Working Height Adjustment; Flail Mower Adjustment - Hanmey Implements AGL Series Operation, Service & Parts Manual

WORKING HEIGHT ADJUSTMENT

The machine's working height is determined by the position of the rear roller. Lifting
the roller the cutters get close to the soil, whereas lowering it the cutters get far from
it. After a modification of the working height be sure that the cutters skim the ground;
a direct contact with it would cause their wear and this could affect the cutting rotor
balance and may cause objects to be thrown out from under the mower deck.

FLAIL MOWER ADJUSTMENT

- On a flat piece of ground, attach the Flail Mower to the Tractor using the three point
linkage
- Use a solid adjustable top link
- Lower the three point linkage to its lowest position
- 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
- Rotate the blade drum by hand so that a row of blades hang vertically towards the
ground.
- 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
that the blades dont impact the ground in operation.
- Adjust the roller height to increase or decrease the blade clearance as required
- 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 1000 RPM
