Header Height Control Theory Of Operation

The header height control system is an electro-hydraulic system that maintains the left and right toolbar height so row units are maintained at optimum height for picking cotton.

Header height control calibration procedure should be performed at the beginning of each season, or if a component of the system is replaced. (See Header Height Control Calibration Procedure in this section).

Height adjust knobs (A) allow the operator to adjust and maintain the optimum height for the row units on the plants. Height can be "locked" into the system through the tachometer if desired. (See Header Height Control Lock Procedure-address 35 in this section).

Rate response knob (B) allows the operator to control how fast the row units react (raise/lower) to changing ground conditions while in the height sensing mode of operation. (See Header Height Control Rate Response Adjustment in this section).

Header height control system is activated when the operator lowers units using the raise/lower all units button (C) when units are engaged. System is deactivated when the operator raises the units using the raise/lower all units button.

Right-hand or left-hand row units may be lifted individually by pressing their respective button (D). When using these buttons, header height control is deactivated only on the row units being lifted. Header height control is reactivated to those units when they are lowered using the raise/lower all units button (C).

EXAMPLE: Press corresponding button to lift right-hand or left-hand units to desired height, release button. Press and release the bottom of raise/lower all units button to lower units to their preset height and resume automatic operation.
