Installation Instructions
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 P.T.O.
(See sun visor.)
POWER TAKE-OFF OPERATION — VEHICLE STATIONARY
Automatic Transmission with Powershift P.T.O.s
Engage the P.T.O. with the engine at idle speed.
NOTE: Powershift P.T.O.s: The engine must be at idle or below 1000 R.P.M. when the P.T.O. is en-
gaged. See the transmission manufacturer’s instructions for special procedures.
IMPORTANT:
Failure to follow the proper shifting or operating sequences will result in premature P.T.O.
failure with possible damage to other equipment.
Warning: Cold Weather Operation of Powershift P.T.O.s
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.
This symbol warns of possible personal injury.
