Typical PTO Drive Gear And Mounting Pad

• If the power takeoff will be operated while the vehicle is stopped, set the

parking brake, shift the transmission to N (Neutral), and depress the

accelerator as required. Disengage the PTO after returning the engine speed to

idle and stopping the PTO-driven equipment.

• If the power takeoff will be operated while the vehicle is moving, simply

select the desired range and depress the accelerator as required. However, the

speed of the power takeoff during this type of operation will be affected by the

ranges selected and the speed of the vehicle.

• To disengage the power takeoff, stop the vehicle, idle the engine, and set the

brake. Place the shift selector in a drive range, stop the PTO-driven

equipment, and disengage the power takeoff. Return the transmission shift

selector to N (Neutral).

CAUTION: Never engage the PTO by clashing the gear teeth. This

may damage the PTO unit and the PTO drive gear teeth. Stop clash-

ing by releasing the vehicle brakes and allowing the vehicle to

move slightly or by moving the shift selector from a drive range to

N (Neutral) and back to a drive range.

CAUTION: Do not exceed the speed limits imposed on the driven

equipment during operation of the PTO.
