Use Safety
Lights and Devices
Transport
Machinery Safely
▲ Slow moving tractors,
self-propelled equipment, and
towed implements can create a
hazard when driven on public
roads. They are difficult to see,
especially at night.
▲ Flashing warning lights and turn
signals are recommended
whenever driving on public roads.
▲ Comply with state and local laws.
▲ Use towing vehicle and trailer of
adequate size and capacity.
▲ Secure equipment towed on a
trailer with tie downs and chains.
▲ Sudden braking can cause a trailer
to swerve and upset. Reduce
speed if trailer is not equipped with
brakes.
▲ Avoid contact with any over head
utility lines or electrically charged
conductors.
▲ Engage park brake when stopped
on an incline.
Use A Safety Chain
Practice Safe Maintenance
▲ A safety chain will help control
drawn machinery should it
separate from the tractor
drawbar.
▲ Use a chain with the strength
rating equal to or greater than
the gross weight of the towed
machinery.
▲ Attach the chain to the tractor
drawbar support or other
specified anchor location. Allow
only enough slack in the chain to
permit turning.
▲ Do not use safety chain for
towing.
▲ Understand procedure before doing
work. Use proper tools and
equipment, refer to Operator’s
Manual for additional information.
▲ Work in a clean dry area.
▲ Lower attached implement to the
ground, put tractor in park, turn off
engine, and remove key before
performing maintenance.
▲ Allow implement to cool before
working on it.
▲ Disconnect battery ground cable (-)
before servicing or adjusting
electrical systems or before welding
on implement.
RCF3660 and RCF3672 Models Rotary Cutters 326-246M
▲ Maximum transport speed for an
attached implement is 20 mph. DO
NOT EXCEED. Never travel at a
speed which does not allow
adequate control of steering and
stopping. Some rough terrains
require a slower speed.
▲ As a guideline, use the following
maximum speed weight ratios for
an attached implement:
20 mph when weight of attached
implement is less than or equal to
the weight of machine towing the
implement.
10 mph when weight of attached
implement exceeds weight of
machine towing implement but
not more than double the weight.
▲ IMPORTANT: Do not tow a load
that is more than double the weight
of the machine towing the load.
▲ Do not grease or oil implement
while it is in operation.
▲ Inspect all parts. Make certain
parts are in good condition &
installed properly.
▲ Replace parts on this machine with
genuine Land Pride parts only. Do
not alter this machine in a way
which will adversely affect its
performance.
▲ Remove buildup of grease, oil, or
debris.
▲ Remove all tools and unused parts
from implement before operation.

DANGER
A Crushing Hazard exists when hooking-up equipment to a
tractor. Do not allow anyone to stand between tractor and
implement while backing-up to implement. Do not operate
hydraulic 3-point lift controls while someone is directly
behind tractor or near implement.
NOTE: Land Pride’s Quick Hitch can be attached to
the tractor to provide quick and easy 3-point hookup and detachment. See your nearest Land Pride
dealer to purchase a Quick-Hitch.
A 3-Point Category I or II hitch is required. The lower
3-Point arms of the 3-Point hitch must be stabilized to
prevent side-to-side movement. Most tractors have sway
blocks or adjustable chains for this purpose.

