
Beware of fire, sparks or electric shocks during fitment of power supply.

Route and secure the power lead into the tractor cab, terminating close to the controls
armrest. Using the two 7 pin connector ends connect the machine end wiring loom to
the joystick control box by joining the screw connectors together. Then connect the
power supply, using the two 4 pin screw connectors.
Check that the emergency stop button is functioning correctly (see section 6).

FINAL ATTACHMENT AND RUN UP
Refer to section 2.7 for accident prevention when operating.
Attach the lighting board 7 pin plug and the hydraulic roller hoses to the tractors double
acting spool if optionally fitted.
All HD Powerblade trimmers have fully independent hydraulics as standard.
The parking stands can now be swung up from their ‘parked’ to their ‘work’ positions.
Parking stands in fully down
position required when
machine is being parked
Parking stands in work

59
Parking stand on the
boom side has third
position required if
operating close to the
machine and tractor.
Start the tractor at low to medium revs, engage the PTO to allow the oil to circulate for
about 10 minutes without operating any other control valves. This will make sure that
the oil is thoroughly filtered by passing it through the filters but the minimum of other
components.
Open the taps on the lift cylinder to allow it to move (tap handles will now be in
line with the oil flow). Move the slew locking device to storage position. See
section 7 for instruction.
Having first read and understood the information on the controls (Section 6) again set
the tractor speed to a slow to moderate level. Now carefully operate the control buttons
and/or joystick, and ensure that all the movements are functioning correctly; be ready
at all times to cancel the action, should it be incorrect . Move all the cylinders to their
extremes to expel any air.
Ensure head does not hit tractor cab or wheels
Place the flail head just above the ground ensuring flails will be clear. Now start the
rotor. This will require moderate revs to avoid stalling-out the tractor, but full revs
should not be used. Adjust the revs to give approximately 350rpm at the PTO and run
the rotor for about 3-4 minutes. Stop the rotor, allow time to run down. Re-start rotor
running in opposite direction and again run for 3 – 4 minutes.
Check all hose runs to ensure that they are not pinching or chafing. Now check the oil
level in the tank and top up if necessary.
5.11
REMOVAL – TRIMMER WITH 3-POINT LINKAGE ASSEMBLY
Refer to section 2.9 for accident prevention when leaving the machine.
1. Select a firm and level site to park the machine.
2. Bring the head to a horizontal position approx. 1m from the wheel and 1m from the
ground. If applicable close the telescopic cylinder or straighten the VFR arms.
Ensure the roller is positioned in its upper most position (bolt up type or hydraulic).

REATTACHING THE MACHINE
Reattaching follows the same sequence as in the initial attachment methods. It will not
be necessary to adjust the length and width of the sub-frame unit, or the PTO shaft
length unless there has been a change of tractor. Any cab screens that have been
removed must be refitted. Unless the hydraulic circuit has been disturbed it will not be
necessary to follow a running-up procedure, though the system should always be run
slowly until the oil begins to warm up.

Lift & Reach: By moving the joystick to left and right the reach cylinder is actuated in
the relevant direction; moving it back/towards and forwards/away from the operator
gives lift and lower respectively. These actions are proportional; that is small joystick
displacements give slow cylinder movements and large displacements give faster
cylinder movements. Shelbourne Reynolds Ltd or a Shelbourne Reynolds approved
dealer will set-up the controls to the operators liking when the machine is delivered.

HD700 ELECTRIC PROPORTIONAL CONTROLS - OPTIONS
Hydraulic roller: Hydraulic roller uses the tractors double acting spool lever to move
the roller up or down (see tractor manual for spool operation). This allows the operator
to adjust the roller position without leaving the tractor cab. The roller is able to be
positioned in any position within the stroke of the cylinder. However see section 7 for
best position depending on the task being undertaken.
73
Narrow lane bracket: This uses the same hoses that control the hydraulic roller from
the tractor spool. A directional control valve is positioned on the head allowing oil to be
diverted between either the hydraulic roller or the narrow lane bracket. The control
lever can be moved between two positions.
Only operate directional control valve when the narrow lane bracket is in its
fully closed state. High risk of crushing.

