Tracks
The chassis of the machine is provided with two
hydraulically powered tracks.
The tracks are suspended at the front of the chassis and
connected through a triangle with its turning point
about the centre of the chassis at the rear end of the
machine.
The tracks can move independently of one another, and
thereby 100% ground contact of the machine is always
ensured, even when driving on uneven ground.
When driving in hilly terrain where the soil is loose,
rubber spikes can be obtained for the tracks as optional
equipment. Thereby the grip of the tracks on slopes will
be increased. Look at chapter 11.2

Motor and hydraulics
The machine is equipped with a 13 hp air-cooled Briggs and Stratton, which powers the
hydraulic pump and the flail mower through a belt drive. In the driving line between mower and
motor there is an electromagnetic coupling with springs that automatically disconnect the
mower, if the current disappears. The coupling is engaged and disengaged with the remote
control.
At the rear end of the machine a suction box is mounted, through which the motor sucks its
cooling air.
The hydraulic pump is provided with a fan blade that directs cold air around the pump housing
to prevent excessive heating of the hydraulics. A hydraulic oil cooler is also mounted in the
suction box.
The speed and direction of the machine is regulated by the quantity of oil that each of the
hydraulic motors for the tracks gets from the pump. The oil quantity given by the pump to each
of the two hydraulic motors is decided by two servomotors, which are connected to the speed
control alarm of the pump. These servomotors are controlled with the remote control.
