Four-cycle rammers deliver outstanding performance

Add Wacker Neuson's exclusive WM 100 4-cycle engine to the preferred vibratory rammer design in the industry and you have a winning combination. The WM 100 engine is specifically designed for rugged rammer applications. These 4-cycle vibratory rammers are designed for the compaction of cohesive, mixed and granular soils in confined areas.

  • Patented low oil shutoff provides unique technology that protects the engine. When starting the unit, an electronic capacity sensor detects no oil or low oil and the engine will shut off within about 10 seconds.
  • Purge bulb evacuates air from the fuel line for easy starting.
  • The fuel valve and kill switch are integrated into the throttle lever to reduce complexity of operation.
  • Exclusive carburetor compensates fuel/air mixture for optimum performance and extended air filter life.
  • Dedicated 4-cycle crankcase for increased durability and simplified maintenance
  • Unique crankcase breather system and three piece piston oil ring provide for lower oil consumption.
  • Ignition and fuel shut off built into the throttle control provides simplified operation
  • Cast aluminum recoil start with oversized durable rope extends life in harsh environments
  • The guide handle's engineered shockmount system reduces HAV (hand-arm vibration) and improves operator comfort.

Standard Package – BS 50-4s
