B296 Mower unit pressure sensor detects the pressure when raising and lowering the mower units. This signal deactivates individual mower unit lifting in automatic mode. When the pressure sensor detects no pressure change for more than 2 hours, the electric system is shut down.

Y407 Left mower unit load relief solenoid coil Solenoid valve energised: Hydraulic oil flows into the piston top space of the left mower unit load relief hydraulic cylinder (3195) = Increase of mower unit load relief. Solenoid valve not energised: Closed position of left mower unit load relief hydraulic cylinder (3195).

Y408 Right mower unit load relief solenoid coil

Solenoid valve energised: Hydraulic oil flows into the piston top space of the right mower unit load relief hydraulic cylinder (3196) = Increase of mower unit load relief. Solenoid valve not energised: Closed position of right mower unit load relief hydraulic cylinder (3196). Y412 Left mower unit solenoid coil is energised for raising and lowering the left mower unit hydraulic cylinder (3132); at the same time, the left mower unit LS priority solenoid valve (Y410) is energised. Solenoid valve not energised: Closed position of left mower unit hydraulic cylinder (3132). Y413 Right mower unit solenoid coil is energised for raising and lowering the right mower unit hydraulic cylinder (3133); at the same time, the right mower unit LS priority solenoid valve (Y411) is energised. Solenoid valve not energised: Closed position of right mower unit hydraulic cylinder (3133).

Y414 Left mower unit height block valve solenoid coil Solenoid valve energised: Hydraulic oil flows into the piston top space of the left mower unit hydraulic cylinder (3132); at the same time, the left mower unit LS priority solenoid valves (Y410) and the left mower unit solenoid valve (Y412) are energised. Solenoid valve not energised: Closed position of left mower unit hydraulic cylinder (3132).

Y415 Right mower unit height block valve solenoid coil Solenoid valve energised: Hydraulic oil flows into the piston top space of the right mower unit hydraulic cylinder (3133); at the same time, the right mower unit LS priority solenoid valves (Y411) and the right mower unit solenoid valve (Y413) are energised. Solenoid valve not energised: Closed position of right mower unit hydraulic cylinder (3133).
