CAUTION: This vehicle is equipped with a Power Take-Off. Shut engine off before working on the Power Take-Off
or getting below the vehicle. Consult the operating instructions before using the PTO. (See sun visor.)
POWER TAKE-OFF OPERATION — VEHICLE STATIONARY
Automatic Transmission with PowerShift PTOs
Engage the PTO with the engine at idle speed.
NOTe: PowerShift PTOs: The engine must be at idle or below 1000 RPM when the PTO is engaged. See the
transmission manufacturer’s instructions for special procedures.
IMPORTANT:
Failure to follow the proper shifting or operating sequences will result in premature PTO failure with
possible damage to other equipment.
Warning: Cold Weather Operation of PowerShift PTOs
During extreme cold weather operation [32° F (0° C) and lower], a disengaged PowerShift Power Take-Off can
momentarily transmit high torque that will cause unexpected output shaft rotation. This is caused by the high
viscosity of the transmission oil when it is extremely cold. As slippage occurs between the Power Take-Off clutch
plates, the oil will rapidly heat up and the viscous drag quickly decreases.
The Power Take-Off output shaft rotation could cause unexpected movement of the driven equipment, resulting
in serious personal injury, death, or equipment damage.
To avoid personal injury or equipment damage:
■
Driven equipment must have separate controls.
■
Driven equipment must be left in the disengaged position when not in operation.
■
Driven equipment must not be operated until the vehicle is allowed to warm up.