Active Electronic Float (AEF): AEF uses the hydraulic roller cylinder to sense the
amount of pressure the cutting head is applying to the ground. As the pressure
increases or decreases onto the roller the booms will be lifted up or lowered down as
appropriate. This allows the head to follow the contours of the ground without the
operator needing to adjust the Lift or Lower function.
74
The HD700 can be changed into the AEF mode by toggling a setting within the control
box (See section 6.3).
Once the control box has been switched into AEF mode the control box display will be
changed to read as below.

Operation of Active Electronic Float:
1. Position the Powerblade arms in the work position at the side of the machine,
with the head just above the ground.
2. Extend the hydraulic roller down to the required cut length using the tractor
spool (see section 7). Allow the tractor spool to return to neutral. Ensure the last
movement of the cylinder is a downwards movement of the roller. Do not use the
system with the cylinder positioned at its full stroke as this may affect the
systems performance. Check no person or objects are within the machine
working area.
75
3. Press and hold the lift float button for one second to engage the AEF. The head
float will also be automatically engaged when pressing the lift float button. Head
float maybe turned OFF by pressing the head float button once. A solid LED
light will indicate if the head float is ON. Both lift and head float will be turned
OFF by pressing the lift float button once.

8. When in AEF and the joystick is pulled back between 0-50% of the joystick
movement the ‘HOLD’ feature is activated. This is used to hold the cutting head
in its position to stop the cutting head dropping into ditches/potholes.
9. When in ‘AEF’ and the joystick is pulled back between 50-100% of the joystick
movement the ‘OVERRIDE’ function is activated. At 50% joystick movement the
lift operates at its slowest speed. 100% joystick movement the fastest lift speed
is reached.
10. Once the joystick is released from ‘HOLD’ or ‘OVERRIDE’ the cutting head
automatically lowers to contact the ground, with the AEF operating again.
The amount of lift up joystick movement allocated to the ‘HOLD’ feature can be
changed from 50% down to 1% depending on the operator’s preference. This can be
changed within the AEF control settings in section 6.3.

MOVING FROM TRANSPORT TO WORK POSITION
See section 2.7 for accident prevention when operating.


For 3 point linkage machines lower the tractor 3 point linkage so that the weight
of the machine is carried by the stabiliser system. For axle mounted machines
this is not required.
Ensure the slew locking device has been removed, placed into its storage
position and taps on the lift cylinder moved from there transport to their work
position.

7.2
STARTING THE ROTOR
See section 2.7 for accident prevention when operating.
With the tractor engine revs low, the PTO running and the head positioned as before.
Check that all observers are clear of the Powerblade trimmer and tractor. Warn
bystanders by sounding the horn of the tractor several times. Ensure your visibility is
kept clear at all times. Engage the cutting head rotor drive button. Once rotor is running
slowly raise the engine revs to the correct speed; 540 or 800 rpm for grass cutting, 450
or 660 rpm approx. for hedgecutting.
7.3
STOPPING THE ROTOR
See section 2.7 for accident prevention when operating.
The rotor can be disengaged with the PTO running at working revs, because of the
design of the motor control valves. However it is good practice to reduce the engine
speed first.
7.4
TRANSPORTING WITH THE TRACTOR
See section 2.11 for accident prevention when taking on public roads
1. With the rotor stopped as above, bring the head to a horizontal position approx.
1m (3’) from the wheel and 1m from the ground. If applicable close the
telescopic cylinder or straighten the VFR cylinder.
2. Use the slew cylinder to rotate the arms fully back, and then position the cutting
head with the flail facing the operator and the top of the cutting head backwards
towards the following traffic.
85
3. The reach cylinder can now be fully closed bringing the outer booms onto the
bump stop on the inner boom.
4. The pad above the top link, the rocker bump stop should be adjusted to suit your
tractor so that there is at least a 300mm gap between the booms and the rear of
the tractor cab, otherwise the boom members will be subjected to considerable
stress should the head/outer boom bounce. Even then the transportation speed
must be reduced on uneven surfaces.
5. Taking care that the booms do not foul the cab top, extend the lift cylinder to
bring the rocker to rest gently onto the bump stop. Disengage the PTO.

