A suspension assembly (100) for an agricultural machine (10), adapted to reduce bump steering. The suspension assembly includes a strut shaft (120), a hollow tube (160), a cushioning mechanism (180), and a force control pad (162). The strut shaft can have an elongated body (121) having a first end (122), a second end (124), and a middle portion (126), the middle portion defining a cutout (127). A wheel support (130) can extend from the strut shaft and can be adapted to carry a wheel (12). The hollow tube can be at least partially disposed around the strut shaft and can be adapted to allow longitudinal motion of the strut shaft. The cushioning mechanism can cushion the longitudinal motion of the strut shaft. The force control pad, which can be connected to the hollow tube, can be engageable to the flat area (128) of the strut shaft. The force control pad can impart or resist rotational force when engaged to the strut shaft.
