Technical Description

The Kubota R520S is a compact, versatile wheel loader designed for heavy-duty tasks with a 44.4 hp Kubota V2203-RP 4-cylinder diesel engine delivering power at 2600 rpm. It features a 0.8 cubic yard heaped bucket capacity with a bucket width of 5.8 ft (69.3 inches), providing efficient material handling. The loader’s maximum dump clearance is 8.7 ft, and it offers a reach of up to 12.2 ft from the swivel point, with a digging depth of 9.1 ft, making it suitable for diverse excavation and loading operations. Dimensionally, it measures roughly 15.3 ft in length with the bucket on the ground, 8.5 ft tall to the cab roof, and 5.8 ft wide over the tires, ensuring compact maneuverability. It has a wheelbase of 6.4 ft and ground clearance of 1.1 ft. The operating weight is approximately 8,980 lbs, contributing to stability and traction aided by its 15.5/60x18-8PR tires and a turning radius of 11.2 ft. The hydraulic system uses a gear pump with a flow capacity of 11.1 gallons per minute, operating at a relief valve pressure of 2958 psi, optimizing digging and lifting power. Its Load Sensing Transmission (LST) provides two forward and reverse gears, enabling a max speed of 12.5 mph for efficient site mobility. Additional features include 4-wheel drive, high dumping clearance, wet disc brakes, and an ergonomic operator cabin with ROPS/FOPS certification for safety and comfort during operation.
