SNOWBLOWERS
This manual is for both Commercial Hydraulic Snowblowers and Commercial PTO
Drive Snowblowers. The hydraulic models come in 60”, 74” and 84” widths. The PTO
drive model is only available in an 84” width. Hydraulic models come with four different
motor series. Hydraulic output on the equipment running the Snowblower must match
the requirement for each motor series for the Snowblower to work. The hitch is a skid
steer fixed type of quick hitch. The PTO drive model runs at 540 rpm. It is supplied
with category 2 hitch pins. There is a shear bolt on the auger and two on the PTO
shaft to protect the machine from damage if a large object is picked up. All
Snowblowers come with a hydraulic chute control as standard.

OPERATING INSTRUCTIONS
1. HYDRAULIC DRIVE: All snowblower hydraulic blocks are set at the factory for a
2800 - 3000 psi system. Refer to the section on the hydraulic control block if your
system does not fall into this range.
2. ALL: Depth of the cut can be partially controlled by tilting the snowblower forward or
backward.
3. PTO DRIVE: Adjust the top link of the tractor hitch so the snowblower is just slightly
tilted back when resting on the ground.
CAUTION: Excessive backward tilt may
cause the “U” joints to flutter resulting in PTO shear bolt failure.
4. PTO DRIVE: The inside holes on the hitch are spaced to fit a category 2 quick hitch
using the pins supplied. The hitch will also fit category 2 three point arms or
category 3 if you add bushings.
5. PTO DRIVE: Adjust the lower link sway chains or blocks on the tractor to restrict
movement of the blower when operating.
6. ALL: All snowblowers have a hydraulic control spout and spout deflector. Refer to
the hydraulic control block section. The pressure to the chute control is regulated by
the two modulating elements (#14a and #14b). Each controls the hydraulic pressure
in one direction. They are set at the factory to about
2 ½ turns. If the pressure is too low, the chute won’t turn. If the pressure is too high
you could damage the teeth on the spout control ring. To adjust the pressure, you
loosen the lock nut on the modulating valve and back off the adjusting screw till the
screw turns freely by hand. Turn the screw in till you feel it making contact and turn
in 2 ½ turns. Start with this setting to do any fine adjustment if necessary. Pressure
should not go over 1000 psi.
The deflector cylinder pressure is regulated by modulating element (#14a). It is set
at the factory to about 2 turns. If pressure is too low it will not operate. Excess heat
will be generated if it is set too high. Adjust if necessary as per previous paragraph.
Operating pressure should be about 700 psi.
7. ALL: Run the snowblower at low rpm to check operation before blowing snow.
8. PTO DRIVE: The blower has two shear bolts to protect the tractor and blower in
case a large object enters the blower. PTO shear bolt – two 5/16” x 1” (grade 8);
auger shear bolt – 5/16” x 1 ¼” (grade 5). Shear bolts should be fastened with a lock
nut or two jam nuts. These bolts must be tight to prevent wear of the bolts and bolt
holes.
9. PTO DRIVE: Never run PTO at over 600 rpm.
6
Commercial Snowblower
OPERATING INSTRUCTIONS – cont’d.
10. ALL: Chain tension on auger chain should be set at 3/8” to 1/2” slack.
11. LUBRICATION:
a) ALL: The gear teeth on the chute control should be periodically
lubricated with gun grease.
b) PTO DRIVE: PTO shaft universal joints and square shaft slide should
be periodically lubricated with a grease gun.
c) ALL: Regularly oiling the chain will significantly increase the life of the
chain.
d) PTO DRIVE: Use any 80-90 gear oil or multigrade with 80 minimum in
the gearbox up to the level plug height.
12. ALL: Periodically check all bolts for tightness. The bolt holding on the fan
and the bearing bolts are of particular importance.
13. HYDRAULIC DRIVE: Always use goggles and gloves when checking for
hydraulic leaks. Use a piece of cardboard instead of your hands to look for
leaks.
14. ALL:
Always shut off snowblower for servicing or unplugging. Disengage
hydraulics or PTO shaft.
15. PTO DRIVE: Check the shear sprocket at the beginning of every season to
make sure it will spin freely. Clean to loosen if necessary.
16. ALL: When replacing bearings or tightening a loose bearing collar, always
tighten collar in the direction of shaft rotation using a center punch or a similar
tool.
17. HYDRAULIC DRIVE:
WARNING: The locking pins must extend through
the holes in the attachment when mounting the snowblower to an implement.
Levers must be fully down and locked. Failure to secure pins can allow
attachment to come off and cause injury or death.

Commercial Snowblower
HYDRAULIC CONTROL BLOCK
NON-STALLING-FAN FEATURE:
The Hydraulic Snowblower has a unique modulating element that keeps the blower fan
from stalling in an overloaded condition. This is accomplished by starving the hydraulic
flow to the front auger motor (which then stops feeding the fan) and diverts all of the
flow (and energy) to the main fan motor. As the fan clears itself, and the pressure
drops, the auger again begins feeding according to load. When the system is set up
properly the fan motor should not stall or plug up.
MODULATING ELEMENT SETUP:
For optimum performance the modulating element (#4) (Fig. 1) must be adjusted to
match the system pressure of the tractor being used. The factory setting is for a 28003000 psi system. If your system is less, you should make adjustments accordingly. For
adjustment:
Loosen the LOCK NUT (on the MODULATING VALVE (#4) and back off the
adjusting screw till the screw turns freely by hand, and then turn it in till you feel
the screw making contact with the pressure spring. One turn sets the pressure
up by about 600 psi.
For 2100 psi turn the screw in 3 ½ turns.
For 2400 psi, turn in 4 turns
For 2700 psi, turn in 4 ½ turns
For 3000 psi, turn in 5 turns.
If the fan stalls (in an over load condition), the (#6) element is set too high. If the Auger
slows and stops too soon, it is set too low. Once it is set it should not need to be
adjusted any more.
Since there are a number of unknown variables that are unique to almost every
situation, it is difficult to give an exact setting for a particular model. The variables are:
hose size and length, type and size of quick couplers, etc.

