slowly turn on the power to the mower bringing the cutting discs to the nominal rotational speed of
❑
the PTO of 950 - 1000 rpm. The rpm's should be as low as possible to decrease tractor fuel
consumption,
engage tractor gear and drive slowly into the grass-field. Flat meadows can be mowed at any driving
❑
speed, while in uneven terrain the speed should be adjusted to working conditions to minimize the
likeliness of risk.
NOTICE:
Too great pressure in support unit of cutterbars disables lowering of cutterbars from
transport to working position.
NOTICE:
Increasing pressure – lower impact on the ground.
Reducing pressure – bigger impact on the ground.
WARNING!
Improper unloading of the mower's cutterbar will result in increased pressure of
the bar onto the ground which may result in: faster wearing of sliding skids,
overloading the cutterbar, increasing fuel consumption, damaging the turf and
causing contamination to forage.
NOTICE:
After switching button (3)
position will follow after 1 minute - even without the need of the operator's action.
WARNING!
Making the oil flow from the tractor to working system will cause increase of
pressure in the system.
WARNING!
Tilting the mower back is forbidden as it will cause faster wear or even damage
of the cutterbar.
