Flail Cutting Unit General
Information
It is important to keep the flail blades sharp and in good
condition to ensure good cutting performance, minimum
power consumption, and a good quality of cut.
The flail head is a fine cut flail and should only be used for
maintaining grass. Its recommended that a maximum of 1/3
of the total grass length is removed when cut.
The scraper wires are fitted to remove debris from the
roller, in dry conditions these may not be required and its
recommended they are removed. In damp wet conditions
ensure that scraper wires do not get plugged with debris.
The cutting unit floats and can pivot laterally to follow ground
contours.
The cutting units are designed to be operated at full engine
rpm. Forward speed should be adjusted depending on grass
conditions and to not overload the power units or the heads.
The lower the forward speed the higher the quality of cut
and after cut appearance.
Adjusting the Height of Cut
Note:
The height of cut is gauged by the rear roller. Blade
wear, worn cutting unit pivots, bent/damaged cutting unit
pins, and bent/damaged arms can affect the height-of-cut
setting.
1.
Turn the adjusting-nut assembly on both ends clockwise
to decrease the height of cut or counter-clockwise to
increase the height of cut (
