Abstract
A portable vibratory screed machine is provided with a vibration restraint operable to reduce undesirable vibration of the engine and to extend the life of the engine. The portable vibratory screed machine includes a machine frame having a reference structure. The machine further includes an engine mounted on the reference structure via a mount that surrounds a drive shaft that is driven by the engine's output. A vibratory assembly remotely located from the engine is powered by the engine to vibrate a screed plate. The vibration restraint directly couples the engine housing to the reference structure at a location that is spaced apart from the mount.