Deck Leveling & Cutting Height
Cutting Height Adjustment
There are 4 primary adjustments that should be made
prior to actual field operation:
Refer to Figure 3-1:
• Deck Leveling From Left to Right
• Cutting Height Adjustment
• Center 3-Point Link Adjustment
• Tailwheel Height Adjustment
!
CAUTION
Avoid direct contact with cutter blades by wearing a pair of
gloves. Cutter blades have sharp edges and burrs that can
cause injuries.
Proper adjustment of each of these items will provide for
higher efficiency, improved cutting performance, and
longer blade life. The following tools will be needed:
• Pliable tape measure
• Spirit or carpenters level
• Set of wrenches and/or socket wrench set
• Protective gloves
IMPORTANT: The front blade tip should be lower
than rear blade tip by approximately 1". The cutter is
subject to continuous material flow under the deck if
the rear blade is at the same height or lower than the
front blade causing horsepower loss, grass clumps,
blade wear, and frequent blade sharpening.
1.
! WARNING
Always disengage PTO, put tractor in park or set park brake,
shut tractor engine off, remove ignition key, and wait for all
moving parts to stop before dismounting from tractor.
Deck Leveling From Left to Right
Refer to Figure 3-2 on page 20:
1. Locate tractor and cutter on a flat level surface.
2. Use tractor’s hydraulic 3-Point control lever to lower
cutter until tailwheel makes contact with ground
surface.
3. Place a level on the cutter deck as shown. Manually
adjust one or both lower 3-Point lift arms until deck is
level from left to right. On some tractors, only one arm
can be adjusted vertically.
With gloves on, carefully rotate each blade tip to the
position shown in Figure 3-1.
2. Measure distance from cutting tip of front blade to
ground surface. This distance is the cutting height.
3. Using tractor’s 3-Point hydraulic control, raise or
lower the 3-Point arms until the front blade tip is at
the desired cutting height.
4. The top center link should be loose when deck rear is
supported by the tailwheel. If not, lengthen center
link until loose. Final adjustment will be made later.
5. Measure distance from cutting tip of rear blade to
ground. This distance should be slightly higher than
the front blade but not more than 1" higher.
6. If rear blade is lower than the front blade or is more
than 1" higher than the front blade, then the tailwheel
height must be adjusted. If needed, see “Tailwheel
Height Adjustment” instructions below.
7.
Repeat steps 1 through 6 until tailwheel and 3-Point
arms are adjusted to the desired cutting height.
8. Set tractor’s 3-Point hydraulic control stop once the

Transporting
! WARNING
When traveling on public roads, use accessory lights, SMV
sign, clean reflectors, and other adequate devices to warn
operators in other vehicles of your presence. Always comply
with all federal, state, and local laws.
Field Operation
!
IMPORTANT: Maintain correct PTO speed. Loss of
PTO speed will allow blades to swing back resulting
in ragged, uneven cutting. Excessive engine speed
will cause damage to the power train components.
IMPORTANT: Always disengage tractor PTO before
raising cutter to transport position.
1.
WARNING
Clear area to be cut of debris and other unforeseen removable
objects before cutting. Mark any potential hazards that cannot
be removed such as tree stumps, post, rocks, holes, and dropoffs with a visible flag.
Make sure driveline does not contact tractor or cutter
when raising cutter to transport position.
2. Reduce tractor ground speed when turning and leave
enough clearance so cutter does not contact
obstacles such as buildings, trees, or fences.
NOTE: Do not cut in wet conditions. Wet material
will build up on the deck underside creating poor
discharge, high wear, and additional horsepower.
3. Limit transport speed to 20 mph. Transport only with
a farm tractor of sufficient size and horse power.
Periodically disengage PTO, turn off tractor, remove
key & check for objects wrapped around blade
spindle. Block deck up before removing objects.
4. When traveling on roadways, transport in such a way
that faster moving vehicles may pass you safely.
Frequently inspect cutter for loose bolts and nuts.
Tighten all loose hardware as indicated in the
“Torque Values Chart” on page 36.
5. Shift tractor to a lower gear when traveling over rough
or hilly terrain.
Blade Engagement & Disengagement
Cutter blades can lock-up against each other during
start-up and shut-down especially if the tractor’s PTO
engagement is “INSTANT ON” and “INSTANT OFF”.
Following Blade Engagement and Blade Disengagement
instructions below will help eliminate blade lock up.
Blade Engagement
1.
Increase throttle to a speed just enough to get the
cutter started without stalling tractor while slowly
engaging PTO drivelines. Use tractor’s PTO soft start
option if available.
2. Ensure that all power shafts are rotating and that the
cutter is not vibrating excessively after ramping up to
PTO speed for at least 3 seconds. If excessive
vibration continues after 3 seconds at full PTO
speed, disengage PTO immediately, shut down
tractor, and remove switch key.
3. Check blades for a lock-up situation. Block cutter
deck up before working under the unit. Unlock
blades, remove support blocks, and repeat “Blade
Engagement” instructions.
Blade Disengagement
1.
Slowly decrease throttle speed until engine idle
speed is reached and then disengage PTO.
2. Engage tractor park brake, shut tractor engine off
and remove switch key. Stay on tractor until blades
have come to a complete stop.
IMPORTANT: Your cutter is equipped with free
swinging cutting blades to reduce shock loads when
striking obstacles. However, it is best to avoid
striking obstacles to extend cutter and blade life.
1.
Thoroughly inspect area to be cut for debris and
unforeseen objects. Mark any potential hazards.
2. Follow “Blade Engagement” instructions on right
side of this page to start cutter blades turning.
3. Optimum ground speed depends on density of
material being cut, horsepower rating of tractor, and
terrain. Always operate tractor at cutter’s full rated
PTO speed in a gear range that allows the cutter to
make a smooth cut without lugging the tractor down,
usually between 2 to 5 mph.
4. Follow “Blade Disengagement” instructions on right
side of this page to stop cutter blades. After the first
50 feet, disengage PTO and check to see that the
cutter is adjusted properly.
5. Do not engage PTO when cutter is in the fully raised
or lowered positions.
6. Periodically disengage PTO, shut down tractor,
remove key, and check for foreign objects wrapped
around the rotor shaft. Block cutter deck up before
removing objects.
7.
Frequently inspect cutter for loose bolts and nuts.
Tighten all loose bolts and nuts as indicated in the
“Torque Values Chart” on page 36.
8. For additional information, see “General Operating
Instructions” on page 24.

