Stopping The Machine In An Emergency
DANGER!
If the machine hits an object, becomes jammed, suddenly develops vibration or any other
potentially harmful change happens to the machine.
Stop the machine immediately!
If you hit a solid object or foreign debris:
Return the tractor to idle engine speed immediately.
Disengage the PTO.
Wait for the blades to stop rotating, then raise the reach arm and move the tractor off the object if safe
to do so.
Relieve hydraulic pressure in the system. This can be done by pulling/pushing the selected tractor
lever/button.
Press the emergency stop bottom on the reach arm controls to stop any potential movements whilst
inspecting the machine.
With extreme caution, if a blocked foreign component has caused the machine to suddenly operate
incorrectly or altogether ensure that all the correct levels of Personal Protection Equipment (PPE) is
worn for safety purposes. Consider gaining extra personnel for assistance.
If the cause of sudden incorrect running of the machine is due to the machine colliding or hitting a
foreign object, inspect the
area and remove, or mark the location of the debris so it’s not hit again.
Inspect the condition of the machine, reach arm and tractor and make any needed repairs before
proceeding to use the machine again. Make sure the blades are not damaged or broken and the
machine is intact and undamaged before resuming operation. If in doubt; do not restart.

General Cutting Hints
DO NOT
angle the attachment in such a way as to throw cut material towards the tractor.
Avoid rushing into the work.
Always give the blades enough material to 'bite' into, particularly when a hedge has a lot of leaf and
very flexible thin stems.
4.5.2
Hedge Cutting Hints
Consider how the job should be done before commencing work, as every hedge has a different height,
width, thickness and density of growth. Hedges that 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 to the
same shape and height as before.
Cutting causes the new growth to 'tiller' (spread out) 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. The following information gives a few hints on how to
tackle a hedge.
First trim the top down to the height of the previous year's trim in one cut, but do not cut into it as the
old growth will be very thick and strong and can cause premature wear to the blades.
Stalling the blades in heavy growth is likely to cause damage to the machine.
Next trim the sides to the previous trim but not into it.
