Abstract
A flexible frame for a high clearance agricultural vehicle has left and right frame rails, an axle suspended beneath the frame rails, and a suspension system coupling the axle to the frame rails. Left and right vertical mounts are coupled to the frame rails. Upper and lower torque rods couple the axle to the vertical mounts with brackets. The suspension system also has a cross torque rod having a left end coupled to an inward facing bracket on the left vertical mount and a right end coupled to an inward facing bracket on the right vertical mount. Each of the upper, lower and cross torque rods are coupled to its respective torque rod brackets with rotatable joints. The rotatable joint permits angular rotation of the torque rod about its torque rod bracket.