General Operating Instructions
It is important that you familiarize yourself with the
Operator’s Manual, completed Operators Checklist,
properly attached cutter to your tractor, made leveling
adjustments, and preset your cutting height before
beginning a running operational safety check on your
Land Pride Rotary Cutter.
The running operational safety check may now be done.
It is important that at any time during this safety check
you detect a malfunction in either the cutter or tractor that
you immediately shut the tractor off, remove its key, and
make necessary repairs and/or adjustments before
continuing on.
Make sure before starting tractor that the park brake is
engaged, PTO is disengaged, and cutter is resting on the
ground. Start tractor and set engine throttle speed at a
low idle. Raise cutter with tractor’s rear hydraulic lift
control lever to transport position making sure that the
driveline does not bind and does not contact the cutter
frame. Lower the cutter to the ground and at a low engine
speed engage the PTO. If everything is running smoothly
at a low idle, slowly raise the cutter to transport height
checking for bind or chatter in the driveline. Lower the
cutter to the ground and increase the tractor’s engine rpm
until it reaches the cutter full PTO operating speed of 540
rpm. If everything is still running smoothly, once more
raise the cutter to transport height to check for driveline
bind or chatter. Lower the cutter to the ground, return the
engine to a low idle, and disengage the PTO. Position the
adjustable stops on the tractor’s hydraulic lift lever so the
cutter can be consistently returned to the same cutting
and transport height.
You should now be ready to transport to your cutting site
at a safe ground speed. On roadways transport in such a
manner that faster moving vehicles can easily see you
and pass you safely. Reduce your speed when traveling
over rough and hilly terrain. Avoid quick or sharp steering
24
RCF3660 and RCF3672 Models Rotary Cutters 326-246M
corrections. Take extra care to ensure that the mower
doesn’t come into contact with obstacles such as trees,
buildings, or fences. Use accessory lights and
appropriate reflective devices to provide adequate
warning to pedestrians and other vehicle operators when
traveling on public roads and in the dark of night. Comply
with all local, state, and federal laws.
It is important that you inspect the area where you will be
cutting and clear it of safety hazards and foreign objects
either before or after you arrive at the cutting site. Never
assume the area is clear. Cut only in areas you are
familiar with and are free of debris and unseen objects.
Extremely tall grass should be cut twice to detect
potential hazards. In the event you do strike an object
stop the cutter and tractor immediately to inspect and
make necessary repairs to the cutter before resuming
operation. It really pays to inspect a new area and to
develop a safe plan before cutting.
You will need to maintain 540 rpm PTO speed and 2 to 5
mph ground speed to produce a clean cut. Make a tractor
gear and range selection that will enable you to maintain
these speed combinations. Generally the quality of cut is
better at lower ground speeds. Dense ground cover will
create the need to slow down even more. In certain
conditions tractor tires will roll grass down resulting in an
uneven cut when the grass fails to rebound. Should this
happen you may try reversing the direction of cut and/or
double cut to achieve the desired finish. Avoid very low
cutting heights especially on extremely uneven terrain.
Always cut downward on slopes and avoid crossing the
face of steep slopes. Avoid sharp drops and cross
diagonally through dips to prevent hanging up the tractor
and cutter. Slow down in turns. Remember to look back
often.
Now that you’re prepared and well briefed you may begin
cutting. Begin mowing by doing the following:
• Reducing tractor’s engine rpm.
• Make sure cutter is on the ground in cutting position.
• Engage PTO and then raise engine rpm to the
appropriate PTO speed.
• Begin cutting.
Make wide turns when possible. Three-point hitch and
optional Quick Hitch models can be lifted into transport
position to make tight turns and to reverse direction. Try
increasing or decreasing ground speed to determine the
effect on quality of cut. With a little practice you will be
pleased with what you and your Land Pride Rotary Cutter
can do. Whether you are done mowing, need to take a
break, or just need to make a few adjustments to the
cutter, remember to always do the following:
• Reduce tractor’s engine rpm and disengage PTO.
• Stop on level ground, set park brake, turn off engine,
and remove switch key.
• Stay on the tractor until the cutter blades have come to
a complete dead stop.

