Claims11
An attachment leveling assembly comprising;
- a transport pivot axle assembly removably and rotatably attached to a towable attachment assembly, said transport pivot axle assembly comprising at least two transport axle portions configured to independently rotate about a lateral axis in response to motion of at least two independently operated hydraulic cylinders extending between the towable attachment assembly and the at least two transport axle portions;
- at least two wheel assemblies, wherein each wheel assembly is removably and rotatably attached to one of said at least two transport axle portions, said at least two wheel assemblies configured to independently rotate about a longitudinal axis within restraint limits, in response to ground contact and rotation of the transport axle assembly;
- wherein said at least two independently operated hydraulic cylinders are configured to respond to control signals from an attachment leveling assembly control system.
