Check the Drawbar Wear Blocks
Inspect the stop wear blocks (1) for excessive wear. If
there is wear on the blocks, rotate them 90° to provide
a new wear surface for the drawbar to ride against.
Measure the clearance between the top bridge plate
(2) and the drawbar support (3). If there is 3 mm
(1/8
") or less clearance, replace the wear block under
the bridge plate.
Remove the stop wear blocks (1).
Support the drawbar (4) and remove the bridge plate
bolt (5). Lift off the top bridge plate (2). Replace the
wear block and reassemble the bridge plate. Torque
the bridge plate bolt (5) to 952 N·m (702 ft-lbs).
Replace the stop wear blocks (1).
NOTE: The wear block under the bridge plate
is attached to the plate with four cap screws.
Be sure to reinstall the wear block cap screws during
reassembly.

Steam Cleaning the Tractor
If mud or debris is allowed to build up on the tractor,
it can cause a safety hazard as well as detract from
the appearance of the tractor.
Using a steam cleaner or high pressure washer, clean
the tractor from end to end, paying particular attention
to the underside and wheel area.
CAUTION: ALWAYS SHUT THE TRACTOR OFF WHEN
CLEANING OR SERVICING.
IMPORTANT: Never spray cold water on a hot tractor
engine. The sudden temperature change may cause
cracking of the cast iron components. The cold water
hitting the injection pump can cause the components
rotating inside the pump to seize due to the sudden
temperature change.
IMPORTANT: Do not use caustic soaps that can cause
damage to the paint finish on the tractor. Read the
manufacturer’s instructions carefully on the soap
package.
IMPORTANT: Do not spray high pressure water into
the cooler/radiator area of the front grille. Damage to
the cooling fins will result.
