Pivot Bar Adjustment
CAUTION: The tractor should be checked every 50
hours of operation for play between the frame
channel and the pivot bar.
Check and adjust the pivot axle as follows:
Raise the front of the tractor and set it on jack stands, so 1.
the front wheels are suspended above the ground.
WARNING! When jacking up the front end of the
tractor, always chock the rear wheels to prevent the
tractor from rolling, tipping or sliding off the jack
stands.
Move the ends of the pivot bar up and down to check for 2.
binding. If binding is present, loosen the lock nuts until
binding is eliminated. See Fig. 6-10
Grasping the ends of the pivot bar, attempt to move each 3.
end of the axle forward and rearward to check for side play
between the pivot bar and frame channel. If play is present,
gradually tighten the lock nuts until play is minimized.
Repeat steps 2 and 3 until minimum play without binding 4.
is achieved.
Raise the front of the tractor, remove jack stands, and lower the 5.
tractor to the ground. Remove the blocks from the rear wheels.
Lift Handle Adjustment (If so equipped)
The effort required to operate the implement lift handle can be
varied by loosening or tightening the lift assist spring adjusting
bolt on the left side of the tractor. See Fig. 6-11
The bolt can be accessed from the rear of the tractor, inside the left
rear wheel. Turning adjusting bolt clockwise will decrease the manual
effort required for lifting attachments; turning counterclockwise will
increase the effort needed to lift the attachment.
