ABSTRACT:
An idler sheave assembly for a lawn mower which is simple in construction and which maintains the tension in the mower drive belt at any vertical position of the mower. The idler sheave assembly is supported on a U-shaped yoke which is pivotally supported on the mower tow bar linkage. The assembly includes a mule sheave fixed to the yoke and a rock sheave rotatably supported on an annular sleeve. A torsion spring is spirally wound around the sleeve having one end fixed relative to the yoke and a free end rotatably biasing the rock shaft to tension the mower drive belt. The free end of the spring is received in an elongated slot in the yoke, providing a simple belt tension gage. The belt tension is adjusted by adjusting the angular position of the U-shaped yoke relative to the mower.
