WARNING!
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. Preparing the mower for operation
Before operation please learn the above provisions in 5.1. Attaching the mower to self-
propelled mower FORTSCHRITT. After the above is completed the mower shall be considered
as ready for operation. Then depending on a machine version, follow instructions given hereinafter.
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.
 Too low PTO rpm impair the quality of mowing and in some cases the mower stops
mowing.(too low linear velocity of the knife).
 In case of mowing low grass, front safety guard should be lifted to reduce blasts of wind around
the discs and reduce the pressure of the safety guard on the grass.
 In case of mowing soft meadows the pressure of the cutterbar on the ground should be reduced
by adjusting support springs.
5.3. Operation
5.3.1. Basic information on mowing
 Cutting height is adjusted by the regulating bars (Fig. 2), 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.
 In real life the user should use so called "common sense". In regards with this during intense
usage the cost of necessary service checks should be taken into account - see point 11.
