Adjusting the Traction Pedal

To check the forward and reverse operation of the traction

pedal, proceed as follows:

Adjusting Forward

1.

Press the traction pedal fully forward until the No. 5

section valve spool is completely pulled out. The pedal

should contact the pedal stop (Fig. 48).

If the pedal contacts the stop before the spool is

completely out, or if the pedal does not make contact

with the stop, an adjustment to the stop is necessary.

Proceed as follows:

2.

Loosen the hex nut securing the threaded rod to the

frame. Turn the flange nut on the rod to raise or lower

the stop (rod) while checking the pedal. Retighten the

nut.

Adjusting Reverse

1.

Press down on the rear of the traction pedal (reverse)

until the No. 5 section spool valve is completely pushed

in.

2.

Check the distance between the bottom of the pedal and

footrest as shown in Fig. 48. The distance shouId be

approximately 3/16 in. (5 mm). If the distance is greater

or less than 3/16 in. (5 mm), an adjustment to the

traction control rod is required. Proceed as follows:

A. Remove the jam nut and ball joint securing the

control rod (Fig. 48) to the traction shaft pivot.

B. Loosen the jam nuts securing the ball joints to the

control rod and adjust the ball joints and control rod

to attain the 3/16 in. (5 mm) dimension when

reinstalled.

Adjusting Cutting Unit Lift and

Drop

The cutting unit lift/drop circuit is equipped with a flow

control valve. This valve is preset at the factory at

approximately 3-1/2 turns open, but an adjustment may be

required to compensate for differences in hydraulic oil

temperatures, mowing speeds, etc. If an adjustment is

required, proceed as follows:

Note:

 Allow the hydraulic oil to reach full operating

temperature before adjusting the flow control valve.

1.

Raise the seat and locate the flow control valve

mounted to the main control valve (Fig. 49).

2.

Loosen the jam nut retaining the adjusting knob on the

flow control. When loosening the jam nut, 

hold the

flow control knob

 to prevent it from rotating.

3.

Rotate the knob 1/4 turn counterclockwise if the center

cutting unit is dropping too late or 1/4 turn clockwise if

the center cutting unit is dropping too early. 

4.

After the desired setting has been achieved, hold the

knob to prevent any rotation and tighten the jam nut.

Adjusting the Lift Cylinders

To regulate the height of the front cutting units when in the

raised (transport) position, the front lift cylinders may be

adjusted.

1.

Lower the cutting units to the ground.

2.

Loosen the jam nut, on the clevis, of the cutting unit lift

cylinder that needs to be adjusted.

3.

Disconnect the cylinder clevis from the lift arm.

4.

Rotate the clevis until the desired height is attained.

5.

Connect the cylinder clevis to the lift arm and tighten

the jam nut.
