5.7. Preparing mower for operation – mower with hydro-pneumatic support
NOTICE:
Before sale SaMASZ protects the cylinders with special grease against
weather which may cause premature wear. Before operating the mower,
remove the excess grease from the cylinders.
IMPORTANT: If the pressure supporting the assembly of the cutterbars is too high, the
cutterbars will not be able to lowered.
IMPORTANT: Too low a pressure in suspension disables the machine to be set in
transport position. If locking pawl is not caught when mower is being
switched to transport position, then increase pressure in suspension.
NOTICE:
Improperly relieved cutting unit of the mower will cause increase of
cutterbar pressure on the ground which will lead to faster wear of sliding
skids, overload of cutterbar, higher fuel consumption, damage to the stubble
and contamination of the fodder.

5.7.1. Mower version with controller

Engaging mower's drive should be performed once cutterbar is placed on the ground.
The following should be performed in workplace and as mower is in operating position:
hang the machine on the 3-point linkage. Connect hydraulic hoses, control panel power cord

and signal cable RS 232,
lower cutterbar so it touches the ground,

connect PTO shaft extension of the tractor rpm (unless only one extension was taken out or

connect the complete PTO shaft),
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. The same principle applies to mowers equipped with
conditioner or rollers,
slowly engage the mower drive until cutting disks reach their nominal PTO rotating speed of

950 ÷ 1000 rpm. Rears should be considerably lower, so that tractor's fuel consumption can be
reduced.
engage proper tractor gear and start mowing. Even meadows can be mowed at any driving

speed, however as unevenness occurs the speed should be reduced.
Engaging mower's drive should be performed as cutterbar is on the ground, so that oil fills
the cutterbar. In workplace and as mower is in operating position, it should be set pressure in
unloading system.
