CAUTION
Operational Hazard
Tractor PTO must operate
at 540 RPM only. Exceeding
the snow blower’s design
speed of 540 RPM will result in operator
injury or damage to the machine.

CAUTION
Operational Hazard
Personal Protection Equipment (PPE) is
required when operating or maintaining
this machine.
Attaching the Bush Hog power pack for the first time.
• Set the power pack on a level surface and back the tractor up to it. Place the
lower 3PH arms of the tractor between the lower hitch plates on the power pack
and insert the hitch pins that came with the power pack. Secure these with the
Lynch Pins.
• Next swing the top link into place and adjust the length so the top link pin can be inserted. You will have
to supply the top link pin. With the top link set at this length the power pack will be flat or parallel to the
ground. For optimum performance it is important that the power pack is level.
Do not fasten the PTO shaft to the tractor.
• Slowly lift the power pack until the gearbox shaft is at the same height as the PTO output on the tractor.
• Push (or collapse the telescopic part of the PTO completely). If you cannot collapse it far enough to slide
it on the tractor then it has to be shortened! (for more information see Sizing PTO Drive Line page)
• Make sure the plastic shield is free to rotate on the shaft before installing on the machine.
• Reinstall the PTO on the power pack, and fasten it to the tractor pushing the spring-loaded pin in and
sliding the yoke onto the tractor spline until the pin snaps into place.
• Make sure PTO does not bottom out at any point when lifting or lowering the power pack. PTO shaft
should not come within 2” of the yoke at any time.
• Lift and lower the 3PH arms to determine that the overlap on the PTO shaft is never less than 1/3 of the
shaft length if it is too short then the PTO will jam, rather than collapse. This will put severe strain on
the shaft and gearbox. It may come apart and this will allow a spinning PTO to become an uncontrolled
weapon and could severely injure or kill someone!
• After it has been determined that the PTO is OK and will not jam or come apart, slowly lift the power pack
until the gearbox shaft is at the same height as the PTO output on the tractor.
• Make sure any bystanders are well away from the machine.
• Lower the blower to ground level, engage the PTO and slowly start the blower. Make sure that every-
thing is turning freely.
• Slowly increase the speed until you have reached 540 RPM on the PTO. This is the speed that the
power pack was designed for. Running the power pack at greater RPM will cause damage to property
or personal injury.
