The phenomenal sales growth of enclosure equipped two-wheel-drive (2WD) tractors demonstrates that comfort and convenience are very marketable features. The operator comfort of the enclosure has created an appetite for corresponding ride quality.
Although the operator is subjected to acceleration in all three orthogonal directions; traditionally, tractor suspensions have isolated vibration only in the vertical direction. Measurements reveal that isolation of longitudinal acceleration provides the best compliment to the vertical suspension on 2WD tractors.
John Deere has developed a ride comfort package which provides the first bidirectional suspension offered on a 2WD tractor.
