Groundsmaster 4100--D Raise Cutting Deck Working Pressure Low Pressure (Charge) Return or Suction Flow Hydraulic System Page 4 - 12 Rev. E Groundsmaster 4100--D
Raise Cutting Deck A three section gear pump is coupled to the piston (traction) pump. The gear pump section farthest from the piston pump supplies hydraulic flow to the lift/lower control valve and the steering control valve. Hydraulic flow from this pump section is delivered to the two circuits through a proportional flow divider. The gear pump takes its suction from the hydraulic reservoir. When the cutting deck is in a stationary position, flow from the gear pump is by--passed through the lift/lower control valve, counterbalance manifold, oil filter, and traction charge circuit. To raise the cutting deck, the center lift lever on the lift/ lower control valve is pulled to allow valve shift in the lift/ lower control. This valve change allows hydraulic pressure to the rod end of the deck lift cylinders, causing the cylinders to retract. As the cylinders retract, the cutting deck raises. Oil from the piston end of the cylinders returns to the hydraulic reservoir. When the lift lever is released, the lift cylinders, and cutting deck, are held in position. To raise a wing deck, the appropriate lift lever (right side or left side) on the lift/lower control valve is pulled to allow valve shift in the lift/lower control. This valve change allows hydraulic pressure to the piston end of the lift cylinder and causes the shaft to retract, raising the wing deck. Oil from the rod end of the cylinder flows to the traction charge circuit. When the lift lever is released, the lift cylinder, and wing deck, is held in position. An adjustable counterbalance valve maintains back pressure on the lift cylinders. A relief valve located in the lift/lower control valve limits circuit pressure. Excess circuit flow is routed to the oil filter and then to the traction charge circuit. Hydraulic System Groundsmaster 4100--D Page 4 - 13 Rev. E Hydraulic System
