c. Locate jam nuts. (Reference control

assembly in parts list).

d. Loosen jam nuts on both ends of rod con-

nectors. See Control Assembly in the Illus-

trated Parts Book (ONLY if mower creeps.)

e. Start unit and push throttle all the way on.

f. If unit creeps forward rotate rear rod con-

nectors counter-clockwise. And if unit

creeps in reverse, rotate clockwise.

Adjust the appropriate rod connector. The

left rod for the left side of the mower and

the right rod for the right side of mower.

Afterward, retighten jam nuts.

E. Brakes

While the mower is in motion, all braking is performed

dynamically through the hydraulic pumps and traction

motors, controlled by the two steering levers. When the

mower is parked with the engine shut off, the hydraulic

system locks the traction wheels.

Note:

To move the mower forward or in

reverse by pushing, you must release the

dynamic braking. Locate the valves on the

pump. Turn valves counter-clockwise one

quarter turn to push the unit. After pushing

the mower to the desired location, return both

valves to the operating position (See photo

below)

When the mower is parked with the engine running

and the steering levers opened out in the neutral

position, the parking brakes should be applied. The

parking brakes are drum-type brakes mounted on

each traction wheel.They are both engaged by the

same operating lever.

Adjustments:

The parking brake handle is an

overcenter lever that should engage with

moderate force.

Note:

To increase parking brake capacity

tighten the brake rods going back to the brake

arms equally. Tighten rods one full turn and

check parking capacity. Repeat Step.

To adjust either brake individually, tighten the hex nut

in a clockwise direction one full turn looking down the

brake rod. This will tighten the brake about .040 inch.

Normally, both brakes should be adjusted and equal

amount.

Repair:

The mower is equipped with drum

brakes and will not normally require mainte-

nance. If they are not working properly, please

contact your service center.

F. Hydraulic System

Hoses:

Check the hoses from the hydraulic

oil tank to the oil filter to the hydraulic lines

daily for leaks or abrasion and replace any

damaged hoses. Make certain there are no

kinks or twists in any hose.

Hydraulic Oil Tank and Filter:

Note:

Change the hydraulic oil and the oil

filter after the first 500 hours of operation and

every 500 hours thereafter.

To drain the hydraulic oil tank, place a 2 gallon drain

pan under the drain plug on the bottom of the

hydraulic oil tank. Remove the drain plug, drain the

tank, then replace the plug. Place the drain pan under

the filter and remove the filter by unscrewing in a

counterclockwise direction. The filter will be full of oil,

so empty it into the drain pan. You don’t have to drain

the rest of the hydraulic system. Fill the replacement

filter with a good grade of 5W40 Synthetic oil and

lubricate the sealing surface. Screw the filter onto the

filter base until it seats and then another one-half turn

to seal.

Note:

Always wipe off the hydraulic tank fill

cap and the area around it before removing the

cap to prevent dirt from contaminating the oil.

Remove the fill cap and fill the tank with the same

5W40 Synthetic oil selected for the filter until the oil

level is up to the level of the second hole in the fill

tube. Leave this air space for expansion. Start the

engine and let it run at idle for about five minutes.

Check the filter for leaks. Idling the engine and the

pumps in this way will purge any air from the system.

Shut off the engine and recheck the oil level in the

tank. Top-off if necessary until the oil level is up to the

second hole in the fill tube.

Note:

After unit is up to operating tempera-

ture, turn off engine and re-check hydraulic

oil. If oil appears foamy or contains excessive

air bubbles, DO NOT OPERATE UNIT. Contact

service technician.

Hydrostatic Pumps and Motors:

The pumps

are the hardest-working components in the

hydraulic system. They are in operation all the
