Your tractor’s transmission is equipped with a hydrostatic 

relief valve for occasions when it is necessary to move the 

tractor manually. Opening this valve permits the fluid in the 

transmission to bypass its normal route, allowing the rear tires 

to “freewheel.” To open the hydrostatic relief valve, proceed as 

follows:

Locate the hydrostatic bypass rod in the rear of the tractor. 

1. 

See Fig. 3-1.

Pull the hydrostatic bypass rod outward, then down, to lock it in 

2. 

place.

NOTE: The transmission will NOT engage when the hydrostatic 

bypass rod is pulled out. Return the rod to its normal position 

prior to operating the tractor.

Never attempt to move the tractor 

manually without first opening the hydrostatic relief 

valve. Doing so will result in serious damage to the 

tractor’s transmission. 

Make sure the lawn tractor’s engine is 

off, set the parking brake and remove the ignition 

key before removing the shipping brace.

Locate the shipping brace, if present, and warning tag 

1. 

found on the right side of the cutting deck. See Fig. 3-2.

While holding the discharge chute with your left hand, remove 

2. 

the shipping brace with your right hand by grasping it 

between your thumb and index finger and rotating it 

clockwise.

The shipping brace is used for 

packaging purposes only. Remove and discard the 

shipping brace before operating your lawn tractor.

The mowing deck is capable of 

throwing objects. Failure to operate the riding 

mower without the discharge cover in the proper 

operating position could result in serious personal 

injury and/or property damage.
