Starting the tractor
the procedure to start the tractor is model specific. Refer to the tractor operator’s manual for starting
procedures for your particular tractor. consult an authorized dealer if the starting procedure is
unclear. ensure the 3-point control lever is in the lowered position and the PtO is disengaged before
starting the tractor.
Brake and differential lock Setting
make sure the tractor brakes are in good operating condition. tractor brakes can be set to operate
independently allowing single rear wheel braking action or locked together to provide simultaneous
rear wheel braking. FOR mOSt DRIVInG anD OPeRatInG COnDItIOnS, tHe BRaKe PeDaLS

always disengage the tractor differential lock when turning. When engaged the differential lock will
prevent or limit the tractor from turning. During normal cutting conditions, locking the differential
provides no benefit and should not be used.
Be aware of the operating conditions. Do not operate the tractor with weak or faulty brakes. When
operating down a hill or on wet or rain slick roads, the braking distance increases; use extreme
care and reduce your speed in these conditions. When operating in traffic, always use the tractor’s
flashing warning lights and reduce your speed. Be aware of traffic around you and watch out for the
other guy.
operating the cutter wings
Wings are positioned with hydraulic cylinders. It is recommended that the tractor be equipped
with three hydraulic ports or a 3-spool control valve be used so that each section can be controlled
independently. ensure the hydraulic cylinders and lines are filled with oil by holding the valve control
levers in the raised position until the cylinders fully retract (wings) and extend (center). Only operate
the cutter with both wings fully lowered, neVeR operate the cutter with a raised wing. Wait until the
blades are at a complete stop before raising wings.