6. On 3 point linkage mounted machines we recommend that the linkage is
carefully raised by a small amount for transportation – so that the weight of the
machine is carried on the lower link arms of the tractor rather than its top link
anchor point. As the linkage is raised you will find that the nose part can rotate
by a small amount within the stabiliser frame. Once there is a small gap between
86
the front of the stabiliser frame and the recess in the nose part the weight is
being carried on the link arms.
Care must be taken that the positioning of this machine relative to the tractor does
not cause the dimensions of the combination (maximum width 2.55mt) to make it
ineligible to travel on the public highway.
The booms should be arranged so that the head is as close as is practicable to the
rear of the tractor (while leaving a safe distance from boom arms to cab top).
7. The lift cylinder taps must be turned off during transit.
8. Even though the slew cylinder has PO check valves which locks the cylinder
hydraulically a mechanical slew locking device should put in place during all
transportation on the public highways.

9. Disengage the PTO and turn the control box power off.
87
HD trimmers come with road lights as Standard so these should be connected when on
the highway.
Ensure head is not obscuring lights visibility.
7.5
WORKING ON THE HIGHWAY
See section 2.11 for accident prevention when taking on public roads
When intending to operate on the highway consult the local Highways Department
regarding notifications and approval, as rules and regulations will vary from area to
area and with the class of highway. It is likely that, at least, warning signs will need to
be placed at both ends of the work area. A flashing beacon and dipped headlights will
assist in drawing the attention of other road users to the tractor and machine.
7.6
FLAIL HEAD ADJUSTMENTS
See section 2.10 for accident prevention when servicing / adjusting the machine.
Always lower the cutting head into the work gently.
The rear roller can be placed in one of 6 height settings. For hedge work the roller can
be raised so that it is 25mm (1”) above the cut height. Obviously this is totally
unsuitable for verge work; for which the remaining positions are provided. These will
leave the vegetation at a height of 20, 40, 60, 80 or 100mm. Position the head on its
side in contact with the ground then it is necessary to loosen the pivot bolt in the
bracket on each side and then loosen and remove the other bolt. The bracket can then
be swung to the desired position and the bolts replaced and tightened.
Never remove the rear roller completely. It helps to control the flow of cut
material out of the head and helps to shield the flails from obstructions.
The nose is adjustable into one of six positions. To reduce the danger of debris being
thrown out of the front of the head the nose must be set in its lowest position for verge
work, and as low as is practical for hedge cutting.
Nose fully closed
position
Rear roller fully
up position
88
Nose fully open
position
Rear roller fully

