Adjusting ground speed
Adjust work speed based on the amount of material to be shredded as well as how finely it is to be chopped up. As a
general rule, drive the tractor no faster than 8 km/h.
6.2
Adjusting cutting height
To adjust the cutting height of the tools, you need to adjust the position of the skids and rear rollers or wheels (optional
extra).
WARNING!
You need to position the tractor on a stretch of flat ground, with the engine switched off, the
parking brake on, the PTO disengaged and the key removed from the ignition and kept in a safe place.
Adjust the height of the rear rollers and side skids so that the PTO is parallel to the ground when the machine is
positioned parallel to the ground. Flails must work at least 20 or 30 mm off the ground. The side skids actually have to
be at least 20 mm lower than the skids working range. As a general rule, the skids must always be set to a height
where they will not come into contact with the ground.
