Table 4.2
– Input Shaft/PTO Speed Options
Multicut 300 machines feature an automatic torque limiter on the input shaft.
NOTE:
Some tractors offer the ability to change the PTO operating speed between 540/1000 RPM. Ensure that
the correct PTO operating speed is selected for the machine
. Refer to the tractor owner’s manual for
instructions on how to change PTO operating speed before proceeding to start the machine.

Setting Up The Machine
It is important to set the machine up properly front to back to ensure for safe operation and efficient working
ability. A properly set up machine will give a more uniform cut, follow ground contours better and distribute its cut
material more evenly out of the rear of the machine. It will also require reduced tractor work and effort from the
operator.
Setting up the machine should always be carried out with the machine on the floor resting on the rear wheel.

Equipment Required

Tape measure
WARNING!
It is mandatory to switch the combustion engine off and disengage PTO and ensure that
the machine is stopped and the parking brake is engaged b
efore leaving the driver’s seat and
proceeding to adjust the levelling of the machine.
Once coupled to the tractor, check the machine is cutting level from the front to the rear.
To level the machine front to rear:
Place the machine on a level concrete surface, with the machine lowered onto the ground. Depending
on the position of the rear wheels/setup, this will be either on the rear tyres or directly or the machine
skids.
Measure the machine at the front and rear of the skids; see Figure 4.9 to determine the height of the
front and rear of the machine.
Adjust the top link between the tractor and machine headstock in order to raise or lower the front of the
machine if required. Lengthening the top link will raise the front of the machine and shortening the top
link will lower it.
Aim to adjust the machine so that the front of the skid is pitched around 1
5mm (1”) higher than the
rear. This has been found to give the most efficient operating ability and best cut from the machine.
Secure the top link in position so it will not change positions during work or transport.
IMPORTANT:
Ensure that the machine tyre pressures are set correctly (if fitted). See Section 5.5.1 for correct
tyre pressures.
NOTE:
Keep in mind that the tyres may sink in soft conditions when the machine is in use altering the actual cut
height; see Figure 4.10. As a safe precaution, set the cutting height slightly higher on set-up to cater for this
sinking. Assess the working area after and then adjust again if required.
