4.4 DURING WORK
Proceed in the following way after you have correctly hitched
the machine, sat down in the driver's seat of the tractor and

cut
Run the engine at a low rate and engage the PTO
Gradually accelerate until the PTO is operating at full rate
- Engage the forward gear and start work with the PTO at
full rate
Gradually lower the machine until it rests on the ground.
This allows it to adapt to the contours of the soil.
Drive a short distance and check to make sure that the
plants and undergrowth are being cut to the required
degree.
The cutting height is regulated by adjusting the rear roller
as indicated in point «
PCertain factors must be taken into account when choosing the
most suitable cut, i.e.:
the height of the stalks
the quantity and size of any twigs and branches on the
ground
the ground speed of the tractor
optimal cutting height adjustment
the nature of the soil
A good cut is obtained at a low ground speed and with the blade
rotor turning at high speed.
