CONCRETE FINISHING MACHINE WITH ADJUSTABLE FLOAT
A concrete finishing machine includes a base portion and an extendable and retractable boom mounted at the base portion, and a finishing head mounted at a distal end of the boom. The finishing head includes (i) a float pivotally attached at a frame of the finishing head via a plurality of linkages, (ii) a float actuator that, when actuated, imparts pivotal movement of the linkages to adjust the float relative to the frame, and (iii) a surface finishing element. The concrete finishing machine is operable to selectively position the float or the surface finishing element at the concrete surface during extension or retraction of the boom. Responsive to a sensing device, the finishing head is maintained at a desired level or position above the concrete surface with the float or the surface finishing element at the concrete surface during extension or retraction of the boom.
