Kubota KH36, KH41, KH51, KH61 Excavator Workshop Repair Manual

The Kubota KH36, KH41, KH51, and KH61 Mini Excavators are compact and reliable machines designed for light-to-medium duty excavation tasks in construction, landscaping, and utility applications. With operating weights starting at around 1.3 tonnes, these excavators offer maneuverability and efficiency in confined job sites while maintaining Kubota’s reputation for durability and ease of service. Their compact dimensions make them ideal for transport and access to restricted spaces.

The KH36 is powered by the Kubota Z620KW engine rated at 8.8 kW, delivering efficient performance for smaller excavation jobs. The KH41 features the more powerful Kubota D950-BH1 engine, rated at 13.2 kW, offering increased digging force and productivity. Both models feature a 0.04 m³ bucket capacity and compact transport widths of under 1 meter, with track widths ranging between 200–230 mm for stable operation. While specific specifications for the KH51 and KH61 are less readily available, they continue the progression in the KH-series with increased operating capacities and durability improvements for more demanding excavation work.

The workshop repair manual provides complete system coverage, including the machine body, hydraulic system, electrical system, and engine. Step-by-step repair instructions, torque specifications, lubrication schedules, and schematic diagrams support accurate troubleshooting and maintenance. With detailed service coverage, the manual ensures that operators and technicians can maintain peak machine performance and extend the life of these excavators.