Never remove the nose completely. Always keep the front and rear curtains in
good condition.
The rotor control can be engaged to up cut or down cut. Downwards cutting puts
greater strain and shocks on the rotor and drive components and leaves a ragged
finish. If intending to downward cut, ensure that the flails fitted are suitable for this task,
i.e. bi directional.
Never reverse the direction of cut while the rotor is still turning, wait for it to stop.
7.7
HYDRAULIC ADJUSTABLE ROLLER
See section 2.7 for accident prevention when operating.
Hydraulic adjustable roller is an optional extra on all models. One hydraulic cylinder is
mounted on the head shell and can infinitely vary the position of the roller throughout
the range possible for the standard bolted version. The cylinder is actuated by a
double-acting hydraulic spool service from the tractor.
Ensure that both hoses are correctly connected before adjusting the roller.
Damaging high oil pressures can be generated if actuated with one hose
disconnected.
7.8
WIRE CUTTER
See section 2.7 for accident prevention when operating.
See section 2.8 for accident prevention when removing a foreign
object/blockage.
The wire cutter is an important safety feature. It is located on the underside of the
adjustable part of the nose. Its function is to, as far as possible cut longer lengths of
wire into shorter, safe lengths. However, the dangers that wire presents means that the
operator must ensure that there is no wire in the area to be cut and that there is no wire
wrapped around the rotor. Follow below section removing foreign objects or blockage
from the machine if needing to remove wire from the cutting head.
89
Never interfere with, or modify the wire cutter.
7.9
VERGE CUTTING
See section 2.7 for accident prevention when operating.
All HD700 trimmer models have head float and lift float as standard.
Head float works using the centrally-placed head which can then roll naturally with the
ground contours, easing the operator’s task. The operator can override this manually
by operating the joystick head angle service.
Lift float facility is, operated by manually charging an accumulator. This reduces the
load on the roller; thereby lowering the breakback forces and saves the operator from
having to constantly alter the cutting height. The operator will be required to operate
the lift cylinder up or down to always ensure the cutting head rear roller is in contact
with ground.
Never attempt to cut hedges with the Arm float engaged.
Never leave the Arm float engaged when folding for transport.
As the head is brought inwards the pressure in the lift cylinder needed to support it is
reduced. If the lift float is left engaged the excess pressure can cause it to lift too much
and/or unexpectedly.
Going too fast along the ground will tend to leave a ragged finish.
For machines fitted with hydraulic roller it’s recommended to bolt the roller up when
verge mowing for any long periods of time. This will serve to increase the life span of
the wearing components within the roller linkage. Note: active electronic float will not
work if being bolted up.
HD700 Powerblade trimmers also have an active electronic float option. This allows the
head to follow the ground by the hydraulic roller sensing the different contours of the
ground (see section 6) and the lift cylinder being operated automatically for the
operator.
7.10
HEDGE SHAPE AND CUTTING SEQUENCE
See section 2.7 for accident prevention when operating.
The shape of the hedge is likely to be influenced by regional practices and what is
required of the hedge. An ‘A’ shape is usually recommended as the wide base
encourages wildlife and favours new growth. It is considered that, though neatest, a
rectangular hedge favours top growth, which can cause the base to die back. Heavy
falls of snow can then damage it. Where heavy snow is likely a sloping top is often
used; the extra light reaching the base keeps the base strong and also helps to throw
off deep accumulations of snow.
90
If the hedge bounds a road it is suggested that the siding cuts on the non-road side are
completed first, followed by the bottom on that side. The advantage here is that the
hedge will be as thick as possible to resist debris flying through it onto the road. The
side(s), top and then the bottom can then be cut from the roadside.
Never cut the other side of the hedge with the rotor facing towards you. Debris
would have a direct path to you and you are more likely to hit dangerous objects,
as you cannot see them.
7.11
CUTTING THICKNESS
The below is a guide to maximum sizes.
7.12
REMOVING FOREIGN OBJECTS OR BLOCKAGE FROM THE MACHINE
Refer to section 2.8 – Accident prevention when removing a foreign object or
blockage.
If during operation, a knocking sound is heard or the cutting head stalled then there will
be a foreign object such as a large stone, tire, wire, etc or a build-up of material within
the cutting head area. Stop the cutting head immediately using the rotor stop button
along with tractor movement.
If possible lift the cutting head away from the material being cut. Adjust the angle at the
cutting head so that the obstruction is visible to the operator. Upon seeing the
obstruction the operator can now asses if it can be removed by reversing the rotor or if
it needs to be removed manually.
Before reversing the cutting head rotor re-position the cutting head horizontally in midair within 1 meter of ground level. Then reverse the rotor for approximately 10 seconds.
After reversing check to see if the obstruction has been removed.
91
Cutting head
1 meter
If the obstruction has still not been removed it’ll need removing manually. Ensure that
the cutting head is lowered to the ground or supported in such a way that hydraulic or
mechanical failure cannot injure any personnel. Position the Cutting head vertically
upright so the rotor can be accessed. Perform a ‘SAFE STOP’ procedure before
proceeding to leave the tractor cab. Using appropriate PPE and the safest method
possible remove the obstruction until the rotor is free to turn. Adjusting the cutting head
nose or roller to gain access may also help with clearing the cutting head.

