ADJUSTMENTS
Skid Shoe Adjustment
When clearing snow off smooth surfaces such as con-
crete or asphalt, the scraper bar should scrape the sur-
face. On surfaces such as gravel, the scraper bar
should be set high enough so that it will not pick up
debris.
1. Loosen the capscrews (A, Figure 3) securing the skid
shoes.
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 capscrews (A, Figure 3).
Rotate / Replace Scraper Bar
If the scraper bar has become worn, it can be rotated
end over end once, or replaced.
1. Raise the dozer blade and support the skid shoes
using wood blocks.
2. Remove the carriage bolts (B, Figure 3), lockwashers
(C), and nuts (D).
3. Rotate the scraper bar end over end, or replace the
blade.
4. Secure the scraper bar to the blade using the car-
riage bolts (B, Figure 3), lockwashers (C), and nuts
(D), removed in step 1.
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-com-
pressing the springs defeats this and
could cause damage to the unit.

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.
When performing service work, support the blade
using wood blocks placed under the scraper bar or
skid shoes.
Never put hands or feet under the dozer blade.
