If you own an Iseki, Kubota, Hinomoto, Yanmar or Shibaura mini tractor, it is important to use the right oil to extend the life of your machine. It is crucial to use the right oil types to ensure that your mini-tractor keeps running smoothly and to prevent damage.
Engine oil
The engine oil for these mini tractors should always be 15W40. This is a multi-grade oil suitable for use in various weather conditions and temperatures. When you change the engine oil, make sure you add the right amount of oil and change the oil filter.
Another important factor to keep in mind when choosing the right oil for your mini tractor is viscosity. Viscosity refers to the thickness of the oil and can be indicated by the first number in the SAE rating. For most mini tractors, it is recommended to use an oil with a viscosity of 15W40, which means that the oil is suitable for use in temperatures from -15°C to 40°C. This keeps the engine running smoothly even in extreme temperatures.
In addition to engine oil, there are other types of oil needed for your mini-tractor. Transmission oil, for example, is an essential oil needed for the transmission to work correctly. For most mini tractors, it is recommended to use an SAE 80W90 GL-4 transmission oil. Designed specifically for use in transmissions, this oil provides excellent protection against wear and oxidation. Naturally, it is therefore applied as a hydraulic oil. In mini tractors, the gearbox oil and hydraulics are the same.
Front axle oil is also important for your mini tractor and is used to keep the front axle properly lubricated. An SAE 80W90 GL-5 front axle oil is recommended for most mini tractors. This oil provides excellent protection against wear and oxidation and keeps your mini tractor running smoothly.
Iseki
Iseki mini tractors have a diesel engine and it is recommended to use an engine oil of API category CF or higher. The oil must meet the JASO DH-1 or DH-2 specification.
Kubota
An engine oil of API category CF or higher is also recommended for Kubota mini tractors. It is recommended to use an oil that meets the specification of Kubota UDT or Super UDT.
Hinomoto
Hinomoto mini tractors also have a diesel engine and it is recommended to use an oil of API category CF or higher that meets Hinomoto’s specification.
Yanmar
Yanmar mini tractors have a diesel engine and the recommended engine oil is API category CF or higher. It is recommended to use an oil that meets the specification of Yanmar K-Hydro or Yanmar Super Universal Oil.
Shibaura
Shibaura mini tractors also have a diesel engine, and the recommended engine oil is API category CF or higher. It is recommended to use an oil that meets the specification of Shibaura S753 or S753H.