with the ground
92
7.13
REACH AND WORKING ON SLOPES
See section 2.7 for accident prevention when operating.
The considerable reach of any hedgecutter combines with the weight of the head to
produce a large overturning effect on the tractor. The operator should remain aware of
the danger this can present, particularly on slopes; where the tractor may already not
be as stable as it would on a flat surface.
When moving between bouts of cutting always retract the booms. High shock loads
can be generated when moving at speed with the booms outstretched and these could
initiate fatigue cracking in the booms. If cracks begin they will lengthen even under light
loads.
7.14
BREAKBACK
See section 2.7 for accident prevention when operating.
The booms are protected when travelling in a forward direction by a relief valve
mounted on the slew cylinder. The booms are not protected in event of a high-speed
collision, or when travelling backwards.
Do not attempt to use the machine when travelling backwards.
Neither the booms, nor the obstacle, will be protected in a high speed collision.
When the breakback operates, stop the tractor’s forward movement immediately and
reposition the head by lifting over any obstacle before resetting the breakback position.
The slew cylinder is also equipped with check valves to ensure that the arms are held
securely in the transport position. Do not remove the relief cartridge, or reduce its
setting, as this would allow oil to bypass the checks. Increasing this relief valve
pressure without being authorised to do so by Shelbourne Reynolds will invalidate
warranty as the machine components may see excessive forces which may result in
component failure.
On HD700 trimmer controls an auto-return function is fitted as standard. With autoreturn switched on the machine senses if the booms have broken back and if so
automatically returns them to the working position. This function must be switched off
for transportation.
93
7.15
TELESCOPIC ARM
See section 2.7 for accident prevention when operating.
Telescopic outer arms are an option on HD700 trimmers. These give an extra 1.2m
(6.0mT), 1.5m (7.0T) or 1.83m (8.0T) of horizontal reach, which can be useful for high
hedges, deep or wide ditches and banks, while still keeping a compact arrangement for
close work when closed-in.
7.16
VARIABLE FORWARD REACH (VFR)
See section 2.7 for accident prevention when operating.
VFR booms are an option on HD700 trimmers. This boom configuration allows the
operator to bring the cutting head alongside the tractor. The head can be positioned
forwards for improved operator visibility and comfort.
94
7.17
NARROW LANE BRACKET
See section 2.7 for accident prevention when operating.
Narrow lane bracket is an option on all models. This feature allows the head to rotate
up 53 degrees using the tractor spool valve (see section 6). Using the narrow lane
bracket enables the operator to tuck the trimmer booms and head behind the tractor
wheel when cutting the side of a hedge when working within narrow lanes. It’s not
recommended that the narrow bracket is used when cutting the top of a hedge or verge
as this may expose the cutting flail and therefore increase the risk of debris or objects
being ejected.
Beware of showering debris over tractor cab.

7.18
DEBRIS BLOWER KIT
See section 2.7 for accident prevention when operating.
A debris blower kit can optionally be fitted at the rear of the Powerblade. The blower is
powered from the tractor hydraulics.
The return oil must go directly through a free flow connection i.e., filler plug. Do not use
a quick release coupling, through a spool valve on the return line.
96
Set the valve to
fully open, fully
anti-clockwise
To ensure the fan is running smooth turn the tractor spools flow down to between 30 –
40 l/min or if the fan blower is hunting turn the tractor spool flow down until it runs
smooth. Excessive tractor flow may cause heat build-up for both the tractor and the
debris blower.
Check the fan speed is running at 2500rpm optimum (2800rpm Maximum). Adjust the
valve to obtain the correct speed then lock off.
Ensure PTO disengaged when adjusting the valve during set up of the debris
blower valve.
Ensure that both hoses are correctly connected before operating the blower.
The debris blower is suitable for clearing cuttings from the public highway or when
on hard standing areas. The exit shoot can be angled for best affect. It’s
recommended that the blower is used only on the final pass and is not used
continuously. Continuous use may cause overheating and dramatically shorten the life
of the hydraulic components.
To operate use the tractor spool controls (see tractor operator manual).
97
7.19
OVERHEAD POWER LINES (OHPLs)
See section 2.7 for accident prevention when operating.
The operator should always take care to minimise the height of the machine in its
transport position. The operator should also be aware of any obstructions overhead,
such as power line, telephone lines or bridges. Before starting out on a journey it’s
recommended that the operator measures the highest point of the tractor and trimmer
combination (this may be different depending on tractor make or model and can even
change depending the position of the Powerblade is being carried on the tractor 3 point
linkage.
When working near OHPLs and outlines there is high risk of electric shock. There is
also high risk of flashover or arc (electricity can jump across gaps) even if you do not
contact the wires but are just working close to them (the higher the voltage the larger
the gap which electric can jump). Anyone contacting the machine or equipment in
these circumstances risks a serious or fatal electric shock.
OHPLs typically carry electricity at voltages from 11kV to 400kV. These wires are
typically not insulated (bare) cables. The height of these lines varies depending on the
voltage being carried. Lowest height OHPLs are those carrying 11kV to 33kV at a
minimum height of 5.2 meters above ground.
HD700 trimmers are capable of reaching higher than 8 meters which means there
is high risk of the machine being able to contact the wires.
See below the minimum heights above ground level and the exclusion zones for
OPHLs.

