Call for Price




  • Clean-running Kubota Engine (Interim Tier IV): Powerful and dependable, the R520S diesel engine delivers superior horsepower and performance. It offers low noise and vibration levels, exceptional fuel efficiency, and complies with the EPA's 2008 interim Tier IV emissions regulations.
  • Load Sensing Transmission (LST): To operate more efficiently, this innovative feature enables our wheel loaders to automatically shift from high speed/low torque to low speed/high torque as load conditions vary. For optimal operation in tight spaces, the travel speed limiter reduces maximum travel speed with just a touch of a button, while maintaining full performance of the auxiliary hydraulics.
  • Limited Slip Differential: Kubota's 4-wheel drive lets you outmuscle challenging terrain, such as mud, sand, and snow. When loose or soft terrain causes one front wheel to lose its grip, the Limited Slip Differential transfers that wheel's power to the opposite wheel to restore traction.
  • Superior Lifting Capacity: A strong feature that provides smooth lifting and dumping of heavy loads into truck beds.
  • Auxiliary Hydraulics---A Standard Feature: With the hydraulic valve and the control lever built-in on both our models, you'll save time and money whenever you need to hook up a hydraulically operated attachment.
  • Lower Sound and Vibration: To enhance operator comfort, both models utilize a new engine mount design, a helical gear, and an F-shaped fan to significantly reduce overall noise and vibration.
  • Automatic Parking Brake: This safety feature automatically engages the parking brake whenever the engine is turned off. Particularly useful when our wheel loaders are parked on steep slopes or transported by truck.
