WARNING!
DO NOT pull the cutterbar in other way (towards the tractor), because it will lead
to cutterbar’s premature wear or even its damage.
NOTICE:
Too low a pressure in suspension disables the machine to be set in transport position.
If locking pawl does not catch when mower is being switched to transport position,
then increase pressure in suspension.
NOTICE:
Improperly relieved cutting unit of the mower will cause increase of cutter bar pressure
on the ground which will lead to faster wear of sliding skids, overload of cutter bar,
higher fuel consumption, damage to the stubble and contamination of the fodder.
5.7. Operation
5.7.1. Basic information on mowing
WARNING:
The operator must be seated in the tractor’s driver’s seat when the machine is
operating since only from that position is he able safely and properly operate the
mower. Before he leaves the driver’s seat, the operator must stop the engine,
apply the parking brake and turn off the tractor engine.
Always use appropriate protective equipment (safety footwear, gloves, ear protection and dust mask).
Before using the machine, make sure that all the safety devices are in their correct positions and in
a good condition. These safety devices must be immediately replaced if they are faulty or damaged. In
particular, the protective cover must be checked regularly. It must be immediately replaced if it is
missing or damaged in any way.
IMPORTANT: If a disc mower is your first experience (you have mowed with 2-drum mower), you need
a piece of essential information:
There is a difference - creased stubble, especially when it comes to lying grass. Straight grass may be
mowed with horizontal adjustment of the mower and then the stubble will be even, but it will not look
as attractive as with double-drum mowers. If the mower is inclined by approx. 2° to 3°, then the stubble
line is wavy. After the grass is mowed, it stands up, which makes an impression of inaccurate mowing.
5.7.2. Essential information concerning mowing
Optimum work parameters
❑ Keep the constant PTO rpm: 470 ÷ 540 rpm (for: SAMBA 160, 200, 240, 280) or 950 ÷ 1000 rpm
(for: SAMBA 320).
❑ Too high a PTO rpm whirls the air, which may cause inclination of the grass in front of discs, which
impairs the quality of mowing.
❑ Too low a PTO rpm impairs the quality of mowing and in some cases the mower stops mowing (too
low linear velocity of the knife).
❑ Driving speed – recommended of min. 8 km/h (5 mph). – the faster, the better result.
❑ In case of mowing soft meadows, the pressure of the cutter bar on the ground should be reduced
by adjusting support springs.
