Two or more workers should attach and detach this machine since it is very heavy.
6-2. Method of Attaching The Machine
1.Place the machine on a flat, stable location.
2.Move the tractor backward to the machine and align the center position of the machine’s
linkage section.
3.Raise and lower the lower links with the tractor’s lift lever to align them with the link pin
position.
4.Apply the tractor’s parking brake and stop the engine.
5.Chock the tractor.
6.Attach the left lower link and lock the link pin.
7.Raise and lower the lower link with the leveling handle on the right lift link to align it with
the pin position.

Do not forcibly insert the universal joint with a hammer etc.
It may cause the joint breakage.
9.Shorten the joint to the highest possible
extent and attach it if the clearance
between the joint tip and the tractor's PTO
shaft is approximately 10 mm.
*Make sure that the lock pin head projects
more than 10 mm.
*Make sure that the lock pin is precisely in
meshing engagement with the shaft groove.
If there is not that clearance, cut off the
excessive portion of universal joint.
10.Attach the chain for stopping protective cover rotation on the lower link hook.
11.Make sure that the machine is not equipped with tines.
12.Start the engine of the tractor.
13.Make sure that there is no abnormal noise in the universal joint and the machine when
rotating PTO shaft with the machine lowered (or with the front roller in contact with the
ground).

6-4. Method of Cutting Universal Joint
Work with great caution when using a high speed cutter.
The universal joint length depends on the type of tractor to be linked.
1.Hold the half shafts of universal joint next to
each other in the shortest working position
between the tractor and machine, and mark
them.
2.Cut the inner and outer guard tubes at the
marked positions.
3.Mark the shaft at the same length from its
tip as the removed guard tube.

7．Inspections
7-1. Precautions before Inspection
Read “Inspection before work” on the tractor’s owner’s operating manual carefully.
Be sure to stop the engine before inspection, service and adjustment with the tractor
linked.
7-2. Inspection of Covers
If you have removed a protective cover during inspection, be sure to securely install it in
its original position.
If a protective cover remains removed, foreign objects may fly off, possibly resulting in
injuries.
● Make sure that there is no wear or deterioration of protective covers.
● Make sure that there is no damage to protective covers.
● Make sure that there is no interference with moving parts due to deformation of protective
covers.
● Make sure that protective covers are installed in their appropriate positions.
7-3. Inspection of Rollers
Bearing wear due to frequent use or bearing damage caused by water infiltration may
prevent the roller from rotating smoothly.
Inspect the roller and, if necessary, replace parts such as oil seals and bearings.
1.Make sure that there is no abrasion nor adhesion of the roller.
2.Make sure that there is no wear of the roller shaft.
3.Make sure that there is no wear nor damage of the oil seal.
4.Make sure that there is no wear nor rust of the bearing.
5.Make sure that there is no play in the roller shaft.
7-4. Inspection of Tines
Wear gloves when touching tines to avoid cutting your hands.
Vibration from imbalance, dullness or poor discharge of cores may occur due to frequent use
or damage during transportation.
Inspect and, if necessary, replace.
1.Make sure that the tines are not bent.
2.Make sure that the tines are not chipped.
3.Check how much the tines are worn.
The operating depth cannot be maintained if tine wear is 10 mm (0.39 in) or more.
4.Make sure that the edges of tines are not too blunt, making cutting difficult.
5.Make sure that the mounting bolts for the tines are not loose.
6.Check how much the sliding plate of the tine mount section is worn.
7-5. Inspection of Lawn Pressing Plate
Damage may occur due to frequent use or during transportation.
Inspect and, if necessary, replace.
1.Make sure that there is no deformation of the lawn pressing plate.
2.Make sure that there are no cracks or damage to the lawn pressing plate.
3.Make sure that the mounting bolts for the lawn pressing plate are not loose.

The oil gauge is located on the side of the gear
box.
1.On a level surface, check that the oil level
reaches the middle of the oil gauge.
2.Check underneath the machine for oil
leakage.
7-7. Supply of Gear Oil
Do not mix different types of oil.
Use BONNOC TS680 (or equivalent) as oil.
1.If the oil level is low, follow the steps below to supply oil.
[1]Open the oil filler cap, and then supply oil through the oil filling port until the oil level
reaches the middle of the oil gauge.
[2]Tighten the oil filler cap securely.
2.On a level surface, check if the oil level is at
the middle of the oil gauge. If necessary,
supply oil.
3.Check underneath the machine for oil
leakage.
7-8. Inspection of Universal Joint
1.Inspect the chain for damage, abnormal wear and so on.
2.Inspect the cover for cracks, damage, abnormal wear and so on.
