ABSTRACT:
A walk-behind rotary tiller includes an engine having an output shaft on which is mounted a first pulley. A second pulley is mounted on a countershaft and connected to be driven from the first pulley by a drive belt. The engine is mounted for adjustment toward and away from the counter shaft to compensate for belt stretch and to facilitate belt replacement. A guard encloses the belt and has its forward end pivotally supported on a bracket fixed to the engine by a fastener which also serves to retain a belt guide in place. The rear end of the belt guard is supported for swinging about the forward connection, when the motor is adjusted, by a bent rod having one end pivotally received in the guard and a parallel, axially offset second end serving to pivotally connect a bracket, having a drag stake and wheel assembly fixed thereto, for movement between raised and lowered positions for respectively disposing the drag stake and wheel assembly in transport and working positions.