ASSEMBLY INSTRUCTIONS
1.
SPOUT ASSEMBLY FOR ALL SNOWBLOWERS: Remove two of the
grooved spout rollers to mount the discharge spout. Replace the two rollers
to hold spout in place. Install the 2 ½” x 8” cylinder on the spout using the
pins supplied.
2.
HYDRAULIC DRIVE: The 62” long hydraulic lines (#14) for the spout
deflector cylinder should be connected to the two ports on the hydraulic block
labeled C1 and C2 (see section on hydraulic control block for block drawing).
The 30” long lines (#15) from the spout control motor connect to the two ports
labeled M1 and M2 on the hydraulic block. The ¾” diam. x 84” main
lines (#21) connect to the implement. NOTE: The customer must supply the
appropriate tips to connect the main lines to the implement. A two-piece
wiring harness is supplied with all hydraulic snowblowers. The 45” part of the
harness is mounted on the snowblower. One end of this wire connects to the
control block. The plug end mounts on a bracket welded to the top edge of
the quick hitch. The 155” part of the harness with the switch is connected to
the plug on the harness mounted on the snowblower. A switch mounted in
the cab controls the spout and the deflector. The alligator clips attach to the
battery which acts as a power source. A schematic of the wiring harness is
included in this manual.
3.
PTO DRIVE:
1. Slide the two hitch adaptor weldments (#17) into the sleeves on the body.
These tubes are adjustable to three different positions. The correct position
for each individual tractor will be determined when mounting the snowblower
on the tractor (see section on mounting blower on tractor). Start with the
tubes pulled out to the last hole. Connect to the snowblower using pins (#71)
and linch pins (#73).
Mount the hitch Weldment (#7) to the body. The top arm of the hitch bolts on
top of the bracket on the body using a ¾” x 1 5/8” bolt, lock washer and hex
nut. The bottom of the hitch bolts to the outside of the two hitch adaptors
using 5/8” x 1 ¾” hex bolts, flat washers, lock washers and hex nuts.
2. Connect two 108” hoses (#76) to the hydraulic spout control motor and
two hoses to the cylinder on the discharge spout. Connect these hoses to the
tractor after mounting the snowblower on the tractor.
3. Mounting blower on tractor:
a)
The pins supplied with the snowblower are for a category 2 quick
hitch. The quick coupling hitch has two holes both at the top of the
hitch and at each lift arm. When using a quick coupler, the pins
must be in the inside set of holes. Use the outside set of holes
with a standard three-point hitch.
10
Commercial Snowblower
ASSEMBLY INSTRUCTIONS – cont’d.
b)
Using tape or a bright colored marking pen, mark on the outer
shields the position where the shaft is completely pushed together
and the position where you have a 4” overlap. Watch these marks
when moving the blower through all possible operating angles to
see that the PTO shaft stays within this range.
c)
With the engine on the tractor shut off, attach the PTO shaft. The
tractor end has a standard 6-spline end with a spring loaded locking
collar. The snowblower end has a clamp-style yoke with a 3/8” key
way. Slide the yoke onto the gearbox shaft with the 3/8” key
supplied. Lock the yoke in place with the ½” x 3” bolt and lock nut
fitted through the groove in the gearbox shaft. After tightening the
bolt, insert and tighten the 3/8” socket set screw supplied.
Caution: Always check to see that both ends of the PTO shaft are securely
attached every time the Snowblower is used. This should always
be done with the tractor engine off.
d)
e)
Check that the PTO shaft does not bottom or separate with the
blower in the extreme high and low positions. A longer optional
PTO shaft is available if the standard shaft is too short. Check for
free movement of all parts in various raised positions; particularly
the PTO shaft.
NOTE: Excessive U-joint wear and shear pin failure may result if
the tractor PTO angle exceeds 20º. The drawing below gives an
approximate way to check this angle. With the PTO half extended,
the tractor output should not be over 32 inches high. Use 34 inches
if the PTO is nearly compressed.
11
Commercial Snowblower
ASSEMBLY INSTRUCTIONS – cont’d.
4. PTO SHIELD: All PTO snowblowers are supplied with a PTO shield
(#18). To install, remove the two rear bolts at the top of the gearbox
(#34). Bolt the PTO shield to the gearbox by the hinges using these same
bolts. A utility spring (#68) keeps the shield in place. Hook one end of the
spring in the hole in the shield and the other end to the hole in the brace
under the gearbox.
CAUTION:
Do not run the snowblower without this shield in place.
REFILLING GEARBOX WITH OIL: If the gearbox requires refilling with oil
because of repairs to the gearbox, add oil to the level shown in drawing.
Check the level regularly using the plug in the lid. The correct level is
even with the bottom of the plug.
