5.7.3 The way of stand cutting
Set the engine on the maximum speed, let the cutting blade rotate at the maximum
speed and then get the machine into motion, facing the to-be-cut stand.
At cutting, you should proceed only in such a way that the to-be-cut stand is - if
possible - on the left side of the machine. When cutting on slopes, it is advised to drive the
machine along the slope contours. Watch a maximum permissible long-term machine
inclination of 20° (30° over a short-term – up to 30 sec)!
If the cut stand is very dense, grown through, rotten from below or lodged, the
machine cutting width must be accordingly reduced, greater cutting height adjusted or
machine travel speed reduced so that the cutting blade rotations are not excessively slowed-
down, which would result in the impaired cutting quality and engine overloading.
5.7.4 Problems at cutting
Choking of the space under the cutting blade cover with the grass biomass shows in:
a) Engine markedly losing speed but not stalling: wheel drive to be switched off
immediately (lever on the left handrail grip); the machine front to be slightly lifted by
pushing down on handrails. Then shift in reverse gear (R) and slightly back with the
machine. The space under the cutting blade cover will do itself a partial clearance
from excessive grass. Then drive the machine against the stand again.
b) Engine losing rotations and stalling: release both levers on the handlebars, start the
engine, shift in reverse gear and back with the machine out from the stand to be cut.
Switch off the engine. Clean the space under the cutting blade cover and spread the cut
grass across the ground surface. Start the engine, switch on the cutting blade drive and
drive the machine against the stand again.
Be very careful while lifting the machine and driving on reverse gear!
