Adjusting The Motion Controls - Toro 74179 Operator's Manual

Adjusting the Motion Controls

Adjusting the Handle Neutral
If the motion control levers do not align, or move easily
into the console notch, an adjustment is required. Adjust
each lever, spring, and rod separately.
Note: The motion control levers must be installed
correctly; refer to Installing the Motion Control Levers,
page 15.
1. Stop the engine, remove the ignition key, and tilt the
seat forward.
2. Begin with either the left or right motion control lever.
Move the lever to the neutral (but not locked) position
and pull the lever back until the clevis pin (on the arm
below the pivot shaft) contacts the end of the slot (just
beginning to put pressure on the spring) (Fig. 47).
3. Check where the lever is relative to the notch in the
console. It should be centered allowing the lever to
pivot outward to the neutral lock position (Fig. 47).
4. If an adjustment is needed, loosen the nut against the
yoke.
5. Apply slight rearward pressure on the motion control
lever and turn the head of the adjustment bolt in the
appropriate direction until the lever is centered in the
neutral lock position (keeping rearward pressure on the
lever will keep the pin at the end of the slot and allow
the adjustment bolt to move the lever to the appropriate
position).
6. Tighten the nut and jam nut.
7. Repeat on the opposite side of the unit.

Adjusting the Hydraulic Pump Neutral
Note: Adjust the handle neutral first. That has to be correct
before the following adjustment can be made.
Danger
Mechanical or hydraulic jacks may fail to support
machine and cause a serious injury.
Use jack stand when supporting machine.
Do not use hydraulic jacks.
1. This adjustment must be made with the drive wheels
turning. First raise the frame and block it up so that the
drive wheels can rotate freely.
Warning
Engine must be running so motion control
adjustment can be performed. Contact with
moving parts or hot surfaces may cause personal
injury.
Keep hands, feet, face, clothing and other body
parts away from rotating parts, muffler and other
hot surfaces.
2. Slide the seat forward, disconnect the prop rod, and tilt
the seat fully forward.
3. Disconnect the electrical connector from the seat safety
switch. Temporarily install a jumper wire across the
terminals in the wiring harness connector.
4. Loosen the locknut at the ball joint on the pump control
rod (Fig. 47).
Note: The front nut of each rod has left-hand threads.
5. Start the engine, open the throttle 1/2 way, and release
the parking brake; refer to Starting and Stopping the
Engine, page 18.
6. Adjust the pump rod length by rotating the double nuts
on the rod, in the appropriate direction, until the wheel
is still or slightly creeps in reverse (Fig. 47).
7. Move the motion control lever forward and reverse,
then back to neutral. The wheel must stop turning or
slightly creep in reverse.
Note: The motion control lever must be in neutral while
making any adjustments.
8. Open the throttle to fast. Make sure that the wheel
remains stopped or slightly creeps in reverse. Readjust
if necessary.
9. Repeat on the opposite side of the unit. Tighten the
locknuts against the ball joints.
