(7000 Series) Pull and lock the hydraulic function control lever rearward.

5. (8000 Series) Pull SCV No. 1 switch rearward to detent position (until click is felt) and release. The machine should be lifted by the 3-point hitch and the lift-assist wheel. The lift-assist wheel should be on the ground when the machine is fully raised. If this action does not result, check orifice and see your John Deere dealer for hose diagrams.

6. Moving the hydraulic function control lever forward should lower the machine and raise the lift-assist wheel off the ground.
