Switching from transport to working position.
open the shut-off valve on the hydraulic cylinder (Fig. 11a),
lower the mower until the cutterbar is at least 50 cm above the ground (Fig. 12),
make sure there is nobody around in the place where you are going to lower the mower,
tighten the cord until the lock Z is released (Fig. 10b.) and by means of hydraulic cylinder put the
mower into horizontal position,
with tractor’s lever lower the cutterbar to reach the horizontal position in a possibly slow way,
lower the mower until the support chain tightens. If the 3-point linkage frame is more than 40 cm
above the ground, adjust the chain.
unblock the ground following bracket. See warning decal 23 page 15
by means of link S (Fig. 9) adjust the cutting height. Extending the link S increases the cutting
height and shortening the link reduces it.
The proper distance between the end of cutterbar and tractor’s tyre Y should be about 0 to 10 cm
for KDT 180, KDT 220, KDT 260.
For KDT 300 Y should be from 30 to 40 cm.
For KDT 340 from 50 to 60 cm.

Preparing the mower for work.
Put the mower into motion when the cutterbar is on the ground so that oil can fill the whole cutterbar.
When the mower is in working position, please do the following:
lower the cutterbar to the ground,
connect PTO shaft between tractor and mower,
by means of upper regulating bar of the mower, adjust the cutterbar’s height and inclination
towards the ground. Proper inclination of the cutterbar is between 4° and 5°. It is regulated by
extending or shortening the bar,
slowly engage PTO clutch and wait until the cutting unit reaches its rated speed. DO NOT exceed
950 ÷ 1000 rpm.
engage tractor gear and drive slowly into the grass-field. Flat meadows can be mowed with any
speed. If the meadow is uneven reduce speed.
