Wheel Loaders

  • Warranty 2 year


Superb lifting performance

A long reach and high clearance paired with impressive lifting power make material handling easy. Lift and load to trucks with ease, while the superior reach makes pallet fork operations faster and more efficient.

Modern high-visibility cabin

The R40’s expanded cabin offers a panoramic view for easier and safer operation. The full glass door, and wide opening window provide excellent visibility to the left and right, while the rear window offers an unobstructed view when traveling in reverse.

Coupler options

Efficiently exchange attachments to meet the needs of the job at hand. Choose between mechanical or hydraulic skid steer style or hook and pin style couplers to get you on your way.

Simplified control layout

The R40 series features an updated interior layout focused on easier operation and visibility. All major switches are now located on the right side for quicker access. All major loader functions are on a single lever that is easy to operate with just one hand, both on the R540 and R640. The 2-step speed control switch lets you quickly change speeds, allowing you to operate at optimum efficiency for the task at hand.

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.

Tire options

Choose from a selection of quality tires to help you work on a variety of terrain or seasonal conditions. Kubota has three tire options, standard bias, industrial radial and winter tire.

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.

LED work lights

Bright LED work lights provide plenty of illumination for nighttime tasks.
