RPM
.
14. Before cleaning, repairing and lubricating the machine, stop the motor and take away
the key with you.
15. When the universal joint is not connected with the tractor, they must be connected
again through the frame to protect the joint from damaging.
16. Don’t approach the machine when the machine runs.
3.2 Adjusting the Height
To get the most out of your flail mower, it should be set within the recommended height.
To save fuel and power
飞
and reduce wear and tear, the cutting height must be regulated
correctly.
When adjusting the working height, loosen screw (1), remove screw (2) on both sides; The
roller height (see following drawing) can be adjusted by aligning the selected hole in the
roller support bracket at position 2. The lowest hole is the highest working height; put the
screw (2) into the selected hole; tighten screw (1) and screw (2).
3.3 Flail Mower Adjustment
1. On a flat piece of ground
,
attach the Flail Mower to the Tractor using the 3-point linkage
2. Use a solid adjustable top link
3. Lower the 3-point linkage to its lowest position
4. With the roller at the rear in contact with the ground, adjust the length of the top link so
that the lower edge at the side of the flail mower is parallel with the ground
5. Rotate the blade drum by hand so that a row of blades hangs vertically towards the
ground.
6. Measure the clearance between the bottom of the extended blades and the ground.
 Minimum 50mm
 Note in rough or lumpy paddocks the clearance needs to be increased to ensure

8
that the blades don’t impact the ground in operation.
7. Adjust the roller height to increase or decrease the blade clearance as required
8. Go through steps 4 to 7 until the required clearance is achieved.
When the Flail Mower has been set up with the required tolerances: Operate the Flail
Mower with tractor in low range and the PTO delivering 540 RPM
3.4 Regulating the Tension of Driving Belt
ATTENTION: The machine shall always stand still for regulating
the tension.
Remove the driving belt cover.
1. Adjust the drive belt tension. The correct belt tension is achieved when the belt can be
deflected by the belt thickness about 10mm at the center point between the pulleys.
2. Align the gearbox so the drive shaft is parallel with the body.
3. Use a straight edge to make sure the belt pullies are in line and running true. If
misaligned, call your dealer or service agent for technical support.
3.5 Staring up
Before starting the machine, control and adjust the following items:
 Tension of trapezoidal driving belt.
 Oil level of gear.
 Point of lubrication
 All bolts, nuts and screws.
ATTENTION: When transferring the moving state of the machine to the
working state, do not stand between the machine and the
tractor.
The machine coupling is equipped with 3 pins so that the machine can be coupled with all

9
tractors with universal coupling with 3 pins. Each telescopic pole on the machine can be
adjusted properly according to the type of the tractor. Keep the Flail mower away the tractor
with a certain distance. The universal joint shall be tense and the largest distance in the
closed state shall be 5/10 cm.
Moving the lifting arm, and putting it between axes, insert the joint pins and fix them with
pins. Fix the lifting arm with chain and tensioning device so as to prevent lateral movement
of the machine. Connect the universal joint to the PTO shaft of the tractor on the side of the
tractor. In any event, it cannot produce a collision in any position. While connecting 3 points,
pay attention to that the PTO shaft of the tractor shall be parallel with the ground. It is very
important to keep the machine driving axle and the PTO shaft of the tractor in parallel.
The machine shall be lifted from the ground before moving the machine.
