Common Applications

  • Commercial Rammers


Developed Specifically for Rammer Applications

  • Designed to power 110-lb. to 175-lb. rammers at multiple altitudes with ease.
  • More power than the GX100, with a compact, lightweight engine footprint for additional versatility in frame mounting

Fuel Efficient, High Output Operation

  • OHC design developed specifically for increased efficiency
  • Optimal power transfer for better fuel efficiency

Smooth Performance

  • Precision engineered components result in lower vibration
  • Ball bearing supported crankshaft for greater stability

Exceptionally Quiet

  • New design reduces operation noise by 1dB over the original GX100
  • Compact exhaust system is 22mm narrower than the GX100, yet quieter
  • Maintenance-free, low-noise timing belt creates a smaller, lighter and quieter engine
  • Reduced mechanical noise due to light weight, noise-reducing materials
  • Forged steel crankshaft and rigid crankcase

Proven Reliability

  • A special cast-iron cylinder sleeve and a high carbon-steel, dual-ball bearing crankshaft provide improved engine strength for rammer applications.
  • The recoil starter and fan cover are even more robust through the incorporation of steel in the design.
  • Innovative lubrication system with a dual-breather chamber optimizes engine lubricating performance in most rammer operating conditions
  • Oil Alert
  • New carburetor chamber coating and carburetor filter help to protect against fuel impurities
  • High quality materials, fit, and finish
  • 3-Year Limited Warranty

Easy to Use and Maintain

  • Simple throttle control
  • Easily accessible spark plug

Easy Starting

  • Heavy duty recoil starter
  • Ergonomic, easy to grip recoil rope design
  • Automatic mechanical de-compression system

Emissions Compliant

  • CARB and EPA compliant
  • No catalyst necessary
