Abstract
A tractor electronic linkage control system comprises electronic draft force and linkage position sensors (30, 33) and manual draft force and linkage position controls (31, 32). An electronic control unit 17 derives draft and position error signals and continually compares them to determine whether the system is to operate in draft control mode, where the draft error signal governs linkage movement, or position control mode, where the position error signal governs linkage movement.
