KUBOTA R420S WHEEL LOADER

Technical Description

The Kubota R420S is a compact wheel loader featuring a robust 3-cylinder Kubota D1503-TRP-1 diesel engine with a displacement of approximately 91.6–92 cu in (1,497 cc) that produces 39.5 hp (29 kW) at 2,600 rpm. It offers an operating weight of around 6,724 to 7,450 lbs (3,050–3,379 kg) depending on configuration, with 4WD available to provide enhanced traction and stability. The loader’s rated bucket capacity ranges from 0.5 to 0.75 cubic yards, with a bucket width near 60 inches (around 5 ft or 1.5 m) and a dump clearance at max raise of approximately 7.3 ft (2.2 m). Designed for maneuverability, it has a wheelbase around 5.9–6 ft (1.8–2 m), a transport length of about 13.7–15.6 ft (4.2–5 m), and a width over tires near 5 ft (1.5 m). The hydraulic system features a gear pump with a flow capacity of roughly 11 gpm (42 l/min) and relief valve pressure close to 2,958 psi, enabling smooth and responsive loader operation. Transmission is a Load Sensing Transmission (LST) with 2 forward and 2 reverse gears, achieving a maximum travel speed of about 12.5 mph (19 kph). The R420S also includes loader-specific features like a hydraulic matching system for fast and powerful digging. Safety and durability are enhanced with options for ROPS/FOPS certified canopy or cab configurations, an oscillating body for stability on rough terrain, and wet disc brakes. Compact yet powerful, the Kubota R420S is suitable for diverse construction, landscaping, and utility tasks requiring efficient digging and material handling in confined spaces.
