WARNING
Never operate the PTO pump without the tractor PTO shield in
place, and the pump torque bar firmly chained in place.
1. To operate a PTO pump, engage the PTO shaft
slowly at the tractor’s idle throttle position.
2. Slowly accelerate to the desired PTO RPM.
• On a 540 RPM pump, the RPM of the PTO would
be the speed at which the dead head pressure
reaches 80 PSI or 540 RPM.
• On a 1000 RPM pump, the RPM of the PTO would
be the speed at which the dead head pressure
reaches 80 PSI or 1000 RPM.
Operating Hydraulic Pump
1. To operate the hydraulic pump, first make sure that
the hydraulic hoses are routed correctly so that the
pump turns in the correct direction. See “Hydraulic
Pump Hook Up” on page 15.
2. To run the pump, push the hydraulic lever in the
“down” position.
3. When stopping the pump, push the hydraulic lever to
the “float” position.
Note: Do not move the hydraulic lever to the neutral posi-
tion while the hydraulic pump is running. To do so
may cause damage to the hydraulic pump.
