Hydraulics control assembly
Control assembly I
)
:
Single-section distributor (
12
) is responsible for starting the cutterbar. The drive is started from
the tractor's cabin using the control system. Sweep valve of distributor is set on 180 bar. On tank fill
there is oil cooler (
14
). Cooler radiator is started when oil temperature exceeds 65
o
C.
Control assembly II
)
:
Four-section (
13
) or five-section distributor is responsible for tilt of the machine's arms, extension
rotation to proper mowing/transport position as well as settings of the cutterbar (control is specified
in chapter 5.5.1. Control panel operation). Sweep valve of distributor is set on 180 bar.
6.5.6.
Initial regulations
Four hydraulic cylinders (
1)
, (
2
) are equipped with throttle valves (
15
) (
),
designed for regulation of oil flow. Their task is to adjust settings for any machine's operator. Reducing
oil flow improves operation of cylinders (eliminates jerks), but at the same time slows down their
operation. Setting is performed by turning the valve rotary handle:
Turning right
–
reduces capacity, improves operation, slows down the cylinder's operation.
Turning left
–
improves capacity, causes jerks, accelerates the cylinder's operation.
