Hydraulic oil is pumped from the pilot pump (8) to control valve group (6). From control valve group (6) oil travels to valve control group (4) and into spool (5). Spool (5) is shifted up allowing oil to flow through and into hydraulic line (2) leading to grapple (1). Oil flows through grapple (1) causing the grapple to rotate. The oil then returns to tank (9).

Hydraulic oil is pumped from the pilot pump (8) to control valve group (6). From control valve group (6) oil travels to valve control group (4) and into spool (5). Spool (5) is shifted down allowing oil to flow through and into hydraulic line (3) leading to grapple (1). Oil flows through grapple (1) causing the grapple to rotate. The oil then returns to tank (9).
