4. OPERATION
Transporting
NOTE: Always disengage PTO before raising mower to transport position.
1. When raising the mower to transport position, be sure that driveline does not contact tractor or mower. Adjust
and set the tractor’s 3-point hitch lift height so that the driveline does not contact mower deck in the fully
raised position.
2. Be sure to reduce tractor ground speed when turning, leaving enough clearance so that the mower 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 for adequate
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 mower blades.
2. Grass is best cut when it is dry. Mowing wet grass can cause plugging resulting in grass clumps behind the
mower.
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 mower, 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 mower 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 mower 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. Mower 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 mower is adjusted properly.
12. Do not make sharp turns or attempt to back up while mower is on the ground.
13. Do not engage PTO with mower in the fully raised position. Do not engage PTO at full throttle.

5. ADJUSTMENTS
Leveling the Mower
NOTE: Tractor and mower 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 mower 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 mower 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 height adjustments!
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 flail mower. 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. Excessive tension on the
belt may also lead to a safety hazard to the operator or bystanders.

6. MAINTENANCE
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
For safety reasons, each maintenance operation must be performed with tractor PTO disengaged, mower lowered
completely to ground and tractor engine shut off with ignition key removed.
After using the mower for several hours, check all bolts to be sure they are tight and check drive belt tension.
Replace any worn, damaged or illegible safety decals by obtaining new decals from dealer.
Knife Replacement
IMPORTANT
Make sure that the knife is the same length as the others on the mower. This will keep the rotor rotation balanced.
1. Remove bolt and nut.
2. Remove old knife.
3. Install new knife and existing bolt.
4. Secure with nut.
V-Belt Installation
CAUTION
Belt drive system under spring tension; use care to avoid bodily harm!
1. Remove belt guard fender and belt cover.
2. Disengage belt tension by loosening belt tension bolt until belt can be removed.
3. With tension relieved from belt remove old belt from pulleys.
4. Tighten belt tension bolt.
5. Reinstall belt guard and belt guard fender.
Storage
At the end of the working season or when the mower will not be used for a long period, it is good practice to clean
off any dirt or grease that may have accumulated on the mower and any of moving parts.
1. Clean as necessary.
2. Check knives for wear and replace if necessary.
3. Inspect mower for loose, damaged or worn parts and adjust or replace as needed.
4. Store unit inside if possible for longer life.
5. Repaint parts where paint is worn or scratched to prevent rust.
6. Replace all damaged or missing decals.
