STEERING BRAKES
There are two steering brakes on the
tractor, one surrounding each steering clutch
drum. The brakes are 17-inch contracting
bands, actuated by pedals located on either
side of the operator's compartment. The
steering brake pedals should have approxi-
mately 3 inches of free movement (before
meeting resistance), measured at the pedal
pad
(Illust.
63). If the free movement becomes
less than 2 inches, adjustment is necessary.
Adjusting the Steering Brakes
Turn the brake rod adjusting knobs "A"
I(
Illust.
63)on each side of the tractor (located
under the dash and just above the engine
frame side channels) clockwise until the de-
sired pedal travel has been obtained.
When adjustment can no longer be made
with the knobs "A," turn the knobs counter-
clockwise until about 1 inch of the threads on
the linkage rods is covered. Then remove
the brake inspection covers located under
the rear section of the main frame on each
side of the tractor.
See Illust. 62.

and

between the steering clutch drum and the lining
at that point, and lock the set screw. The set
screw is accessible from the outside of the
tractor.
Loosen the jam nut "B" and turn the steer-
ing brake band adjusting bolt
"e"
until 1/64-
inch clearance has been obtained between the
steering clutch drum and the brake lining at
all points.
Lock the jam nut "B," install the covers,
and adjust the knobs "An to give 3 inches free
pedal movement.
Subsequent intermediate adjustments can
be made with the adjustment knobs "A."
Renewing the Brake Lining
The brake bands should be relined before
the lining is worn to a point where retaining
rivets will score the clutch drums. Squealing
and slipping brakes generally indicate when
such condition exists.
1. Release the tension on the brake rod
adjusting knob "An
(Illust.
63).
2. Remove the covers from the bottom of
the rear main frame.
