Header Tilt Controls and Components
Header Tilt Control Switches
The manual header tilt switch is located in the
hydro handle and is used to manually control
the header tilt angle. Consult your John Deere
Operator's Manual for explanation of the Contour
Master operation.
Header Tilt System
The header tilt hydraulic system consists of the
header tilt control valve, master cylinder, slave
cylinder, flow control, and relief valve. As the
combine levels, the carriage extends or retracts
the master cylinder, which sends oil to the slave
cylinder. The slave cylinder counter-rotates the
header. No electronic function is required for
this action to occur.
The operator can manually trim the header
angle with the header trim switch on the hydro
control handle. In the Contour Master mode,
the header angle is automatically trimmed by
activating the lateral tilt valve, which is coupled
to the master/slave circuit. In case the header
contacts the ground, a relief valve prevents
damage to the header and feeder house.
