as to fully engage the locking mechanism. At
this time, there should be a clearance be-
tween the differential lock pedal and the
Tractor step-plate of 1/4 of an inch. If this
adjustment is not correct, proceed as fol-
lows:
1. Loosen the clamp bolt securing the
pedal assembly to the differential lock shaft.
2. With the differ ential lock mechansim
fully engaged, position the pedal until there
is 1/4 of an inch clearance between the pedal
and the step plate.
3. Tighten clamp bolt securely.

~ To adjust the brakes, raise both rear
wheels off the ground. Remove the adjusting
hole covers. With a suitable screwdriver,
tighten the adjusting screws until they are
tight and the wheels cannot be rotated. Back
off the adjusting screws until there is no
longer a drag on the drums. Check drag
after each click.
NOTE: If the brakes are malfunc-
tioning due to very damp climatic
conditions, it may be necessary to
"burnish-in" the linings before ad-
justment. With the rear wheels
raised, run the Tractor in high
range-first gear. Lock one brake
and partially apply the other brake
until the brake drum is too hot to
touch. Repeat the operation on the
opposite brake. Allow drums to
cool, then adjust. Use extreme
care when carrying out this opera-
tion.
Check the master brake setting (both
brake pedals locked together). Apply the
master brake while driving the Tractor on
level ground. The Tractor should come to a
stop in a straight line. If Tractor pulls to
one side, the brake linkage requires ad-
justment. Lengthen or shorten linkage so
Tractor stops in a straight line. (See Figs.
77 and 78.)
