Position 2 – Stubble height ca. 5 cm
Position 3 – Stubble height ca. 3 cm
5.6.2 Mowing of grass stands

Prior to the machine use, the stand must be cleared of solid bodies such as stones,
wires, loose construction debris, etc., which could be flung or might otherwise
damage the machine. Should these be impossible to remove, pass the places by.

Mowing engagement width has to be at all times accommodated to stand density!

In dense or high grass stands it is always necessary that the guide wheels or slide
shoe are adjusted at the highest position!
Adjust the engine on maximum speed, let the mowing knife rotate at maximum speed
(see chapter 5.3) and get the machine into motion (see chapter 5.4) against the stand to be
cut. If the stand is too dense, grown through, rotten or lodged, the machine engagement
width must be reduced accordingly so that the rotations of the mowing knife are not being
excessively reduced and the cutting quality impaired.
If the space of the casing of mowing knives gets choked, there are three possibilities for
a solution:
a)
Engine loosing speed
: cutting height to be adjusted higher (see chapter 5.6.1) and
engagement width to be reduced;
b)
Engine markedly loosing speed but not stalling
: machine travel to be switched off
immediately (lever on the left handrail); drive in reverse gear just a bit with a
simultaneous slight elevation of the machine front (by pushing down on the handlebar
