TRACTOR CONTROLS
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.
• Become thoroughly familiar with all of the tractor controls and their operation, including how to safely and properly start and stop the unit.
• Practiced driving in an open area—without dozing—to become accustomed to the unit.
Features
& Controls
A. Blade Angle Release Lever
The blade angle release lever controls a spring-loaded tab which locks the blade at specific angles.
Squeezing on this lever pulls the locking tab out of it’s locked position, and allows the blade to be angled. Releasing the lever allows the locking tab to lock into an adjustment slot.
B. Angling Control Lever
The angling control lever is used (with the blade angle release lever) to manually change the blade angle.
C. Attachment Lift
The attachment lift pedals (see inset above) raise and lower attachments such as the dozer blade.
To RAISE an attachment, depress the REAR attachment lift pedal. To LOWER an attachment, depress the FRONT attachment lift pedal.
D. Two-Speed Control
The two-speed control allows the operator to switch the transmission into high or low-speeds, and to disengage the transmission into a NEUTRAL (free-wheeling) position.
Select the low-speed for all Dozing work and high­speed for travelling to and from work areas. DO NOT SHIFT WHILE MOVING. See the Tractor Operator’s Manual for more details.

Checks Before Starting
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.
2. Remove any objects from the work area which might interfere with plowing activity.
3. Adjust the skid shoes to desired height. See Skid Shoe Adjustment.
4. Make sure all hardware is present and secure.
Engine & Ground Speed Selection
Always run the engine at full throttle. Normally, a slow ground speed is best for plowing. The
heavier the material, the slower the recommended ground speed. When plowing always set the 2-Speed control to LOW.
Transporting
1. Use the attachment lift to raise the dozer blade.
2. Adjust ground speed according to surface conditions. Select a slow ground speed when transporting on a slippery surface.
General Operating Instructions
WARNING
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.
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.
To prevent an explosion or fire, never store the tractor with fuel in the tank inside a building where an ignition source is present.
Starting & Stopping
1. Start the tractor engine. Set engine throttle to full.
2. Raise the attachment lift and travel to the work site.
3. Stop the tractor and set the Two-Speed control to LOW.
4. Set the angling control to the desired angle.
5. Lower the attachment lift and depress the forward ground speed pedal to plow.
6. Raise the plow before backing up.
7. To stop the tractor, release the ground speed control pedals. Before leaving the seat, stop the engine, set the parking brake, remove the key, and wait for all moving parts to stop.
DANGER
OPERATING ON SLOPES CAN BE DANGEROUS
Never operate on slopes greater than 30 percent (16.7°) which is a rise of three feet vertically in 10 feet horizontally.
Operate the unit at a slow ground speed when driving onto slope. Avoid using brakes to control ground speed.
When operating on slopes that are greater than 15 percent (8.5°) but less than 30 percent, 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.
IMPORTANT NOTE
To prevent damage to the unit, always raise the dozer blade BEFORE turning or backing up.
RAISE dozer blade
before transporting,
turning or backing up!

Daily Storage
1. Allow tractor engine to cool before storing in any enclosure.
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.
IMPORTANT NOTE
Refer to Tractor Operator’s Manual for important information concerning safely storing your tractor.
General Operating Instructions
Changing Angle of the Blade:
See Figure 1 on page 3 for location of Controls.
1. Fully raise the attachment lift by depressing the REAR attachment lift pedal (C, Figure 1).
2. Squeeze the blade angle release lever (A) to release the locking tab and allow the blade to pivot.
3. Push or pull on the angling control lever (B) to change the angle of the dozer blade as desired.
4. Stop squeezing the blade angle release lever (A) and make certain the blade is locked into position by pushing or pulling slightly on the angling control lever until the tab locks into one of the slots.
Dozing Tips
• 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 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 necessary to clear less than the full width of the dozer blade or reduce ground speed.
• 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 down­hill, and set the blade angle so that the plowed mater­ial is moving downhill as it leaves the blade.
Snow Plowing Tips
• Determine the best snow removal pattern before beginning.
• Plan the pattern so that you avoid pushing snow onto cleared areas.
• When land contour permits, it is best to travel in the longest direction to minimize turning.
• 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 nec­essary to clear less than the full width of the dozer blade or reduce ground speed.
• 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.
• If pushing snow past the edges of driveways or side­walks, 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 damag­ing the grass.
Storage
Off-Season Storage
1. Remove dozer blade from the tractor. Hitch can remain installed if other front mounted attachments are to be used.
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.
4. Lubricate the dozer blade.
5. Store the dozer blade and hitch in a dry place.

Maintenance
Schedule For Normal Care
Care Required Schedule
Clean debris from After each use. dozer blade.
Lubricate dozer blade. Every 10 hours or at
least once a year.
Lubricate Dozer Blade
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 lubricat­ed 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.
WARNING
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.

ADJUSTMENTS
Skid Shoe Adjustment
On smooth surfaces such as concrete or asphalt, the scraper bar should scrape the surface. On surfaces such as gravel, the scraper bar should be set high enough so that it will not pick up debris.
1. Loosen the nuts securing the skid shoes (see Figure 3).
2. Raise or lower the scraper bar to the desired height. Use wood blocks to hold the blade in position.
3. Set the skid shoes so that they are in contact with the ground and tighten the skid shoe nuts.
Lift Height Adjustment
To adjust the lift height:
1. Fully raise the attachment lift and shut off the engine. Set the parking brake and remove the key.
2. Loosen the nuts (C, Figure 4).
3. Turn the lift height bolts (D) until the dozer blade is at the desired height and level.
4. Hold the lift height bolts (D) in position and lock in place with the nuts (C).
Downward Pressure Adjustment
1. Fully lower the attachment lift and shut off the engine. Set the parking brake and remove the key.
2. Turn the nuts (E) evenly until the desired downward force is achieved.
Do not “lock-up” the springs. The springs should have some flex.
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-compress­ing the springs defeats this and may cause damage to the unit.
