Geared pumps power two independent circuits: machine's drive circuit with capacity of 50 l/min
and hydraulic cylinders' drive circuit with capacity of 11 l/min (22 l/min. - EP). In machine's drive
circuits wires have
∅
16 mm diameter, while in cylinders' control circuit
∅
10 mm. Control of oil
circulation is possible owing to hydraulic distributors (3, 6). Oil tank (4) of adequate capacity. In
arm-type mower's hydraulic engine's drive circuit there is suction oil filter (5) with capacity of 70
l/min. On gauge plate cylinder (8) there is sweep valve (7) mounted to protect the mower's arms from
overloading (Fig. 22) Hydraulic cylinders (9-12) with throttle choke valves (13) control the arm.
