Wacker BS50-4 and BS60-4 rammer tampers deliver outstanding performance - Add Wacker's exclusive WM 90 4 cycle engine to preferred vibratory rammer design in the industry and you have a winning combination. The WM 90 Wacker engine is specifically designed for rugged soil tamper applications. A 4 cycle Wacker dirt
tamper is designed for the compaction of cohesive, mixed and granular soils in confined areas.

Patent-pending low oil shutdown provides unique technology that protects the engine. When starting the BS50-4s or BS60-4s, should the electronic sensor detect no oil or low oil, a red flashing light signals the operator and the engine will shut off within about 10 seconds.

A unique three-stage air filtration system provides a virtually dust-free engine for longer life and improved durability.

This Wacker jumping jack tamper features a dedicated 4 cycle crankcase for increased durability and simplified maintenance

Wacker BS 50-4 and BS 60-4 dirt tamper features a unique crankcase breather system and a three-piece piston oil ring providing for lower oil consumption
