BACKHOE
1. HYDRAULIC SYSTEM
[1] HYDRAULIC CIRCUIT
To operate the backhoe, the hydraulic oil pressurized oil by the hydraulic pump flows pump from pump port P
through six control valve (the bucket control valve, the dipperstick control valve, the stabilizer RH control valve, the
stabilizer LH control valve, the boom control valve and the swing control valve) to P.B. port (to front loader control
valve).
Since the relief valve is not equipped in the backhoe control valve, the main relief valve in the tractor operates.
