Section 2: Operating Instructions
Transporting
NOTE: Always disengage PTO before raising rotary cutter to transport position.
1. When raising the rotary cutter to transport position, be sure that driveline does not contact tractor or rotary cutter. Adjust
and set the tractor’s 3-point hitch lift height so that the driveline does not contact rotary cutter deck in the fully raised
position.
2. Be sure to reduce tractor ground speed when turning, leaving enough clearance so that the rotary cutter does not contact
obstacles such as buildings, trees or fences.
3. Select a safe ground travel speed when transporting from one area to another. When traveling on roadways, transport in
such a way that faster moving vehicles may pass safely.
4. When traveling over rough or hilly terrain, shift tractor to a lower gear.
CAUTION
When traveling on public roads, whether at night or during the day, use accessory lights and devices foradequate warning to
operators of other vehicles. Comply with all Federal, State, and local laws.
Mowing Instructions
1. Clear area to be mowed of objects and debris that might be picked up and thrown by the rotary cutter blades.
2. Grass is best cut when it is dry. Mowing wet grass can cause plugging resulting in grass clumps behind the rotary cutter.
3. Grass should be mowed frequently as shorter clippings deteriorate faster.
4. If mowing extremely tall grass, it is best to raise cutting height and mow the area, then lower cutting height and mow a
second time at the desired height.
Operating Instructions
Proper servicing and adjustments are the key to the long life of any machine. With careful and systematic inspection of the rotary
cutter, costly maintenance, time and repair can be avoided.
Before beginning to mow, the following inspection should be performed:
1. Check oil level in gearbox.
2. Check that all plugs in gearbox have been replaced and tightened properly.
3. Be sure all rotary cutter knives, bolts and nuts are tight.
4. Be certain all guards and shields are in place and secure.
5. Grease driveline shaft and all other grease fittings.
6. Clear area to be mowed of rocks, branches and other foreign objects.
7. Lower rotary cutter to ground. Set tractor throttle at approximately 1/4 open. Engage PTO to start blades rotating.
8. Operate with 540 rpm PTO tractor.
9. At first begin mowing at a slow forward speed and shift up until the desired speed is achieved - maintaining 540 PTO rpm.
10. Rotary cutter knives will cut better at a faster blade speed than at reduced throttle.
11. After mowing the first 50 feet, stop and check to see that the rotary cutter is adjusted properly.
12. Do not make sharp turns or attempt to back up while rotary cutter is on the ground.
13. Do not engage PTO with rotary cutter in the fully raised position. Do not engage PTO at full throttle.

Section 3: Adjustments
Leveling the Rotary cutter
NOTE: Tractor and rotary cutter should be on level ground.
Leveling can be adjusted at the tractor’s 3-point arms and center link.
Cutting Height Adjustment
The machines cutting height depends upon the position of the rear roller.
1. Remove the bolts that fix the roller on both sides.
2. Lift or lower both sides of roller in equal measurements.
3. Replace bolts and re-tighten.
3-Point Hitch Adjustments
The 3-point hitch system on this rotary cutter has been designed for front to back flotation when mowing on uneven terrain. Adjust
tractor’s top center link to place the upper hitch pin vertically above or slightly behind the lower hitch pins. The rotary cutter should be
run with the back 15 degrees lower than the front.
The hitch can also be adjusted from side to side by turning the adjustment handle. Turn handle until you have achieved your desired
location.
CAUTION
Engage parking brake, shut off tractor, remove key and disengage PTO before making any heightadjustments!
Belt Tension
CAUTION
Belt drive system under spring tension; use care to avoid bodily harm!
The Belt tension should be checked after the first 20 hours of use. And then every 40 hours of use.
1. Tension on the belt can be adjusted with the belt tension bolt. Turn the bolt until desired tension is achieved. When the
belt has the correct tension the gearbox should be adjusted so that the gearbox extension is running straight (parallel)
with the Rotary Cutter. Loosen bolts at the bottom of the gearbox and move gearbox until gearbox extension is running
straight.
2. Excessive tension on the belt may lead to premature failure of belt and drive components.
CAUTION
Excessive tension on the belt may lead to premature failure of belt and drive components. Excessivetension on the belt
may also lead to a safety hazard to the operator or bystanders.
Section 4: Maintenance and Lubrication
Maintenance
Proper servicing and adjustment is the key to the long life of any farm implement. With careful and systematic inspection, you can
avoid costly maintenance, time and repair.
CAUTION
