The Kubota KX61-3 and KX71-3 Mini Excavators are compact and efficient machines designed for construction, landscaping, and utility applications requiring maneuverability and reliability. With operating weights of approximately 2.5 tonnes for the KX61-3 and 2.8 tonnes for the KX71-3, these excavators balance power and versatility in a size class that can easily access tight job sites. Both models are equipped with Kubota’s proven V1505 diesel engine, offering reliable performance, low fuel consumption, and reduced emissions.

The KX61-3 features a transport width of about 1.4 meters, making it well-suited for confined working conditions. The KX71-3, slightly larger at 1.5 meters wide, delivers increased stability and performance with deeper digging reach and enhanced breakout force. Both machines are designed with Kubota’s advanced hydraulic system for smooth, responsive operation, and provide a comfortable operator environment with ergonomic controls and ROPS-certified protection. With bucket capacities ranging around 0.07–0.08 m³ and efficient auxiliary hydraulics, they support a wide range of attachments for digging, trenching, grading, and lifting.

The workshop repair manual covers comprehensive service procedures for both models, including detailed sections on the machine body, hydraulic circuits, pump and control valve assemblies, cylinders, swivel motors, rotary joints, and the Kubota Intelligent Control System (ICS). It also includes wiring diagrams, hydraulic schematics, torque specifications, lubrication schedules, and troubleshooting flow charts. This ensures technicians and operators can perform accurate diagnostics, routine maintenance, and full system repairs to maintain peak performance and reliability.
