Operating Instructions26Parking BrakeThe parking brake functions by locking a detent arminto the transaxle outer control gear teeth. Movingthe lever BACKWARD engages the parking brake;moving the lever FORWARD releases the brake.IMPORTANT: Stop the tractor completely beforeengaging the parking brake. The parking brake usesa positive mechanical lock similar to the PARK posi-tion on an automotive automatic transmission. If thetractor is moving when the brake is engaged, it willresult in sudden stoppage and possible internaldamage to the transaxle.NOTE: If pressure on the parking brake pin (e.g.parked on a hill) makes it impossible to release theparking brake with the parking brake lever, move themower gently forward or backward to allow the brakedetent to set into the teeth.Transaxle Lockout RodsThe transaxle lockout rods disengage the transax-les. By lifting the rods up and locking them into placewith the shoulder on the rod in the chassis notch, thetransaxles are released to permit freewheeling. Byreleasing the rods and recessing them back towardthe chassis, the transaxles are engaged for normaloperation. The transaxle rods in the LOCKOUTposition are used to enable moving the machinewithout the engine running (e.g., for service). Referto TRANSAXLE LOCKOUTS in this section foroperating instructions.NOTE: The transaxle lockout rods ends should becompletely retracted against the body, otherwiseoperation of the transaxle may be erratic.Hydro Lockout Rod LocationHourmeterThe hourmeter, which is located on the left front ofthe body, displays operating time accumulatedwhile the ignition switch is in the ON position.The hourmeter provides maintenance remindersafter certain hours of operation. The hourmeterscreen will start flashing the reminder one hour priorto the recommended interval and will continue untilone hour after the recommended interval (twohours). The hourmeter does not have a manualreset function.* These intervals reflect the actual time that thereminder will flash (one hour prior to and onehour after the recommended interval).** This reminder is only used one time.*** In normal operating conditions, oil changes in100-hour intervals are acceptable. Walker andthe engine manufacturers recommend engineoil changes every 50 hours in extremely dirtyor dusty conditions or for units with less than100 hours annual use.NOTE: The blinking hour glass on the displaymeans that the meter is operating properly.HourmeterHydro LockoutRodsProcedure Interval* ReminderOil Change(Break-In)** 4-6 Hours CHGOILLubricateand CheckLevels24-26 Hours LUBEOil Change 49-51 Hours*** CHGOIL
