Hydraulic Connection
The feed and return hoses from the machine must be connected to the respective
external service connections of the tractor hydraulic system. Both feed and return
hoses have labels with arrows indicating the direction of oil flow.
The tractor hydraulic system must be set to constant pumping. Consult the tractor
manufacturers handbook for details about connecting external equipment to the
hydraulic system and hydraulic pump settings.
Required oil flow from tractor system
minimum 70 ltr/min
(Set to constant pump) maximum 100 ltr/min
(For flows greater than 100 ltr/min consult your officially appointed Standen dealer)
There must no restriction in this return oil. Ensure that there is a full flow return, or
even better return straight back into the tractor gearbox. Consult your tractor
handbook or dealer for further information.
Open/Closed Centre Hydraulics
Two types of hydraulic system are currently in use by tractor manufacturers, namely
OPEN CENTRE or CLOSED CENTRE configurations. Consult the tractor
manufacturers handbook or dealer for further information.
The main hydraulic valve bank, situated behind the rear LH guard of the machine,
incorporates an adjustable screw (item 1, fig 4) which enables easy changing from
closed to open centre and vice versa. For closed centre configuration tractors, turn
the screw clockwise until fully closed. For open centre, turn the screw anticlockwise
until fully out.
