Horse Power 8.0 - 12.0 PS
Weight 68 - 123 kg

Horizontal Diesel Engine
The all new Yanmar horizontal water-cooled diesel engine.
Guaranteed powerful and efficient with 12PS, 9PS and 7PS available in the Philippine market.


  • Less Fuel Consumption with Direct Injection

    Yanmar injection system > Less Fuel Consumption > Save money
    Making the machine economical and helps reduce expenses with the use of Yanmar injection technology (direct injection)

  • Faster and More Torque

    Used with high technology so best performance is guaranteed.
    Using Toroidal piston can result to more torque that farmers can rely to during operation in uphill or deep and muddy fields.

  • 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.

  • Brighter Lamp

    During night operation, lamp is very useful to operators. Yanmar re-design this new generation of horizontal diesel engine making the lamp brighter for safe operation.
