improved, through a CAN (Controller Area Network)

communication link, enabling a continuous exchange of

information between the engine and the hydraulic

system. These units are now perfectly synchronised.

Large capacity of pump, harmonized with engine provide sufficient hydraulic flow for fast working speed with a large attachment.