Never allow any part of the machine to enter the exclusion zone.
Operation of any part of the Powerblade or tractor within 10 meters horizontally of an
OHPL is not recommended. However if you cannot avoid doing so and the lines cannot
be made dead the operator should perform a risk assessment and agree a safe system
of work while ensuring to keep clear of all exclusion zones.





Understand when working near OHPLs there is high risk of electric shock and
also high risk of flashover or arc.
Contact the local distribution network operator (DNO) who can advise on line
heights, minimum vertical clearances distances and precautions to take.
Find out the maximum height and maximum vertical reach of your machine (see
section 3) before working near power lines.
Find out the routes of all OHPLs within your working area.
If in doubt DO NOT work near overhead power lines.
If you come into contact with an OHPL
 Stay in the cab of the machine and lower any raised parts in contact with the line
or try to drive the machine clear, if you can.
 Inform the DNO immediately (display the telephone number in the cab or keep it
on your mobile phone).
 Electrocution is possible if anyone touches both the machine and the ground at
the same time. If you need to get out jump well clear so that no simultaneous
contact is made between you, the vehicle and the ground. Do not touch any
wires. Stay clear and warn others not to approach.
 Get the DNO to disconnect the supply. Even if the line appears dead, do not
touch it, or any part of the machine. Contact with the line may cause the power
supply to trip out temporarily and it may be reconnected and re-energised
automatically, without warning.
 Never touch an overhead line that has been brought down by machinery, or has
fallen, e.g. in a storm. Do not try to disentangle equipment, until you have
received confirmation that the line has been de-energised and made safe.

SECTION 8:
MAINTENANCE AND STORAGE
Refer to section 2 for safety procedures.
8.1
LUBRICATION
Refer to section 2.10 for accident prevention when servicing / adjusting the
machine.
Both rotor bearings should be greased every 10 hours (daily). All other grease nipples
at the various pivots of booms, cylinders and roller bearings should be greased every
50 hours (or weekly).
Brand of grease recommended: Total multis complex EP2 grease.
The telescopic wear pads can be lightly greased if desired. If upon extending and
retracting the telescopic outer boom movement is not smooth lightly grease the wear
pads. Note that the telescopic cylinder does not need regular greasing as it does not
articulate.
The following transfer will be found on the machine –
8.2
PTO SHAFT
Refer to section 2.5 for accident prevention when using the PTO shaft
Grease both universal joints every 10 hours( or daily). Every 100 hours (or every 2
weeks), separate the telescoping members and grease along the length of the inner
shaft.

