A concrete finishing float for finishing wet concrete consists of a long, detachable handle assembly which is attached to a float by means of an incline adjusting mechanism. This mechanism allows the user from a remote location by the use of a long handled shaft to alter the incline of the float in relation to the handle assembly while the float is in use by axially rotating the handle assembly. The incline adjusting mechanism includes a rod which connects the handle receiving member to the float. Axial rotation of the handle causes the rod to move the float relative to the handle.

A tilting mechanism for an elongated concrete finishing float having a forward edge and a rear edge, comprising: (a) support means adapted for mounting on said float; said support means having an upper portion and a lower portion, a hinge connecting said support means upper portion to said support means lower portion for tilting motion therebetween along an axis running generally parallel to the longitudinal axis of said float; (b) an elongated shaft, rotatable connecting means for connecting said shaft to said support means upper portion whereby said shaft extends generally transversely and rearwardly of said float; and (c) a link having a first end and a second end, said link first end being adapted for pivotal connection to said shaft at a position spaced rearwardly from said rotatable connecting means; said link second end being adapted for pivotal connection below and rearwardly of said hinge for movement with said support means lower portion; (d) stop means which are associated with said hinge means; said stop means comprising inclined stops abutting each outer side of said support means lower portion; said inclined stops having upper stop surfaces; said support means upper portion having lower stops surfaces for stopping engagement with said upper stop surfaces; and (e) whereby rotational movement of said shaft produces tilting between said support means upper and lower portions which translates into tilting motion of said float with respect to said shaft.
