WARNING:
Make certain machine is secure when it is raised
and placed on the jack stands. The jack stands should not allow
the machine to move when the engine is running and the drive
wheels are rotating.
Use only certified jack stands.
2. Position the control lever in the neutral position. Disengage the deck
clutch switch Fig. 5-2.
3. Loosen the nut on the steering dampener’s rear ball stud. Fig. 5-3
4. Remove the cotter key that connects the brake link to the brake pawl.
Remove the brake link from the brake pawl. Fig. 5-8
5. Start the engine and observe which way the wheels are rotating.
6. If wheel(s) are rotating forward, loosen the jam nuts on the pump
linkage rods and rotate the rod to lengthen the steering control
linkage until the wheel(s) come to a stop. Fig. 5-3
NOTE: The left linkage controls the left integrated pump/motor and
the right linkage controls the right integrated pump/motor.
Repeat for the opposite side if necessary.
If wheel(s) are rotating in reverse then loosen the jam nuts on the
pump linkage rods and rotate the rod to shorten the steering control
linkage until the wheel(s) come to a stop. Fig. 5-3
Repeat for the opposite side if necessary.
7. When both wheels remain in neutral, tighten the jam nuts to lock the
pump linkage rod in place.
8. Test again by moving the control levers forward and backward
before returning them to the neutral position. If the tires remain in
neutral, the unit is now ready for operation.
9. Shut the engine off. Place the control levers in the neutral position
and reconnect the brake link to the brake pawl. Re-insert the cotter
key. Fig. 5-8
10. Re-tighten the steering dampener’s rear ball stud after adjusting the
dampener per the following instructions:
Steering dampener
The steering dampener (Fig. 5-4) is spring loaded to return the control
levers to the neutral position from the reverse position. This gives the
operator a sense of neutral during operation.
If the tractor does not return to neutral from reverse then adjust as
follows:
To set the steering dampeners in the correct operating position follow
these steps:
1. Shut engine off, place control levers in the park brake position,
disengage deck clutch, remove ignition switch key and disconnect
negative battery cable before doing any adjustments.
2. Place the control lever in the neutral position. Fig. 5-2
3. Loosen the steering dampener’s rear ball stud.
4. Pull the dampener spring housing, to the rear, past the point that the
internal spring is engaged.
5. Release the dampener spring housing and allow the internal spring to
bring the housing back to the neutral position.
6. Tighten the nut on the steering dampener’s rear ball stud.
7. To check, move the control lever to the reverse position and release.
The control lever should return to the neutral position. If not, repeat
steps 1 thru 6.
Control lever adjustment
The control levers can be adjusted for operator comfort. By loosening
the cap screws that attaches the upper control lever to the lower lever (Fig.
5-5), the upper control lever can be pivoted to fit the operator’s personal
preference.
The control levers can also be adjusted up and down. Remove the cap
screws and slide the upper control lever up or down and align the holes in it
with the holes in lower lever. Re-install the cap screws and tighten.
The control levers should be adjusted so that they align with each other
when in the neutral position.
Park brake spring adjustment
Occasionally check the park brake spring adjustment using the following
method:
1. Shut engine off, place control levers in the park brake position,
disengage deck clutch, remove ignition switch key and disconnect
negative battery cable before doing any adjustments.
2. Position the control lever in the neutral position.
3. Make sure the brake actuator lever and the brake link are all the way
down. Fig. 5-6
4. Tighten the nylock nut on top of the spring assembly until it is
touching the top flat washer.
Do not compress the spring. Fig. 5-7
5. Place the control lever in the park brake position. The brake pawl
should now be activated and engaging the integrated pump/motor
brake gear. Fig. 5-8
6. Repeat steps 2 thru 4 for the other side.
