ROTARY MOWER SPINDLE BRAKE

摘要

A braking mechanism for use with rotary lawnmowers utilizing a vertically extending spindle having a lower end upon which is attached a mower blade and having an upper end mounting a driven sheave. Such sheave being provided with a surface spaced from a stationary surface and being provided with a friction lining separating the two surfaces. Such sheave being threadably engaged with a collar splined to said spindle so that upon termination of power to said spindle, said sheave rotates relative to said collar bringing such surfaces into frictional engagement with said friction lining for decelerating said spindle.