GEARBOX
Refer to section 2.10 for accident prevention when servicing / adjusting the
machine.
The gearbox is prefilled with a Synthetic gear oil, grade SAE 75W-90.
Brands of oil recommended are – Total SYN FE 75W90, BP Energear SHX SAE 75W90 or Mobilube SHC SAE 75W-90.
The gearbox capacity is 1.75 litres. Gearboxes should be drained and then refilled with
new oil after the first 50 hours and then every 1000 hours, or 2 years of use.
Check gearbox oil level regularly, a sight glass is fitted on the side to facilitate this.
Sight glass for
checking gearbox
oil level
8.4
CARE OF HYDRAULICS
See section 2.6 for accident prevention when using the hydraulic system.
Hydraulic component life can be radically shortened by contamination, overheating or
cavitation.
To minimise contamination – Ensure that any oil, containers and funnels used to top up
the system are scrupulously clean and that the filler area is cleaned thoroughly before
removing the cap. Follow the stated change intervals for the return and pressure filter.
When undertaking repair or servicing keep all components scrupulously clean. Ensure
the filler cap and breather are intact and always kept in place (moisture is a
contaminant as well as dirt).
102
To minimise overheating – Do not operate the machine above 540rpm PTO speed for
standard power machines and 800rpm for higher powered machines. Avoid stalling the
rotor, or operating the cylinders against their end limits, as in each case large amounts
of heat will be generated across the relevant relief valve.
To minimise the risk of cavitation – Ensure the oil level is maintained. Limit the PTO
speed when oil is cold. Ensure pump suction components are sound and tight, hose is
not squashed or kinked. Make smooth and limited changes to PTO speed. Cavitation is
usually accompanied by unusual noise: since cavitation can very rapidly ruin a pump it
is suggested that the machine is stopped immediately if noises are heard.
8.5
HYDRAULIC OIL
Refer to section 2.6 for accident prevention when using the hydraulic system
The tank is standardly prefilled with ‘Total Equivis 46’ an ISO VG 46 mineral hydraulic
oil. The oil tank holds 150 litres. Check the oil level regularly, a sight glass is fitted to
facilitate this.
Sight glass for
checking the oil
level
If a biodegradable oil is to be use, please contact Shelbourne Reynolds Ltd with the oil
specification to check suitability.
The interval at which the oil should be renewed will depend on the way in which the oil
is worked and how well it is looked after. It will eventually break down due to the effects
of contamination, oxidisation and condensation. These are caused by dirt getting into
the system, overheating and moisture ingress. Contamination can cause the oil to
become discoloured; as will oxidisation, but in the latter case along with a burnt smell.
Condensation will tend to give the oil a milky appearance.
In order to get the best life from the oil: only add clean oil, from clean containers and
with a clean funnel. Renew the return filter at the specified interval and clean the filler
cap area before removal. Avoid pushing the machine beyond its capacity, as this
generates large amounts of heat at the relief valves. Ensure that the filler cap and
breather unit are intact and always kept in place.
103
The machine is also fitted with an oil cooler located at the top of the oil tank. This
should be cleaned out regularly using high pressure air as the cooler matrex may
become blocked from dust and debris.
To clean out the oil cooler unscrew the three M8 fasteners enabling the steel cover to
be removed.
QTY3 x M8

Then remove the fan assembly from the oil cooler radiator matrix via the three fixings.
Oil cooler fan

Blow the radiator out using high pressure air until clear line of sight can be seen
through the radiator in all areas. Then refit the fan and the steel cover using the fixings

8.6
FILTRATION
Refer to section 2.6 for accident prevention when using the hydraulic system
The machine is equipped with a suction strainer, situated in the bottom of the tank.
When the oil is changed, or if the symptoms of cavitation are suspected (see Section 7)
clean the suction strainer.
An inline pressure filter is fitted to the auxiliary cylinder circuit. The filter is located at
the front (nearest the tractor) of the valve mounting plate. This must be changed after
50 hours and then every 500 hours.
A return filter is fitted to the machine, in a housing, which is part of the top of the
104
hydraulic tank. This must be changed after the first 50 hours and then subsequently
after every 500 hours. Note that if the filter is allowed to become clogged then the oil
will bypass the filter (to avoid the danger of the filter bursting) and could allow
contaminants into the tank and hence into the system components.
If another hydraulic component has failed then the return filter should also be renewed
forthwith.
8.7
HYDRAULIC HOSES
Refer to section 2.6 for accident prevention when using the hydraulic system
Check the hose ends and other hydraulic connections regularly to ensure there are no
leaks.
Check the hoses themselves regularly to ensure there is no damage to the sheathing; if
this has exposed the steel braiding it should be replaced. If the braiding itself has
become damaged then the hose should be replaced, as there is a danger it could
burst.
When working on the hydraulics, care must be taken to ensure that any connections
which are broken are remade in the same way; to ensure the safety of components and
that the movements of the machine remain consistent and logical. Ensure that any
replacement hose is of the same pressure rating as the hose it replaces. Always use 2
spanners when tightening hoses.

ACCUMULATOR SAFE REMOVAL
Refer to section 2.6 for accident prevention when using the hydraulic system
The accumulator must be pressurised for the lift float to function correctly. If the tap has
been moved to the de-pressurised position the head will constantly drop to the ground
even if the lift float is not engaged.
Ensure trimmer head is positioned on the ground before de-pressurising the
accumulator.
Ensure to de-pressurise the accumulator for safe removal.
See below shows the accumulator tap position at the top of the main hydraulic valve
block.

