MAINTENANCE

Deck has anti-scalp rollers.
Anti-scalp rollers are properly adjusted when they are 

just slightly off of the ground when the deck is at the 

desired cutting height in the operating position. Anti-

scalp rollers then keep the deck in the proper position 

to help prevent scalping in most terrain conditions.

Adjust the deck to the desired cutting height (see 

1. 

“To Adjust Deck Cutting Height” in the operation 

section of this manual).
Using a ¾" wrench and a

" wrench, remove the 

nut and shoulder bolt from the anti-scalp roller.
Lower the anti-scalp roller to the ground, and raise 

3. 

it up to the next highest hole.
Replace and tighten the nut and shoulder bolt.

4. 

Be sure to adjust all of the anti-scalp rollers to the 

5. 

same position.
Be sure to readjust the anti-scalp rollers if the 

6. 

cutting height is changed.

If the mower is not tracking straight, check the air 

pressure in both rear tires. Recommended air pressure 

is 15 psi (1 bar). If the unit will not track straight, follow 

the steps below. Tracking must be checked on a flat 

and level concrete or blacktop surface.
Mower is tracking to the right.
Increase the air pressure 2-3 psi (0.1-0.2 bar) in the 

right rear tire or decrease the air pressure 2/3 psi in 

the left rear tire.
Mower is tracking to the left.
Increase the air pressure 2-3 psi (0.1-0.2 bar) in the 

left rear tire or decrease the air pressure 2/3 psi in the 

right rear tire.
Recheck tracking and keep making adjustments with 

the tire pressure until the unit tracks straight.
DO NOT exceed maximum recommended tire 

pressure 24 psi (1.6 bar).
Record the tire pressure for future reference.

Purging Procedure
Due to the effects air has on efficiency in hydrostatic 

drives, it is critical that it is purged from the system.
Purge procedures should be done any time a 

hydrostatic system has been opened for maintenance 

or for adding oil to the system.
Symptoms in hydrostatic systems may be:

Noisy operation.

1. 

Lack of power or drive after short term operation.

2. 

High operation temperature.

3. 
Before starting, make sure the transaxle/transmission 

is at the proper oil level.
Procedures should be performed with the machine 

drive wheels off the ground, then repeated under 

normal operating conditions.

With the bypass valve 

1. 

open and the engine 

running, slowly move the directional control in both 

forward and.reverse directions (5 or 6 times). As 

air is purged, the oil level will drop.
With the bypass valve 

2. 

closed and the engine 

running, slowly move the directional control in 

both forward and reverse directions (5 to 6 times). 

Check the oil level, and add oil as required after 

stopping the engine.
It may be necessary to repeat Steps 1 and 2 until 

3. 

all the air is completely purged from the system. 

Purging is complete when the transaxle moves 

forward and in reverse at normal speed.
