Essential information concerning mowing

Optimum work parameters
1. Inclination towards the front 0-5 degrees which equates to 1.8" - 2.8" of mowing height.
2. Operation speed around 6 mph or more, if the conditions allow.
3. PTO rpm = 950-1000 rpm. PTO rpm less than 1000 may cause stripes of uncut grass between
the disc. On Client's special request: PTO rears = 470 ÷ 520 rpm. PTO rears > 540 rpm may lead
to leaving pieces of uncut grass between discs.
High and inclined grass
4. Heighten the cutterbar's inclination to H = about 1.8".
5. If there is no inclination the grass will be wedged on the forming drums.
6. Speed can be more than 8 mph (the faster – the better)
7. Do not turn in the mowed grass.
Optimum inclination of the cutterbar towards the ground is between 0° to 5°. If the inclination
exceeds 5°, there might be a slight unevenness of mowed grass. It impairs slightly the quality of
mowing and has an influence on the mower's operation. Inclination of the cutterbar to the other
side quality of mowing is significantly impaired and in extreme situations, it may lead to
damaging the cutting unit. When higher mowing heights are required, use optional toppings for
high mowing.
When high grass prevails, first and second cut should be mowed at height level 2.4" - 2.8", but
when the grass grows low it should be mowed at 2". The last cut should be mowed a little bit
higher, 2.8" - 3" above the ground.
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).
