Articulating pitch-adjustable hitches for surface conditioning tools

An apparatus comprising:

• a hitch assembly including a forward lateral member, a rearward lateral member, a first longitudinal member, a second longitudinal member and a lifting member which are coupled together to form a laterally-articulating pitch-adjustable frame, wherein
• the forward lateral member is coupled with the first longitudinal member by a first joint and is coupled with the second longitudinal member by a second joint,
• the rearward lateral member is coupled with the first longitudinal member by a third joint and is coupled with the second longitudinal member by a fourth joint,
• the lifting member is coupled with the rearward lateral member by a first flexible rigging member and a second flexible rigging member,
• the laterally-articulating pitch-adjustable frame is moveable between a first position in which the frame is left-leaning and a second position in which the frame is right-leaning, and
• the lifting member is adjustable over a first range to vary an amount of slack in at least one of the first flexible rigging member and the second flexible rigging member and over a second range to raise and lower the rearward lateral member.
