In the case of a mower equipped with the control panel in
Fig. 16
, perform the following
actions:
start control panel,
lift mower on tractor's 3-point linkage up in order to eject cylinder rod to maximum out the
cylinder,
then press button (
15
)
on control panel to set pressure in hydro-pneumatic assembly,
using tractor's hydraulic valve lever set the pressure until mower's cutterbar is slightly chattered,
turn off button (
15
)
on control panel,
set mower in working position.
In the case of a mower equipped with a simplified control panel (
Fig. 18
), proceed in
accordance with point
5.3.1
.
5.7.2.
Mower version with controller
The following should be performed in workplace and as mower is in operating position:
hang the machine on the 3-point linkage,
lower cutterbar so it touches the ground using three hydraulic outlets of the tractor
(see p. 5.1.1.3),
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.
lift mower on tractor's 3-point linkage up in order to eject cylinder rod to maximum out the
cylinder and the cutterbar should touch the ground,
using tractor's hydraulic valve lever (connected with red hose
A
(
Fig. 14c
), set the pressure
until mower's cutterbar is slightly chattered,
lift the mower on the three-point linkage of the tractor up about 30 cm above the ground.

Preparing the mower for work – mower with support springs
Put the mower into operation 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:
be sure cutterbar is on the ground,
connect PTO shaft between tractor and mower by means of the tractor's external hydraulics,
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 0° and 5°. It is regulated by
extending or shortening the bar,
you can operate either with or without belt conveyors. If an operator is willing to work without
belt conveyors, they must be lifted by means of the tractor’s hydraulic system. Before lifting,
the cotter pin must be unblocked,
slowly engage PTO clutch and wait until the cutting unit reaches its rated speed. DO NOT
exceed 950 - 1000 rpm. Tractor's engine rpm should be considerably lower, so that the fuel
consumption could be reduced,
