Adjustable hitches for coupling surface conditioning tools and work machines

Abstract

An apparatus comprises a first elongate member configured to detachably and fixedly couple with a work machine in a tow-behind configuration, a two-axis joint member coupled with the first elongate member at a first joint permitting rotation of the two-axis joint member relative to the first elongate member about a first axis of rotation, a rigid frame portion including a second elongate member coupled with the two-axis joint member at a second joint permitting rotation of the second elongate member relative to the two-axis joint member about a second axis of rotation perpendicular to the first axis of rotation and a third elongate member extending perpendicular to the second elongate member, a surface conditioning tool extending parallel to the third elongate member and coupled with the rigid frame portion at a third joint and at a fourth joint permitting rotation of the surface conditioning tool relative to the rigid frame portion about a third axis of rotation parallel to the second axis of rotation, and a variable-length tool coupling member coupled with the rigid frame portion at a fifth joint and coupled with the surface conditioning tool at a sixth joint.
