IMPORTANT SAFETY PRECAUTIONS
This symbol is used to call attention to safety precautions that should be followed by
the operator to avoid accidents. When you
see this symbol, carefully read the message
that follows and heed its advice. Failure to
comply with safety precautions could result
in serious bodily injury.
In addition to the design and configuration of equipment, hazard control and accident prevention are dependent upon the awareness, concern, prudence and proper training of personnel in the operation, transport,
maintenance and storage of equipment. Lack of attention to safety can result in accident, personal injury,
reduction of efficiency and worst of all—loss of life. Watch for safety hazards and correct deficiencies promptly. Use the following safety precautions as a general guide to safe operations when using this machine.
Additional safety precautions are used throughout this manual for specific operating and maintenance procedures. Read this manual and review the safety precautions often until you know the limitations.
1. Read the Operator’s Manual. Failure to read the Operator’s Manual is considered a misuse of this equipment.
2. Become familiar with all the machine’s controls and all the caution, warning and danger decals affixed
to the machine before attempting to start or operate.
3. Before starting or operating the machine, make a walk around inspection and check for obvious defects
such as loose mounting bolts and damaged components. Correct any deficiency before starting.
4. Do not allow children to operate the cutter. Do not allow adults to operate it without proper instruction.
5. Do not carry passengers.
6. Keep the area of operation clear of all persons, particularly small children and pets. The operator should
cease mowing whenever anyone comes within the operating area.
7. Clear the work area of objects which might be picked up and thrown.
8. Use a piece of cardboard or wood rather than hands to search for hydraulic leaks. Escaping hydraulic oil
under pressure can penetrate skin. If fluid is injected into the skin, it must be surgically removed within a
few hours by a doctor familiar with this form of injury or gangrene may result.
9. Do not operate without all guards and shields in place and in good condition.
10. Lower implement to ground, stop tractor engine, apply parking brake, and allow blades to completely
stop before leaving the tractor.
11. Keep hands and feet away from blades.
12. This cutter is not to be operated along highways or in any area where people may be present unless all
sides of the unit are enclosed by permanent bands, safety chains or other factory approved safety shields
that are in good repair.
13. Wear personal protective equipment such as, but not limited to, protection for eyes, ears, feet, hands and
head when operating or repairing the equipment. Do not wear loose clothing or jewelry that may catch on
equipment moving parts.
14. When performing adjustments or maintenance on the cutter, first lower it to the ground or block it securely
at a workable height.
15. Never stand between tractor and cutter while tractor is being backed to the cutter hitch.
16. Reduce speed when transporting cutter to avoid bouncing and momentary loss of steering.
17. Use tractor flashing warning lights, day or night, when transporting cutter on road or highways unless prohibited by law.
18. Stand clear of wing(s) when raising or lowering.
19. Purge air from hydraulic system before attempting to raise or lower wings.
20. In the event that someone other than yourself will operate this equipment we firmly suggest that all
SAFETY references be discussed prior to operation.
21. It is recommended that tractor be equipped with Rollover Protective System (ROPS) enclosed cab, and a
seat belt.

1-2 DESCRIPTION
The Model 2315 Rotary Cutter (Figure 1-1) consists
of a center unit with two variable position wings
together having a cutting width of 15 feet (4.5m).
Wing operating angles and machine cutting height
are independently controlled using hydraulic cylinders. A self-leveling linkage maintains a level cutter
at all cutting heights. Power from the tractor PTO is
split at the center gearbox and supplied to each of
the blade gearboxes. Each blade gearbox has two

free-swinging uplift blades designed for light mowing. Free-swinging blades reduce the shock of
impact when a stationary object is hit. Slip clutches
are installed on each gearbox for additional protection. Front and rear center discharge shields are
included as standard equipment. (Note: Dealer or
purchaser may elect to delete the front shields at
their option.) Machine specifications are given in

SECTION III
OPERATING INSTRUCTIONS
3-1 GENERAL SAFETY
Only qualified people should operate this machine.
Operator should wear hard hat, safety glasses and
safety shoes. It is recommended that tractor be
equipped with Rollover Protective System (ROPS)
and a seat belt be used. Before beginning operation, clear work area of objects that may be picked
up and thrown. Check for ditches, stumps, holes or
other obstacles that could upset tractor or damage
cutter. Always turn off tractor engine, set parking
brake, and allow cutter blades to come to a complete
stop before dismounting tractor.
3-2 TRANSPORTING
When implement is transported on road or highway,
day or night, use tractor flashing warning lights
unless prohibited by law. A slow moving vehicle
(SMV) sign must be visible from the rear by
approaching vehicles. A bracket for SMV sign is
provided on the center section shield. Do not
exceed 15 mph (24 kph) when traveling. Prepare
machine for transporting as follows:
A. Disengage tractor PTO.
B. Raise cutter and install stop collars on
height adjustment cylinder. (Figure 2-3)
C. Rotate cylinder stops away from wing cylin-
ders, raise wing(s) and insert transport lock pin(s).
3-3 OPERATION
A. Perform BEFORE EACH USE maintenance
listed in paragraph 4-1.
B. Make certain jackstand is stored for work.
C. Start tractor. Raise cutter and remove stop
collars. Remove wing transport lock pins and place
in storage hole (Figure 2-4). Lower wings to working
position. Raise/lower cutter to working height. The
cutter should be operated at the highest position that
will give desired cutting results. This will help prevent the blades from striking the ground, reducing
blade wear and undue strain on the whole machine.
Continuous ground and blade contact could force
blades into deck area.
D. Install stop collars on axle cylinder at desired
cutting height. Store remaining stop collars (if any)
Figure 2-5 Adjustable Link
around self-leveling linkage rod.
E. With tractor at idle speed, engage PTO drive.
IMPORTANT
DURING OPERATION THE HYDRAULIC VALVE
WING LEVERS MUST BE LOCKED IN THE FLOAT
POSITION TO AVOID DAMAGE TO THE CYLINDERS AND AXLES.
WARNING
IT IS HAZARDOUS TO OPERATE UNIT
WITH WINGS RAISED ABOVE GROUND.
DAMAGE CAN OCCUR TO WING DRIVELINE IF WINGS ARE OPERATED ABOVE 60°.
WARNING
KEEP CLEAR OF MACHINE WHEN
RAISING OR LOWERING WINGS. DO
NOT “DRIVE-OUT” TRANSPORT LOCK
PIN IF IT IS TIGHT AGAINST WING LUG.
TO REMOVE PIN, RETRACT WING LIFT
CYLINDER TO RELIEVE LOAD ON PIN.
DANGER
STAY CLEAR OF ROTATING DRIVELINES. DO NOT OPERATE WITHOUT
DRIVELINE SHIELDS IN PLACE AND IN
GOOD CONDITION. FAILURE TO HEED
THESE WARNINGS MAY RESULT IN
PERSONAL INJURY OR DEATH.
DANGER
ROTARY CUTTER BLADES. STAND WELL
CLEAR UNTIL ALL MOTION HAS STOPPED.
TO AVOID AN ACCIDENTAL FALL FROM
TRACTOR AND POSSIBLE INJURY BY
MOWER, IT IS RECOMMENDED THAT
TRACTOR BE EQUIPPED WITH ROLLOVER
PROTECTIVE SYSTEM (ROPS) AND A SEAT
BELT BE USED BY THE OPERATOR FOR
ALL MOWING OPERATIONS.
