SECTION 2
OPERATION
DANGER
To prevent injury to bystanders, this mower is
not intended for roadside or municipal mowing.
This mower is intended for agricultural use only.
Failure to comply will result in death or serious
injury.
WARNING
Disengage the PTO, turn off the tractor engine
and remove the key. Wait for all movement to
stop before leaving the operator’s position.
Never adjust, lubricate, clean or unplug machine
with the engine running. Failure to comply could
result in death or serious injury.
WARNING
A tractor with an enclosed cab is required when
operating a rotary disc cutting machine. Failure
to comply could result in death or serious injury.
After the 600 Series disc mower has been lubricated,
attached to the tractor, and adjusted correctly, it is
ready for field operation. Refer to other sections of
this manual for the above information.
Lower the cutter bar onto the ground and position the
tractor hydraulic valve in the “Float” position. Ensure
that the up-stop channel is positioned over the lift
cylinder rod, and the cutter bar curtain is folded
forward over the cutter bar. Refer to the “General
Information” section of this manual for further
information.
WARNING
Never operate the mower with the curtain folded
rearward in the transport position. Failure to
comply could result in death or serious injury.
IMPORTANT: Do not engage the PTO with the
tractor running at high speed or the mower driveline
may be damaged.
Slowly engage the PTO before the unit is moved up
to the standing material. Be sure the tractor PTO is
running at 540 RPM before starting to cut.
IMPORTANT: Operating at excessive PTO speeds
will shorten the machine life and cause structural
failure.
WARNING
Loose stones and foreign objects can be
deflected toward the operator on machines with
rotary discs. Keep all curtains and shields in
place. Failure to comply could result in death or
serious injury.
OPENING FIELDS
Fields can be opened the same way with a disc
mower as with sickle bar-type mowers by cutting the
back swath first; cut backwards around the field,
running the cutter bar along the edge of the field.
After the backswath is cut, reverse direction and cut
around the field in a clockwise direction; reduce
ground speed to pick up most of the crop run down
by the tractor tires on the backswath.
FIELD CUTTING
1. To cut square corners:
Start turning the tractor as the rear wheels
approach the edge of the standing crop; turn the
tractor sharply in order to keep the cutter bar in
the crop. Using the right wheel brake on the
tractor may allow a sharper turn, but may also
gouge the ground.
It may be necessary to slow the ground speed to
turn corners, although it is almost impossible to
make clean square corners. Corners will tend to
stretch out as cutting continues. This operation
will not cause plugging as with other types of
mowers.
After the field is cut, the corners may be cut out
by cutting from the center of the field to the
corners to mow any standing crop; the cutter bar
will not plug when cutting through previously cut
material.
