Operation; Adjusting The Mower To Work Conditions - SaMASZ KDF 390 Operator's Manual

CAUTION:
Use the machines with PTO shafts designed to drive them. Before the work
begins, check the safety guards (in tractor, mower and PTO shaft), if they are
placed correctly and are not damaged. Damaged or lost parts must be
replaced with genuine ones. Make sure the PTO shaft is properly mounted. It
is forbidden to approach the rotating parts, because it may lead to serious
injuries or even death. All service and repair operations must be done only
after the tractor engine has been stopped, all rotating parts have come to the
complete standstill and the cutterbar is on the ground. Before the operation
begins, read operator's manuals of both the machine and PTO shaft.

5.2. Operation

Cutting height is adjusted by the regulating bars (Fig. 2, pos. 9), which connect suspension
frame to the main frame. It enables proper cutterbar inclination and cutting height adjusment.
Drive should be turned on, when the cutterbar comes to conntact with the ground.
Slowly engage the PTO clutch and wait until the cutting unit reaches its rated speed. engage
tractor gear and drive slowly into the grass-field.
Swath guides with adjustable swath width mounted in the mower allow the machine
FORTSCHRITT to drive on not causing crush to grass by the wheels.
1.2 m – 1.6 m wide swath may be collected with self-collecting trailer or baler.
5.2.1.

Adjusting the mower to work conditions

Optimum inclination of the cutterbar towards the ground is between 0° to 5°. If the inclination
exceeds 5°, there might be a slight unevenness of the mowed grass. It impairs slightly the
quality of mowing and has an influence on mower's operation. When the cutterbar is pulled in
the other way, it significantly impairs the quality of mowing and in some cases the mower stops
mowing. Besides, it may lead to premature wear or even damage of the slides and cutterbar.
Too high PTO rpm whirl the air, which may cause the inclination of the grass in front of the
discs. It impairs the quality of mowing.
