Functions of the Valves on the Block

The main hydraulic valve block controls 6, 7 or 8 functions of the combine through individual modules (valves) depending upon the configuration and combine model:

- 1450/1550 (without lateral tilt and without reel forward and backward system) = 6 functions

- 1450 CWS (without lateral tilt) = 7 functions

- 1450 with lateral tilt = 8 functions

- 1550 CWS (without lateral tilt) = 7 functions

- 1550 with lateral tilt = 8 functions

The secondary hydraulic valve block controls three functions of the combine.

NOTE: See detailed list of the valves (solenoids) in "Service - Electrical System".
