Abstract
In a small tractor, there is provided a suspension system for mounting a small internal combustion engine on the framework of the tractor that includes a pair of vibration-dampening engine mounts substantially on the center of gravity of the engine and an engine mount for the main engine drive shaft. The motor mount for the shaft is incorporated in a pulley device that includes a pulley concentric with but spaced from the shaft so that the vibrations of the shaft and engine are not transmitted to the pulley. The pulley is supported by a journal carried on the tractor frame and the pulley is connected to the shaft through an annular layer of elastomer material that is fixed to rotate both with the pulley and the shaft and which dampens any shaft or engine vibration that might otherwise be transmitted to the pulley and to the frame.
