Powerful, Durable, and Worth

Perfect prime diesel engine with the high-pressure fuel pump in advanced design makes you ensure that the engine operates smoothly.

Extreme durability

Cylinders with the special substance provide 5-times durability. Crankshaft is developed to increase the size for the better strength, and also increase the size and number of craft shank bearing in order to load more weights, and better resist to the friction of engine.

Two-Legged Governor Helps Miring

The set of two-legged governor helps the engine start up quicker and not easy to shut down even the low speed engine. This helps the engine operating continuously when it is mired in the mud.

Direct Injection





More economy direct injection system

“Direct Injection” system is to spray the oil through the nozzle directly into cylinders. It helps reducing the engine power and heat. The energy is fully used up and the high injection pressure and horsepower are provided and also the increasing energy-saving.

Lower Engine Vibration

High vibration of engine results to operator’s fatigue. Yanmar’s dual balancer can make a big difference.
It helps in the reduction of engine’s vibration to make operation easier and less exhausting especially.

Less Engine Noise

Yanmar uses large muffler to lessen the engine noise. More engine noise may result to uncomfortable operation and can also lead to operator’s impaired hearing.
