A lawn mower having a rotation drive connection assembly including a reel shaft having concially shaped opposite ends and an interior threaded length in each of the opposite ends. A drive coupler with a conical shape on one end thereof mates with one of the reel conical ends and has a threaded opening for receiving a screw extending into the shaft for holding the coupler thereon. A spline is on the end of the coupler opposite its one end, and there a drive member with a spline engaged with the coupler spline, all for rotating the shaft. A counter-balance is threadedly attached in the assembly adjacent the end of the shaft opposite the coupler location.

[ What is claimed is:] [1.] A lawn mower having a rotation connection assembly comprisinga rotatably mounted mower reel shaft having a longitudinal axis and a conically-shaped end portion extending co-axially with said axis,said shaft end portion having a threaded opening extending co-axially with said axis,a coupler having a conically-shaped wall defining a bore of the shape of said shaft conical end portion and extending co-axially with said axis and said wall being disposed in friction rotation drive contact with said concially-shaped shaft end portion and having a shoulder disposed transverse to said axis,a screw in said coupler and being threadedly connected with said shaft threaded opening and arranged to bear against said coupler shoulder in a manner to hold said coupler releasably mounted on said shaft and rotatable therewith through the rotation friction drive between the conical shapes,said coupler having a cylindrical opening co-axially disposed relative to said conical bore and at the end of said coupler opposite said one end and being disposed beyond said shaft and having a spline thereon, anda drive member with a splined shaft thereon releasably rotationally splined with said coupler at said opposite end of said coupler.
