tractor and then back the tractor throttle off till the engine is at low idle. With the
tractor's rear hydraulic lift control lever, raise the mower to transport position
making sure that the PTO shaft is not in a bind and does not come in contact with
the mower frame. Lower the unit to cutting position and, with the tractor still at
low idle, engage the PTO. If everything is running smoothly at this point increase
the engine rpm until the tractor's engine reaches full PTO operating speed which
will be 540 rpm. Slowly raise the cutter to transport height to make sure the
driveline does not bind or chatter. Then return the engine to low idle, disengage
PTO, and position the adjustable stops on the tractor's hydraulic lift lever control
console so the cutter can be consistently returned to the same cutting and
transport height.
You should now be ready to move to the cutting site to begin working. You
should have inspected and should only be cutting in an area you are familiar with
which is relatively free of debris and unseen objects. Never assume an area is
clear. In the event you do strike an object, stop the tractor and mower
immediately to inspect the rotor and make any necessary repairs before
resuming operation. It pays to inspect a new area and to develop a plan before
you cut.
Normal working speed will be between 2-5 mph and you will need to maintain
tractor PTO speed to produce a clean cut so make a tractor gear and range
selection that will maintain this combination. Generally the quality of cut of will
be better at lower ground speeds and cutting denser ground cover or heavier
brush may create the need to slow down. Always cut downward on slopes and
avoid crossing the face of steep slopes. Avoid sharp drops and cross diagonally
through dips to prevent hanging up the tractor and mower. Slowdown in turns
and avoid sharp turns if possible. Remember to look back often.
Now you're prepared and well briefed so let's begin cutting. Reduce the tractor's
engine rpm, make sure the mower is on the ground and in cutting position,
engage the PTO, raise the engine rpm to the appropriate PTO speed, and begin
working. Operators must plan ahead and choose a cutting route that allows safe
turns. Try increasing or decreasing ground speed to determine the effect on
quality of cut. With a little practice you will be pleased with what you and your
mower can do.

CAUTION!
Engage parking brake, shut off tractor, remove key, and disengage PTO before
making any adjustments!
