500 Series
Technical specification
Fuel requirements
Diesel fuel must meet the Ultra low sulfur diesel fuel requirements. Never add petroleum or any additives to diesel fuel.
To comply with emissions standards, use only ULSD fuel with sulfur content less than 15 ppm / 0,0015 %.
Engine oil requirements
Use only high quality engine oil with the viscosity rating
recommended by the engine manufacturer with API service
class SJ or higher. See also Kubota Operator’s Manual. In cold
conditions use high quality multi grade oil.
Tires
The loader can be equipped with different type of tires for different operating conditions. Grass pattern (GR) tires will
damage the ground surface less than tractor (TR) tires, but provide less traction.
For the best stability and controllability, always use the largest tires possible. Tires that are narrower than the standard
tires are intended for special purposes only with width restriction on the machine. Use only tires and rims that meet
the original specifications and dimensions to avoid potential issues with load capacity, tire size, or bearing load on
drive motors. Consult your dealer if further information is needed. Special tires, such as studded wheels may also be
available. Consult your dealer for further information.
