Hedge Trimming
Consider how the job should be tackled before commencing work, as no two hedges have the same height,
width, thickness or density of growth. Hedges which have previously been cut by machine tend to have
denser growth, and although they can be cut to any desired shape, it is advisable to trim the same shape and
height as previous years.
The flails cause the growth to "tiller' and thicken up the hedge. Therefore it is advisable to cut the hedge side
at a slight angle rather than straight, otherwise the hedge may eventually die at the bottom due to lack of
light.
Below are a few hints on how to tackle a hedge.
A. First trim the top down to previous years's trim in one cut, but do not cut into it, as the old growth will be
very thick and strong and cause premature wear to the flail cutting edges.
B. Next trim the sides to the previous trim but not into it.
NOTE: Do not angle the rotor unit so that any debris is thrown through the hedge when trimming the far side
of the hedge. Always ensure cut material is directed away from you or on to the ground.
C. Finally, lower the roller and trim along the bottom of the hedge to clear debris and undergrowth.
Stalling the Rotor
If the rotor does become choked the tractor will stall or the relief valve will operate. If this occurs follow the
instructions below.
A. Stop forward movement and disengage rotor drive immediately and place PTO drive lever in neutral.
B. Ensure that the rotor has stopped and lift the rotor unit using the hydraulics.
C. Stop tractor engine engage parking brake and wait for all rotation to come to a complete stop.
D. Remove any obstruction that may be present on the rotor. If working under the raised machine ensure
that it is safely supported.
E. NEVER UNDER ANY CIRCUMSTANCES run the rotor to "clear itself".
