Mini-concrete trowel attachment assembly
A mini-trowel attachment assembly having a rotary disk with a plurality of screw holes disposed therein with a plurality of replacement blades secured therein by a plurality of screw members. The plurality of replacement blades include at least a pair of elongated slots that allows the replacement blades to be adjusted slightly inward of an annular peripheral edge of the rotary disk. A free-wheeling self-lubricating bearing assembly having a first non-rotary bearing and spacer ring member attached to the rotary disk and a second free-wheeling member attached to the first non-rotary bearing and spacer ring member that freely rotates when it engages wall structures and upstanding obstructions in concrete surfaces. Also, the elongated slots allows the plurality of replacement blades to be adjusted slightly inward of an annular peripheral edge of the free-wheeling self-lubricating bearing assembly.