CAUTION
CAUTION
Keep blade bolt access hole covered at all times except when
servicing cutter blades. Make sure driveline is disconnected
from the tractor before servicing cutter blades.
CAUTION
Do not operate cutter with blades that are out-of-balance,
bent, excessively worn, excessively nicked, or with blade bolts
that are excessively worn. Such blades can break loose from
the cutter at high speeds causing serious injury or death.
Buildup of debris around moving parts and gearboxes is a fire
hazard. Keep rotating parts and gearboxes free from debris to
avoid serious injury and property damage.

Always disconnect driveline from tractor PTO shaft before
servicing underside of cutter. If tractor is started with PTO
engaged, the cutter can cause bodily injury or death.
Always secure cutter deck in the up position with solid
supports before servicing underside of cutter. Never work
under equipment supported by hydraulics. Hydraulics can
drop equipment if controls are actuated or if hydraulic lines
burst. Either situation can drop the cutter instantly even when
power to the hydraulics is shut off.
Do not alter Land Pride equipment or replace parts with other
brands. Doing so can cause equipment to perform improperly
and may lead to breakage that can cause bodily injury.
Replace parts only with genuine Land Pride parts.
!
Cutter Blade Maintenance
Improper oil level can cause bearing failure and be a fire
hazard. Maintain proper gearbox oil level to avoid serious
injury and property damage.
Do not attempt to straighten a bent blade or weld on a blade.
Do not attempt to modify a blade such as hard surfacing, heat
treating, cold treating, or by any other method. Always
replace blades with a new Land Pride blade to assure safety.
IMPORTANT: Replace cutting blades in pairs with
genuine Land Pride blades only. Replacing single
blades can result in an out-of-balance condition that
will contribute to premature bearing wear/breakage
and/or structural cracks in gearbox and/or deck.
Always inspect cutting blades before each use. Make
certain they are properly installed and are in good working
condition. Replace any blade that is damaged, worn, bent,
or excessively nicked. Small nicks can be ground out when
sharpening.
Remove cutting blades and sharpen or replace as
follows:
1.
Place tractor gear selector in park and set brakes,
shut engine off and remove ignition key.
2. Disconnect main driveline from tractor PTO and
secure cutter deck in the up position with solid

Method 1: Unscrew top vented dipstick (#1). Wipe oil from
dipstick and screw dipstick in without tightening. Unscrew
dipstick and check oil on dipstick. If below bottom level
mark, add recommended gear lube through dipstick hole
until oil reaches top mark on dipstick. Reinstall vented
dipstick and tighten.
IMPORTANT: Your cutter is shipped with a vented
dipstick packaged in the Operator’s Manual bag and
should have been installed in the gearbox by your
Land Pride dealer. Please see your Land Pride dealer
if vented dipstick was not included.
Method 2: Remove side oil plug (#2). If oil is below bottom
of plug hole, add recommended gear lube through top
dipstick hole until oil flows out of side plug hole. Reinstall
and tighten side oil plug (#2) and vented dipstick (#1).
Type of Lubrication: 80-90W EP Gear Lube
Quantity = Fill until oil reaches top mark on dipstick or
begins to flow out side plug hole in gearbox.
NOTE: Use a suction or siphon pump to drain
gearboxes of oil when there is not an oil drain plug.
