Raising the Cutting Deck
g292091
Hydraulic System: Hydraulic Flow Diagrams
When the cutting deck lift lever is moved to the RAISE position, hydraulic fluid
flow is directed to the deck lift cylinders. The hydraulic pressure against the
cylinder pistons retracts the lift cylinders, lifting the cutting deck. When the deck
lift cylinders reach the end of their stroke (or if the lift arms are prevented from
raising any further), the relief valve in the steering control valve opens and directs
the hydraulic flow back to the pump until the lift lever is returned to the neutral
position. The pressure relief valve opens at 120-125 bar (1,740-1,813 psi).
Note: If the cutting deck lift lever is moved to the RAISE position while the
steering wheel is being turned, the cutting deck lift speed will be reduced.
