Cutting Head Set-Up - MP head
Direct Drive option minimises weight at the end of a long arm by compact mounting
and benefit of reduced maintenance. Running at a single speed of 2800 rpm.
Belt Drive optimises cutting performance with a choice of rotor speeds.

Fast 3100 rpm to provide extra cutting tip speed for fine finish on annual
hedge trimming (rotor pulley 150 Ø. Motor pulley 160 Ø).

Standard medium speed setting of 2700 rpm for general work in grass and
hedges (rotor pulley 160 Ø. Motor pulley 150 Ø).

Slow 2500 rpm to provide extra torque with more power for grass mowing and
overgrown hedges (rotor pulley 160 Ø. Motor pulley 140 Ø).
Cutting Width
Standard 1.2m is suitable for both grass and hedges, and optimises power to weight
ratio.
Optional 1.5m is best used for hedge trimming to reduce the number of passes.
However, there is less power per flail, and an increased weight penalty, which is not
recommended on long reach machines and especially not for grass cutting.
Warning
Never operate the machine with the 140 Ø pulley on the rotor and the
160 Ø pulleys on the motor. This will over-speed the rotor and is very
Dangerous.
Warning
Never attempt to operate the machine without the rear roller correctly
fitted. The roller performs a key safety function should the rotor shaft
pick up wire. It is essential for operator safety that it remains in place.
It is also an essential structural part of the cutting head. Removing it
will cause premature wear on rotor bearings and will lead to
premature wear on the fabrications.
