Control Lever Neutral Adjustment
Before considering any adjustment, check the tire air
pressure and make certain hydraulic system oil is at
operating temperature. Unequal tire pressure will cause
the mower to drift to one side. Refer to “Tire Inflation
Chart” on page 17 and page 35.
Fine adjustment to the steering is made with the
adjustable pump linkage rods located between the control
lever and pump arms. Refer to Figure 3-2.
Neutral is properly adjusted when the control levers are in
the neutral position and the drive wheels are not turning.
If the mower creeps in the neutral position the control
linkage may be adjusted as follows:
9.
Raise and block the mower up so the drive wheels are
off of the floor.
!
WARNING!
Make certain mower is secure when it is raised and placed on
the jack stands. The jack stands should not allow the mower to
move when the engine is running and the drive wheels are
rotating. Use only certified jack stands.
10. Position the control levers in the neutral position.
Disengage the blades.
11. Start the engine and observe which way the wheels
are rotating.
12. 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. Refer to Figure 3-2. Repeat for the opposite
side if necessary.
13. 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. Refer to Figure 3-2. Repeat for the
opposite side if necessary.
14. When both wheels remain in neutral, tighten the jam
nuts to lock the turnbuckle in place.
15. Test again by moving the control levers forward and
backward before returning them to the neutral
position. If the tires are in neutral, the unit is now ready
for operation.
Steering Dampener
Refer to Figure 3-3:
The steering dampeners are incorporated into the unit to
provide some resistance when the control levers are
moving forward or rearward. To set the steering
dampeners in the correct operating position follow these
steps:
1.
Place the control lever in the neutral position.
2.
Loosen the steering dampener’s rear ball stud.
3.
Pull the dampener spring housing, to the rear, past the
point that the internal spring is engaged.
4.
Release the dampener spring housing and allow the
internal spring to bring the housing back to the neutral
position.
5.
Tighten the nut on the steering dampener’s rear ball
stud.
6.
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 through 6.
