PIVOTING DUAL LAND WHEEL FOR A PLOW Abstract of the Disclosure A land wheel assembly including dual wheels pivotally mounted on a vertically positionable arm of an implement such as a plow. When the arm is lowered and the plow is in the transport position the wheels can rock in a castering fashion about a pivotal axis having a substantial vertical component so that as the implement is turned around a corner, the wheels caster to reduce tire scuffing and stresses in the assembly. When the arm is raised to lower the implement to the ground-working position, the pivotal axis shifts, approaching a generally horizontal attitude and allowing the wheels to pivot up and down with respect to each other about the axis to provide an even plowing depth and reduce stresses throughout the assembly on uneven ground.
