HYDRO-DRIVE WALK BEHIND MOWER
10. Ensure that the steering control levers are
free to move and not in the latched position.
11. Remove the clevis pin from the LH pump
control spring cartridge and ensure that the
cartridge does not impede the movement of
the speed shaft.
12. Ensure that the speed control lever is in the
neutral position and loosen both jam nuts at
the turnbuckle of the speed control rod.
Rotate the speed shaft lever
counterclockwise until a significant
resistance is encountered, this will place the
RH pump in the neutral position. While
holding the speed shaft lever in position,
use the turnbuckle to adjust the length of
the speed control rod so that the bolt is
allowed to be installed freely, then secure
with the Nylok nut and tighten both jam nuts
at the turnbuckle.
13. Grasp the LH pump control spring cartridge
and pull rearward until a significant
resistance is encountered, this will place the
LH pump in the neutral position. Turn the
adjusting knob located at the rear of the LH
speed control spring cartridge until the
clevis pin is allowed to be installed freely,
then secure the clevis pin with the hairpin
cotter pin.
14. Make a visual inspection to ensure that the
steering control rods are free and do not
make contact with any other part of the
machine throughout their entire range of
motion at all speed settings. All
interference, if any, must be eliminated
immediately.
Caution - If the steering control rods are
allowed to touch another object it will adversely
affect the steering accuracy which may cause
the operator to lose control.
15. Place the speed control lever in the neutral
position and adjust the length of the steering
control rods by loosening the jam nuts and
turning each of the rods until the neutral
lock can be engaged, then tighten the jam
nuts.
FINAL
CHECK/ADJUSTMENT
Caution - It is highly recommended that after
making the above speed control adjustments
the initial start of the machine is done with the
rear wheels off the ground so that they are
allowed to rotate freely without the possibility of
propelling the machine.
1. At this point, check the engine oil level and
adjust as required. Make sure that the air
pressure in both rear tires is set at 12 psi,
tracking will be adversely affected if they are
not the same. Adjust the front tire
pressures to 20 psi.
2. Start the machine, release the park brake,
and set the throttle to allow the engine to
idle, the drive wheels should not be rotating.
Note - If the RH wheel is rotating an adjustment
is necessary to the length of the speed control
rod. If the LH wheel is rotating an adjustment
can be made with the adjusting knob located at
the rear of the speed control spring cartridge.
Always make any necessary adjustment to the
RH side first.
Caution - Do not adjust the nut at the rear of the
RH pump control spring cartridge, this is set at
the factory. If an inadvertent adjustment has
been made, remove the clevis pin from the
pump control spring cartridge and set the gap to
between 1 and 3 millimeters as shown in fig. 2.
