Operating Instructions

Parking Brake

The parking brake functions by locking a detent arm into the transaxle outer control gear teeth. Moving the lever FORWARD engages the parking brake; moving the lever BACKWARD releases the brake.

IMPORTANT: Stop the tractor completely before engaging the parking brake The parking brake uses a positive mechanical lock similar to the PARK position on an automotive automatic transmission. If the tractor is moving when the brake is engaged, it will result in sudden stoppage and possible internal damage to the transaxle.

NOTE: If pressure on the parking brake pin (e.g., parked on a hill) makes it impossible to release the parking brake with the parking brake lever, move the mower gently forward or backward to allow the brake detent to set into the teeth.

Transaxle Lockout Rods

The transaxle lockout rods disengage the transaxles. By lifting the rods up and locking them into place with the shoulder on the rod in the chassis notch, the transaxles are released to permit freewheeling. By releasing the rods and recessing them back toward the chassis, the transaxles are engaged for normal operation. The transaxle rods in the LOCKOUT position are used to enable moving the machine without the engine running (e.g., for service). Refer to TRANSAXLE LOCKOUTS in this section for operating instructions.

NOTE: The transaxle lockout rods ends should be completely retracted against the body, otherwise operation of the transaxle may be erratic.

Hydro Lockout



The hourmeter, which is located on the right front of the body, displays operating time accumulated when the PTO is in the ENGAGED position.

The hourmeter provides maintenance reminders after certain hours of operation. The hourmeter screen will start flashing the reminder one hour prior to the recommended interval and will continue until one hour after the recommended interval (two hours).

The hourmeter does not have a manual reset function.

* These intervals reflect the actual time that the reminder will flash (one hour prior to and one hour after the recommended interval).

** This reminder is only used one time.

*** In normal operating conditions, oil changes in

100-hour intervals are acceptable. Walker and the engine manufacturers recommend engine oil changes every 50 hours in extremely dirty or dusty conditions or for units with less than 100 hours annual use.

NOTE: The blinking hour glass on the display means that the meter is operating properly.
