Abstract: A rear wheel assembly replaces single large rollers normally used on the rear of forty-foot field finishing land planes. The assembly provides units having one pneumatic tired wheel mounted to swivel under a narrowed platform at the front and two pneumatic tired wheels on an axle at the rear. The wheel assembly attaches by swivel stud to original swivel stud receivers at the back frame of the land plane.

Abstract: A field finishing land plane has a V-shaped, horizontally oriented frame converging at a front end affixed pivotal to steerable rollers in a yoke fastened to a tow tongue. The pivotal front is housed in a protective shielding. A cross member that attaches to the wide section of the V frame at the rear of the land plane extends outward from the V ends on each side. The outward extensions have individual rollers attached to swivel at the outer ends. Supported by internal framing and operated hydraulically, pneumatic tired, retractable road wheels can be raised for field use of the land plane and lowered for on-road towing. For field use with the road wheels raised, the land plane of this invention rests on the front steerable rollers and on the rear swivel rollers so that a long crosswise scooping bucket located centrally under the main frame of the land plane makes ground contact. For road safety during towing with road wheels down, the long crosswise scooping bucket has rotatable end sections.
