Checking and Adjusting the
Traction Linkage
Due to normal wear in the control linkage and hydrostatic
transmission, an increased amount of force may be required
to return the transmissions to neutral. Periodically check
the machine.
1. Park machine on a level surface, lower cutting units to
the floor and shut engine off.
2. Connect brake pedals together with locking pin, push
both pedals down and pull parking brake latch out.
3. Loosen outer hex nut securing eye bolt to spring anchor
plate (Fig. 65).

5. Shorten distance to
decrease time required to
stop machine.
4. Rotate clockwise until distance between inside of eye
bolt loop and inside of spring anchor plate is shortened
1/8 in., as shown in Figure 65. Tighten hex nut.
5. Operate the machine and check stopping distance.
Repeat procedure if required.
Note: Shortening the distance between inside of eye bolt
loop and inside of spring anchor plate increases the pedal
force on the traction pedal. Therefore, do not over adjust.
Adjusting the Service Brakes
Adjust the service brakes when there is more than 1 inch of
“free travel” of the brake pedal, or when the brakes do not
work effectively. Free travel is the distance the brake pedal
moves before braking resistance is felt.
1. Disengage locking pin from brake pedals so both pedals
work independently of each other.
2. To reduce free travel of brake pedals, tighten the brakes
by loosening the front nut on threaded end of brake
cable (Fig. 66). Then tighten rear nut to move cable
backward until brake pedals have 1/2 to 1 inch of free
travel. Tighten front nuts after brakes are adjusted
correctly.

Changing the Transmission
Fluid
Change the transmission fluid after every 800 hours of
operation, in normal conditions.
1. Position machine on a level surface, lower the cutting
units, stop the engine, engage the parking brakes, and
remove key from ignition switch.
2. Clean area around suction line on bottom of
transmission (Fig. 67). Place drain pan under line.
3. Remove line from transmission allowing fluid to drain
into drain pan.
4. Install suction line to transmission.
5. Fill with oil; refer to Checking the Transmission Fluid,
page 21.
