Honda GX390

The Honda GX390 is a premium grade petrol engine which provides maximum performance and efficient, dependable power. The first Yamaha engine was used on our chippers in 2020. Today it is widely used throughout the TOMCAT range on our gravity feed chippers, entry-level hydraulic-feed chippers, stump grinders, log splitters and tip trailers.

The following features makes this engine unique:

  • Ultra low fuel consumption
  • Extremely easy to start
  • Oil low sensor and auto cut-out
  • The intake mixture flow is optimised by the use of a swirl effect. It creates a uniform air/fuel mixture throughout the engine's combustion chamber, which increases power and increases the speed of combustion throughout the cylinder while simultaneously decreasing exhaust emissions and fuel consumption.
  • A large muffler is fitted to reduce noise from the exhaust.
  • The sleeve is made from cast iron to increase engine durability and decrease wear on the cylinder.
  • SUH3 high hear resistant steel is used to manufacture the exhaust valve. The entire surface of the valve is polished Tuffride® finish, which increases the hardness and decreases the friction through the valve.