CARE OF THE ROTOR
See section 2.7 for accident prevention when operating.
Damage to the rotor can be costly to rectify. It undergoes a series of machining and
balancing operations to ensure that it will run smoothly.
Never operate at a speed greater than 540 rpm at the PTO for standard power
machines or 800 rpm at the PTO for higher powered machines.
It is unwise to use the tractor’s 1000rpm setting at a reduced engine speed – because
revving the engine would then over-rev the rotor by a considerable amount.
Always use the correct and genuine flails, bushes, bolts and nuts. Check them
regularly and keep them tight
106
A missing flail will put the rotor considerably out of balance, to an extent, which will
rapidly damage the rotor bearings and rapidly generate fatigue cracks in the head shell.
Shelbourne Reynolds cutting heads rotors use bolt on balance weight system. This
means it’s highly important that when replacing a flails or flail bolts, any balance
weights or washers which are in place should be returned to their position. Failure to do
this may result in the cutting head rotor becoming out of balance (see section 8).
If flail nuts, bolts, washers and balance weights have been removed without
Identifying of which position they’ve came from refer to the rotor balance chart.
8.10
FLAIL HEAD
Refer to section 2.10 for accident prevention when servicing/adjusting the
machine
Check for loose, broken or missing flails every 4 hours. Also check the rotor, roller and
other bolts on the head for tightness. Keep the flails reasonably sharp in order to give a
neat finish and lesson power consumption.
Always use the correct and genuine flails, bushes, bolts and nuts. Check them
regularly and keep them tight. Torque setting 270 Nm (200 lb/ft)
A missing flail will put the rotor considerably out of balance, which will rapidly damage
the rotor bearings and rapidly generate fatigue cracks in the head shell.
To balance the rotor for smooth running, suitable weights are attached as necessary at
the factory to relevant flail stations, even using slightly longer bolts. If flails are to be
removed ensure that the weights and bolts are returned to the same end of the same
station and with the bolt and nut in the same relative positions. These weights should
only be discarded if the rotor is re-balanced. Every machine has a rotor balance sheet
supplied in its manual canister from new. If the balance sheet is missing contact
Shelbourne Reynolds who hold a copy and will re-issue the balance sheet upon
quoting the machine’s serial number.

(105mm, 115mm & 130mm)
Balance weight versions 20g (2mm),

Replace spacers, bolts and nuts exactly when replacing flails. The flails themselves
should wear evenly and be replaced as a set. Should one flail be lost then the flail at
180°, one place along should be renewed at the same time to preserve the balance.
When ordering new bolts you will need to identify how many bolts are of which length –
‘standard’ is 95mm long, with lengths of 105mm, 115mm and 130mm being used
where balance weights are mounted.
When required to carry out maintenance on the inside of the cutting head ensure to
position the cutting head in contact with the ground while still being able to access the
flail area. Always perform a ‘Safe stop’ procedure before leaving the tractor cab.

BUSHES AND PINS
Bushes protect all pivots that are subject to movements. In the unlikely event these are
subjected to extreme wear they should be renewed promptly to reduce shocks, keep
movements predictable and protect the underlying steel.

RECOMMENDED TORQUE SETTING FOR FASTENERS
Refer to section 2.10 for accident prevention when servicing/adjusting the
machine
The table on the next page gives correct torque values for various size and grade of
fasteners.
-
Tighten all fasteners to the torques specified in the chart unless otherwise stated in
this manual.
Check tightness of fasteners periodically, using torque chart as a guide.
Replace hardware with the same strength fastener.
Torque figures are valid for non-greased or oiled threads and heads unless
otherwise specified. Do not grease or oil fasteners unless specified in this manual.
When using locking elements, increase torque values by 5%.

STORAGE
Refer to section 2.12 for accident prevention when cleaning and storing the
machine
Clean the machine thoroughly, making sure that high-pressure water does not contact
bearings, seals or electrical components. Avoid washing paintwork at very close range
or with very high pressure.
Release the tension in the drive belts, but replace the drive cover to keep the light out.
The machine should be stored undercover, to protect it from the effects of sun and rain.
Make any necessary repairs and then apply grease to all grease points until fresh
grease shows. Also, apply a layer of grease to all unprotected surfaces that are prone
to corrosion, in particular any exposed hydraulic cylinder rods. (This grease should be
carefully removed prior to the next use of the machine, as it will contain sufficient dirt to
damage the cylinder seals.
Disconnect and remove the electric joystick control unit and store in a safe secure
place.
