Operating Instructions27Transmission Lockout LeversThe transmission lockout levers disengage the hy-drostatic transmissions. By lifting the lever on topof the transmission and locking it into place with thelockout cam, the hydrostatic transmissions are re-leased to permit freewheeling. By releasing the camand lowering the lever, the transmissions are en-gaged for normal operation. The transmission leverin the LOCKOUT position is used to enable movingthe machine without the engine running (e.g., forservice). Refer to TRANSMISSION LOCKOUT inthis section for operating instructions.NOTE: The transmission plunger on the side of thetransmission case (activated by the LOCKOUT LE-VER) must be completely released during operationof the mower, otherwise operation of the transmis-sion will be erratic.LockoutLeversTransmissionPlungerLockout Lever 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 reminders af-ter certain hours of operation.
