Spindle assembly

A spindle assembly for the cutter blade of a rotary lawn mower including an open-ended, generally cylindrical housing mounted on said lawn mower with its axis generally vertical and having an inner surface, a spindle disposed coaxially within said housing and extending from the open opposite ends thereof, said spindle being spaced from the surface of said housing to define a gap therebetween, first and second bearing means disposed in a spaced apart relation within said housing and respectively adjacent the lower and upper ends thereof and between said spindle and said housing for rotatably supporting said spindle relative to said housing, first seal means disposed below said first bearing means and in surrounding relation to said spindle for sealing the lower end of said housing and second seal means disposed above said second bearing means and in surrounding relation to said spindle for sealing the upper end of said housing, and bushing means disposed below said first seal means and having an outer periphery in proximity to the inner surface of said housing for protecting said first seal means, rotary cutter blade means fixed to the lower end of said spindle and a coupling means adjacent to the upper end thereof and adapted to be connected to a rotary power source, the gap between said spindle and said housing being substantially filled with a liquid lubricant.
