3.2.5 SUPPORT HYDRAULIC SYSTEM

The support hydraulic system – figure (3.11) – allows to automatically extend and fold the
support (3). This is achieved by extending or retracting the hydraulic cylinder's rod (4). The oil
is supplied to the support hydraulic system from the tractor's system by means of a line (1).
The hydraulic cylinder of the support is controlled by means of the tractor's external hydraulic
system distributor.
