Features  
& Controls  
CONTROL FUNCTIONS  
A
The information below briefly describes the  
function of individual controls. Operating the  
tractor and dozer require the combined use of  
these controls and additional controls whose  
operation is described in the tractor Operator’s  
Manual.  
B
Please take a moment and  
familiarize yourself with the  
name, location, and function  
of these controls so that you  
will better understand the safe-  
ty and operating instructions  
provided in this manual.  
Figure 1. Control Locations  
A. Blade Angle Control Lever  
B. Attachment Lift  
A. Blade Angle Control Lever  
The blade angle release lever controls a spring-loaded  
plate which locks the blade in one of three positions.  
Use an abrupt pushing/pulling motion to release the  
angling mechanism and move the blade left or right.  
Push the angling lever forward fully to lock the blade in  
the left position. Pull the lever fully back to lock the  
blade in the right position. Move the lever slowly past  
center to lock in the centered position.  
NOTE: It is easier to change the angle of the blade with  
the attachment raised.  
B. Attachment Lift  
TRACTOR CONTROLS  
NOTE: Models with hydraulic or electric lift should refer  
to the tractor operator’s manual for lift control informa-  
tion.  
Before you begin operating the tractor with the dozer  
blade attachment, make certain you have:  
• Read and understood the instructions in the  
tractor Operator’s Manual.  
The attachment lift lever raises and lowers the dozer  
blade. See the tractor operator’s manual for control  
information. See the Adjustments section for proper  
attachment lift adjustment.  
• Become thoroughly familiar with all of the  
tractor controls and their operation, including  
how to safely and properly start and stop the  
unit.  
• Practice driving in an open area—without doz-  
ing—to become accustomed to the unit.

General  
Operating Instructions  
Checks Before Starting  
WARNING  
1. Refer to the Maintenance & Adjustments sections of  
this manual and perform any needed service. Also,  
refer to the tractor Operator’s Manual and perform  
any required service.  
Perform the Safety System Interlock test found in  
your tractor Operator’s Manual. If tractor does not  
pass the test, do not operate the tractor. See your  
authorized dealer. Under no circumstances  
should you attempt to defeat the safety system.  
2. Remove any objects from the work area which might  
interfere with plowing activity.  
Use caution when plowing a snow covered area.  
Snow can cover objects such as curbs, drop-offs,  
and other obstacles. Be familiar with the area you  
are plowing.  
3. Adjust the skid shoes to desired height. See Skid  
Shoe Adjustment.  
4. Make sure all hardware is present and secure.  
To prevent an explosion or fire, never store the  
tractor with fuel in the tank inside a building  
where an ignition source is present.  
Engine & Ground Speed Selection  
Always run the engine at full throttle.  
Set tractor speed to obtain the needed power to move  
the material. Operate at a safe speed, depending on  
conditions, so that you have complete control of the trac-  
tor. Rear wheel weights and chains are recommended  
for slippery surfaces.  
IMPORTANT NOTE  
To prevent damage to the unit, always  
raise the dozer blade BEFORE turning or  
backing up.  
A weight box is recommended for additional traction.  
DANGER  
OPERATING ON SLOPES CAN BE DANGEROUS  
Transporting  
For maximum ground clearance, transport the blade to  
and from work areas fully raised and angled straight  
ahead.  
Never operate on slopes greater than 17.6% (10°)  
which is a rise of 3-1/2 feet (106cm) vertically in  
10 feet (607cm) horizontally.  
Operate the unit at a slow ground speed when  
driving onto slope. Avoid using brakes to control  
ground speed.  
Starting & Stopping  
1. Start the tractor engine. Set engine throttle to full.  
2. Raise the attachment lift and travel to the work site.  
3. Set the angling control to the desired angle.  
4. Lower the attachment lift and begin plowing.  
5. Raise the plow before backing up.  
When operating on slopes that are greater than  
15 % (8.5°) but less than 17.6%, use additional  
wheel weights or counterweights.  
In addition to counterweights, use extra caution  
when operating on slopes. Drive UP and DOWN  
the slope, never across the face, use caution  
when changing directions and DO NOT START  
OR STOP ON SLOPE.  
6. To stop the tractor, set ground speed to neutral and  
set the parking brake. Before leaving the seat, stop  
the engine, set the parking brake, remove the key,  
and wait for all moving parts to stop.  
For additional traction, tire chains and wheel  
weights can be added. Maximum weight added to  
tractor should not exceed 35 lbs. per wheel.

