BEFORE OPERATING: Make sure there is nothing under the cutter (tools, feet, hands, etc.) that should not be there.
Check to make sure all parts are assembled correctly. Set tractor lift control stop at a position that will prevent the drive
shaft from contacting the front edge of the cutter when cutter is at full lift. (On some tractors, this won’t be necessary.)
The cutter should only be engaged with the tractor PTO shaft when the tractor engine is at idle speed.
Engaging the cutter at higher engine speeds will shorten the life of the cutter drive line. This may also damage the tractor.
For most cutting, ground speed of 3 to 5 MPH and a PTO speed of 540 RPM is recommended. However, you may wish to
adjust ground speeds for specic conditions.
After using the cutter for a full day, check the stumpjumper to make sure it is tight on the output shaft. If loose, torque the
nut holding it at 350 ft-lbs of torque. Replace cotter key through output shaft to secure nut.
Check blade pivot bolts and blade carrier nuts frequently for looseness or wear. Loose blades can easily pierce a ¼” steel
plate, and cause serious injury or death.
We recommend purchasing and properly installing chain guards with your rotary cutter. Make sure safety chain shielding
and gearbox shields are in place at all times.
