Main control valve (5) Bucket control valveThe oil delivery from drive pump (17) flows through parallel feeder passage (12) in main control valve (13) to bucket control valve (5). The bucket control valve does not utilize the output flow from idler pump (16) .When the joystick for the bucket is moved to the BUCKET Close position, the pilot oil flows from pilot pump (18) through pilot control valve (15) to pilot line (2). The pilot oil flows through pilot line (2) to bucket control valve (5) and the pilot oil shifts the spool of bucket control valve (5) downward. When the bucket control valve is shifted downward, the oil flow from drive pump (17) in parallel feeder passage (12) flows through passage (10) to check valve (8). The oil flows through check valve (8), through passage (6), and to bucket control valve (5). The oil flows through bucket control valve (5), through passage (7), and through line (3) to the head end of bucket cylinder (1). The oil extends the cylinder rod of bucket cylinder (1). This allows the bucket to close.Return oil from the rod end of cylinder (1) flows through line (4) and passage (9) to bucket control valve (5). The oil flows from the bucket
