Abstract:
1. An agricultural vehicle comprising: a right front wheel suspension assembly comprising a first strut assembly and a first dual action hydraulic cylinder, wherein the first strut assembly is connected to the vehicle at a first pivot and is connected to a right front wheel, and wherein the first hydraulic cylinder is operationally connected to the first strut assembly at a point distal from the first pivot and is also operationally connected to the vehicle such that motion of the first strut assembly around the first pivot is affected by action of the first hydraulic cylinder; a right rear wheel suspension assembly comprising a second strut assembly and a second dual action hydraulic cylinder, wherein the second strut assembly is connected to the vehicle at a second pivot and is connected to a right rear wheel, and wherein the second hydraulic cylinder is operationally connected to the second strut assembly at a point distal from the second pivot and is also operationally connected to the vehicle such that motion of the second strut assembly around the second pivot is affected by action of the second hydraulic cylinder; a left front wheel suspension assembly comprising a third strut assembly and a third dual action hydraulic cylinder, wherein the third strut assembly is connected to the vehicle at a third pivot and is connected to a left front wheel, and wherein the third hydraulic cylinder is operationally connected to the third strut assembly at a point distal from the third pivot and is also operationally connected to the vehicle such that motion of the third strut assembly around the third pivot is affected by action of the third hydraulic cylinder; a left rear wheel suspension assembly comprising a fourth strut assembly and a fourth dual action hydraulic cylinder, wherein the fourth strut assembly is connected to the vehicle at a fourth pivot and is connected to a left front wheel, and wherein the fourth hydraulic cylinder is operationally connected to the fourth strut assembly at a point distal from the fourth pivot and is also operationally connected to the vehicle such that motion of the fourth strut assembly around the fourth pivot is affected by action of the fourth hydraulic cylinder; and a pair of dual valves that are operably associated with the right front wheel, right left wheel, left front wheel and left rear wheel suspension assemblies.
