my blade clutch toggle finally went out so i bought a new toggle from "landscapesupplyonline" and put it in but my blade clutch still will not engage . before it went out here recently it would turn itself in the off position quite frequently . then i would turn the toggle back on and the blades would spin again . but this last time was the last time . now i am lost the clutch never slipped or hesitated to engage at all . any one got as clue what i need to do now ?
