SECTION 00 -- GENERAL INFORMATION -- CHAPTER 2
00-2
DANGER
To prevent injury to bystanders, this mower is
not intended for roadside or municipal mowing.
This mower is intended for agricultural use only.
CAUTION
A tractor with an enclosed cab is recommended
when operating a rotary disc cutting machine.
After the disc mower has been lubricated, attached
to the tractor, and adjusted correctly, it is ready for
field operation. Refer to the 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 cyl-
inder 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 he transport position.
IMPORTANT: Do not engage the PTO with the trac-
tor 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 fail-
ure.
CAUTION
Loose stones and foreign objects can be de-
flected toward the operator on machines with
rotary discs.
OPENING FIELDS
Fields can be opened the same way with a disc mow-
er 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 ap-
proach 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 trac-
tor 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 cor-
ners to mow any standing crop; the cutter bar will
not plug when cutting through previously cut ma-
terial.
2. To cut oversquare corners:
Continue cutting in forward direction until the cut-
ter bar approaches the end of the corner; turn the
tractor sharply to the right, leaving the cutter bar
on the ground to finish cutting the corner.
The cutter bar can be left on the ground while
traveling back to the standing crop; the cutter bar
will not plug when cutting through previously cut
material.
NOTE: Maintain full PTO speed when crossing pre-
viously cut material, even if the cutter bar is raised off
the ground. Failure to do so may cause cutter bar
wrappage and plugging.
