6.2 STEERING BRAKES (OPTIONAL)
The steering brake is designed to stop one wheel from
rotating. The opposite wheel continues to drive forward
and the unit pivots on the stopped wheel.
Connect the adjustment bracket to the cam lever arm
with a clevis pin.
1. Park the tractor in a level area. Put the parking
brake handle in the "OFF" (down) position. Loosen
the jam nuts on the right and left brake rod
assemblies. Turn the adjusting nuts until the brake
handle cross bar is parallel with the instrument
panel.
2. Move the brake handlebar all the way to the right
and measure the distance from the right end edge
of the brake handle cross bar to the right side of
the instrument panel. Move the brake handlebar all
the way to the left and make the same
measurement on the right.
3. Adjust the nuts until the difference between the two
measurements is 1/2" to 3/4" (13 to 19 mm). Turn
both adjusting nuts the same amount, clockwise to
increase the measurement difference or
counterclockwise to decrease the measurement
difference.
4. Tighten the jam nuts. Loosen the jam nuts below
the compression spring on the right side of the
tractor and adjust until one has the desired tension
for the right brake. Tighten the jam nuts.
6.3 ADJUSTING BRAKES
After each use wash dirt from the brakes with water.
Each day before operating, check all nuts, bolts, and
other fasteners. Replace missing or damaged pieces.
Brake service is required if the brakes do not stop and
hold the unit effectively.
Adjust the brake linkage as follows:
1. Stop the unit on a level surface.
2. Stop the engine and block the wheels so the unit
cannot roll.
3. Remove wheels and brake drums.
4. Inspect brakes and drum.
5. Loosen the jam nuts at the ends of right and left
brake rods or whichever side needs adjusting.
6. Turn bottom nuts a couple of turns clockwise to
shorten travel a bit.
7. Tighten all jam nuts.
8. Carefully test the operation of the wheel brakes. If
necessary, repeat the above procedures to get the
correct brake action.
IMPORTANT:
Replace brake shoes before lining is
worn to rivet heads.
If correct braking action cannot be achieved after
performing the above procedure, do the following:
9. Loosen the 5/16-24 nut and bolt which fastens the
cam lever arm to brake cam.
10.Remove cam lever arm from the brake cam.
Rotate the cam lever arm one spine to the rear and
put back on brake cam. Tighten nut and bolt.
