ENGINE Highly trusted, efficient Kubota E-TVCS diesel engine for reduced exhaust emissions, noise and vibration. HYDRAULICS Two variable pumps enable simultaneous operation of the boom, arm, bucket and the swivel for continuous high-performance digging and dozing. VERSATILITY Kubota’s zero tail swing for excellent stability, smooth control and operation in confined spaces without need for additional weights. Tracks can adjust between 1300mm to 1500mm to easily navigate narrow spaces or optimise stability when using heavy attachments.
PERFORMANCE The powerful and well- balanced arm and bucket offers powerful and fast workability with excellent stability. COMFORT The U20-3 α cab is ergonomically designed for smooth operation. Flat floor design with conveniently placed levers (including a 2-speed travel switch on the dozer lever) ensures optimum comfort. Wrist rests and a high back seat also enable smoother control and reduce operator fatigue. SAFETY ROPS (Roll Over Protective Structure) and FOPS (Falling Objects Protective Structure) Level 1.