General Operating Instructions  
Changing Angle of the Blade:  
Snow Plowing Tips  
See Figure 1 for location of Controls.  
• Determine the best snow removal pattern before  
beginning.  
NOTE: It is easier to change the angle of the blade with  
the attachment raised.  
• Plan the pattern so that you avoid pushing snow onto  
cleared areas.  
1. Raise the attachment lift.  
• When land contour permits, it is best to travel in the  
longest direction to minimize turning.  
2. Use an abrupt pushing/pulling motion to release the  
angling mechanism and move the blade left or right.  
Push the angling lever forward fully to lock the blade  
in the left position. Pull the lever fully back to lock the  
blade in the right position. Move the lever slowly over  
center to lock in the centered position.  
• In very deep or heavy snow, it may be necessary to  
make the first pass with dozer blade partially raised,  
then repeat each pass with the blade lowered to clear  
the material left on the surface. Also, it may be nec-  
essary to clear less than the full width of the dozer  
blade or reduce ground speed.  
Dozing Tips  
• Snow tends to freeze into solid banks when plowed  
off a driveway or other large area. Because of this  
you may want to plow snow several feet past the  
edge of the drive to allow space for future plowing to  
build up.  
• Determine the best dozing pattern before beginning.  
• When land contour permits, it is best to travel in the  
longest direction to minimize turning.  
• In very deep snow or gravel, it may be necessary to  
make the first pass with dozer blade partially raised,  
then repeat each pass with the blade lowered to clear  
the material left on the surface. Also, it may be nec-  
essary to clear less than the full width of the dozer  
blade or reduce ground speed.  
• If pushing snow past the edges of driveways or side-  
walks, be careful not to tear up the grass buried  
under snow next to the drive or sidewalk. Lift the  
blade several inches off the ground to avoid damag-  
ing the grass.  
• Spinning tires with tire chains can leave unsightly  
marks or permanent damage to asphalt or concrete  
driveways or sidewalks. Avoid sudden stops or  
starts.  
• When dozing, push the dirt to the desired location,  
then drag the blade backwards for final leveling. Pack  
down the dirt or gravel by driving the tractor over the  
leveled area.  
• Use any slight grade to your advantage, doze down-  
hill, and set the blade angle so that the plowed mater-  
ial is moving downhill as it leaves the blade.  
Storage  
Off-Season Storage  
IMPORTANT NOTE  
Refer to Tractor Operator’s Manual for  
important information concerning safely  
storing your tractor.  
1. Remove dozer blade and hitch from the tractor.  
2. Use water pressure or a brush to thoroughly clean  
the dozer blade.  
3. Paint, or lightly coat with oil, any area where paint  
has been worn or chipped away.  
Daily Storage  
4. Lubricate the dozer blade.  
1. Allow tractor engine to cool before storing in any  
enclosure.  
5. Store the dozer blade and hitch in a dry place.  
2. After dozing or plowing jobs are completed, hose or  
brush down the blade to remove excess dirt.  
3. Lightly oil all pivot points. Coat bare metal surfaces to  
prevent corrosion.

Maintenance  
WARNING  
Lubricate Dozer Blade  
To avoid serious injury, perform maintenance on  
the tractor or dozer blade only when the engine is  
stopped, parking brake is set and all moving parts  
have stopped. Always remove the ignition key  
before beginning maintenance or adjustments to  
prevent accidental starting of the engine.  
Lubricate the dozer blade as shown in Figure 2. Where  
an oil can is shown, wipe the area clean, apply a few  
drops of oil (SAE 30), then wipe up drips or spills.  
In general, linkage connections and other parts that have  
partial rotational or sliding movement should be lubricat-  
ed periodically with SAE 30 weight oil. Avoid applying  
excessive amounts of oil since this may cause a build-up  
of dirt around the lubricated area, making subsequent  
lubrication more difficult to accomplish.  
Schedule For Normal Care  
Care Required  
Schedule  
Clean debris from  
dozer blade.  
After each use.  
Lubricate dozer blade.  
Every 10 hours or at  
least once a year.  
Figure 2. Lubrication Points

Adjustments  
Skid Shoe Adjustment  
Slotted holes are provided to permit adjustment of the  
shoe assemblies for raising and lowering the blade to  
various working heights (see Figure 3).  
When cleaning snow from gravel or earth drives or  
walks, the shoe assemblies should be lowered fully to  
prevent blade contact with gravel or ground. When  
cleaning smooth hard surfaces like concrete, the shoe  
assemblies are normally placed fully up to allow the  
blade to scrape the surface.  
To adjust the skid, raise the blade off the ground and  
block with a piece of wood. Loosen the bolts (B, Figure  
3) and move the skid shoes (A) up or down to desired  
height. Tighten the bolts securely.  
Figure 3.  
A. Skid Shoes  
B. Bolts  
Spring Tension  
See Figure 4. This snow plow/dozer blade is spring  
loaded so that when the blade strikes a solid object, the  
springs will allow the blade to release as shown, rather  
than cause damage. The blade will go back to its original  
position after object is cleared.  
Figure 4. Dozer Blade “Released”  
See Figure 5. To adjust spring tension hold rear nut (B)  
and loosen front nut (E). Tighten rear nut (B) to increase  
spring tension, or loosen to decrease tension.  
For initial adjustment, tighten nut (B) on each eyebolt  
enough to expose about 3/4" (19mm) of thread. Tighten  
front nut (E) against rear nut (B) to lock adjustment in  
place.

Adjustments  
Lift Rod Adjustment  
In the fully raised position the blade should be 6” off the  
ground. In the fully lowered position, the lift rod should  
slightly compress the spring creating downward pressure  
on the blade.  
D
C
B
E
NOTE: Always adjust the lift height before and after  
adjusting the downward pressure.  
A
IMPORTANT NOTE  
DO NOT OVER-COMPRESS THE SPRINGS.  
In addition to providing downward pressure,  
the springs are an elastic medium that  
absorbs shocks caused by bumps and  
cracks in ground surfaces. Over-compress-  
ing the springs defeats this and may cause  
damage to the unit.
