SECTION 4

4.5.5 MOWING

DANGER
The mower may only be started when all guards are in place and the cutting unit is set in
working position.
Before engaging drive to PTO shaft make sure that there are no bystanders, especially
children, near the mower.
Other persons should be at a safe distance from the mower during work because of the
danger that objects may be thrown (stones, branches from beneath rotating disks).
After setting mower in working position, setting cutter bar, observe the following procedure:
Lower the cutter bar lifting arm until the cutter bar rests on the ground. Engage the PTO in
the tractor at a suitably low speed and then gradually increase the speed until PTO speed of
540 rpm is reached. During starting the cutting unit generates considerable noise. Noise is
reduced when mower is driven into standing crop. During cutting the lever controlling the
hydraulic circuit, lifting the cutting unit, should be set in "floating" position.
HIGH NOISE LEVEL WARNING
Depending on the working conditions, the tractor with the machine may generate noise
exceeding the level of 85dB at the driver position. In such conditions the driver should
apply individual protection (protective ear guards).
In order to reduce the level of noise during work the tractor cab window and door
should be closed.
When mowing pay special attention to uneven surface and any large objects lying in the
grass. Mowing speed depends on the quantity and quality of mown crop but also on the type
of terrain.
Mowing speed must be reduced if:
• mown ground is uneven,
• crop is laid, or very tall and dense,
• there is a great risk of running into foreign bodies e.g. stones, branches and heaps of
soil.
Be especially careful when mowing along ditches, furrows and slopes. When making turns,
raise the cutting unit by means of the arm lifting cylinder, without the need to change the
height of hoist lower links in the tractor. When mowing on hilly terrain or on slopes make
turns so that the cutting unit is set up the slope.
