6.2 Electro-hydraulics (special feature)
The hydraulic system can be driven as an open system with max. 80 l. /min. The tractor requires a double- and a
single-acting control valve with free return (red=supply;blue( thick hose)=return for the hydraulic connection.
A free return directly to the hydraulic oil tank is preferable as it involves less tailback pressure. The flow regulator
for the neutral circuit and the speed adjuster for the small consumers such as pick-up, the articulated drawbar,
tailgate etc. are to be found in the pump inlet plate. The speed adjustment for consumers other than floor conveyor
and cross conveyor is regulated from the adjusting screw (1). The flow rate can be set from 1 – 16 l. / minute.
If the tractor control valve is actuated, oil flows through the
hydraulic system.
(Attention: Always ensure correct flow direction!)
The tractor control valve lever should always be locked in
place so that it does not have to be held onto constantly.
The functions required can now be selected directly from
the control box using the toggle switches.
Attention: Before depressurising the hydraulic system again
via the tractor control valve, the toggle switches on the
electrical control box must be put to zero position.
High accident risk!

6.3 LS – Connection
The self-loading trailer hydraulic system can be regulated with the tractor LS system. (The hydraulic pump’s pres-
sure and delivery rates are adjusted to current need).
For this purpose the LS connection on the tractor is connected up to the LS connection (2) fig. 3.1 on the self-loa-
ding trailer control valve.
The supply is connected directly to the hydraulic pump.(Not via the tractor control valve).
Attention:
Never use the pressure connection without the LS connection.
The pressure regulator must be blocked by screwing in the bolt (3) fig. 3.1 as far as it will go. The regulating
current cut-off must be set to open system.
Attention: If connecting via the tractor control valve, the bolt (3) will have to be screwed out again as far as it will
go.
