Preparing mower for operation
Follow items 5.1, 5.2, 5.4, upon performing these activities the mower is ready for operation.
Then:
lower cutterbar freely until cutterbar touches the ground,
adjust the cutterbar setting with mower’s upper connector onto desired mowing height. Optimal
angle of cutterbar in relation to the ground should be between 0° and 5°. This angle is result of
tightening or extending the link,
open hydraulic valves (Fig. 8b),
with hydraulic cylinders (Fig. 12b) mount the mower on either tractor's left or right,
set the desired cutting width by folding guides back (Fig. 11) under proper angle,
slowly engage the mower's PTO shaft drive until cutting discs reach their nominal rotating
speed,
engage 2nd tractor gear and start mowing. If operating conditions allow engage the 3rd and if
don't engage back to the 1st.
NOTE:
Folding the mower back is forbidden, as it leads to faster wearing of the
cutterbar or even its damaging.

Operation
Dear User,
If operating disc mower is your first experience (previously operating with double drum
mower) then what you need is a piece of certain advice:
1. The biggest advantage of disc mowers is their lower power consumption by about 20%, lower
inertia moments and possibility of setting up mowers with larger mowing widths.
2. Some slight disadvantage might be considered less attractive, uneven stubble (upon harvest)
especially if laid grass needs to be mowed. Straight grass might however be mowed with
mower's horizontal setting and then the stubble is straight but not as nice looking as with double
or quadruple drum mower, as knives work horizontally to the ground and bowed grasses are
