Adjusting The Height Of Cut
The cut height can be adjusted by raising or lowering the flail head roller to suit the material to be cut and the
required degree of chopping, see Figure 6. Support the skids at both ends by blocks. The size of the blocks
should be sufficient to give enough free movement of the roller bracket (B) to achieve the desired cut height.
Ensure that the machine will not slide off the blocks. Support the roller appropriately - it is heavy! Undo
setscrew (A) on the roller bracket at both ends of the machine. Raise or lower the roller to the desired height by
aligning one of the roller bracket setscrew holes with the hole in the cowl side plate. Make sure that the same
hole is selected at both ends. Failure to do this will produce an uneven cut. With the roller still supported, re-fit
and re-tighten the setscrews on both roller brackets. Remove the roller support and the blocks to lower the
machine to its new cut height.
CAUTION
! Do not allow the rotor flails to contact the ground - set roller height to allow a minimum flail to
ground clearance of 1cm.
CAUTION!
The machine must always run on the rear roller not the side skids
– side skids are a
protection feature and in normal working conditions remain clear of the ground.
