Hybrid Link Design

Hybrid Link Design

The well balanced cylinder position of the Kubota Z link system combines the advantages of both Z link and parallel link systems. You get strong bucket force when excavating and grading, and a lift path almost parallel to the ground for superior reach and lifting.

Articulating and Oscillating Frame

Articulating and Oscillating Frame

Our wheel loaders are most often operated in heavy terrain, so we include features for top performance in these conditions. Articulation allows the rear tires to follow the same track path as the front tires for greater maneuverability and control of the loader. Rear frame oscillation is intentionally chosen over rear axle oscillation for superior workability in uneven ground conditions.

Kubota Engine with Automatic Regeneration

Kubota Engine with Automatic Regeneration

The Common Rail System electronically controls the fuel injection timing and amount in stages, rather than all at once, for optimal combustion. The results are great efficiency, better fuel economy and less engine noise. Its combination with the Exhaust Gas Recirculation (EGR) and Diesel Particulate Filter (DPF) Muffler reduces emissions to make the R530 Tier 4 Final compliant.

Kubota’s original automatic regeneration system automatically burns accumulated particulate matter (soot) in the DPF muffler to keep it clean. For operational reasons, regeneration can be turned off and manually accomplished at a more appropriate time.

AUX Service Ports

AUX Service Ports

Conveniently located on the rear of the attachment quick coupler flat face, no drip couplers provide easy access to power your hydraulic attachments. Auxiliary ports are plumbed separately from hydraulic quick coupler plumbing.
