& See figure llr After allowing the belt and pulleys to stop
turning, use two wrenches to tighten the locking nuts (B)
against turnbuckle (C). Tighten the locking nuts (B) one at a
time, while using the other wrench to hold turnbuckle (C)
from rotating.
9, Lower the seal deck- Place the shift lever in DRIVE posi¬
tion and check your adjustment while sitting in the tractor
seat by operating the engine at full throttle with the hydro¬
static lever in the neutral position,
FOOT PEDAL BRAKE ADJUSTMENT
The foot pedal brake should be adjusted so that it will stop
the tractor when it is moving backward, but not so tight to
prevent the foot pedal from traveling far enough to disengage
the clutch. If adjustment is required proceed as follows:
1. Lift the seat deck by following the instructions under
Raising the Scat Deck on pagelOt
Z
See figure 12, Use one open end wrench to hold nut (B)
stationary, and another wrench to turn nut (C) counter¬
clockwise to loosen it lightly.
3. Turning nut (B) clockwise will give more braking action
and turning it counter-clockwise will give less. The brake ad¬
justment can best be made by using the trial and error
method, and operating the tractor each time an adjustment
has been made. The best adjustment can be made by turning
nut (B) counter-clockwise until the foot pedal brake does
not work. Then turning it clockwise, one turn at a time, un¬
til the tractor will stop satisfactorily when rolling backward.
Thisis the correct adjustment. Further tightening may cause
the brake to drag, or prevent proper clutch disengagement.
4. After you are satisfied that the adjustment is correct use
one wrench to hold nut (B) stationary and another to turn
nut (C) clockwise to tighten the nuts securely together.
5. Lower the seat deck.
PARKING BRAKE ADJUSTMENT
Although the hydrostatic transmission may help prevent the
tractor from rolling when the engine is stopped, the parking
brake should be properly adjusted and used whenever the
operator leaves the tractor seat. The parking brake is actu¬
ated and adjusted independently of the foot brake. It is cor¬
rectly adjusted when it will prevent the tractor from rolling
either forward or backward and some resistance is felt when
it is placed in the engaged position. If it is too tight, it will
be difficult to place it in the engaged position. To adjust the
parking brake, proceed as follows:
1. See figure 13. NOTE: ALL DIRECTIONS GIVEN FOR
ADJUSTING THE PARKING BRAKE, ARE AS IF YOU
ARE STANDING AT THE FRONT OF THE TRACTOR
LOOKING BACK TOWARD THE PARKING BRAKE. Loo¬
sen nut (A) by turning it clockwise,
Z
See figure 13. After insuring the tractor is either on a level
surface or the wheels are blocked so it will not roll, pull for¬
ward on the parking brake handle (B) to disengage the park¬
ing brake.
3, Rotate parking handle (B) clockwise to tighten the park¬
ing brake, or counter-clockwise to loosen it- Turn the brake
one complete revolution when making any adjustment.
After turning the handle (B) one revolution place it in the
engaged position to check it for correct adjustment. The
correct engaged position is as shown in figure 13, with the
handle at approximately in the 11 o'clock position as you
Figure 13. Parking brake adjustment on right side of tractor,
face it from the front of the tractor.
4. After the correct adjustment has been made, use a wrench
to tighten nut (A) securely by turning it counter-clockwise.
TRANSMISSION NEUTRAL SAFETY
START SWITCH
If the engine starter will not actuate when the hydrostatic
control lever is in neutral, or will actuate when the hydro-
transmission control lever is not in the neutral position, the
neutral safety starting switch may need adjusting. The power
take off lever must be disengaged before the starter will
operate also. Adjust it as follows:
1. Raise the seat deck as explained on page 14 under Raising
the Seat Deck,
2. Place the hydrostatic transmission control lever back a-
gainst the neutral stop.
3. See figure 14. The neutral safety start switch is properly
adjusted when it is centered on pointer {C) and depressed
about 1/16" to 1/8". The two nuts (A) may be turned clock¬
wise or counter-clockwise to lower or raise the safety switch
and bracket (B) is dotted to allow it to be centered on
pointer (C). After adjusting the neutral safety switch place a
film of grease on pointer (C) where It contacts the switch.
4. Tighten the two nuts (A) against mounting bracket (C).
5. Lower the seat deck.
6. Check the adjustment by starting the tractor.
POWER TAKE-OFF CLUTCH ADJUSTMENT
See figure 15, The power take off clutch is properly adjusted
when pulley (A) moves 1/S" when the power take off con¬
trol lever is engaged and disengaged. If adjustment Is required,
proceed as follows:
1, Raise the seat deck, by following the instructions on page
14 under Raising the Seat Deck.
2- Place the power take off clutch control Lever in the en-
