The Kato Brand: A Snapshot of Strength and Simplicity
Kato Works Co., Ltd., a Japanese manufacturer with roots dating back to the 1890s, has long been known for building robust, mechanically straightforward excavators. Their machines—especially models like the 1220 SE II and 1250 VII Exceed Series—earned reputations for durability and ease of repair. In markets like Australia, South Africa, and parts of China, Kato excavators were once common sights on job sites, praised for their simplicity and reliability.
Strengths of Kato Excavators
Despite their mechanical strengths, Kato machines have struggled with parts availability and dealer support—especially in North America. Several operators reported waiting months for components like drive motors or final drives. In some cases, dealers disappeared entirely, leaving owners with no access to technical help or replacement parts.
Common issues include:
One operator in Texas purchased a used Kato 1220 SE II from a Louisiana parish. After a cylinder block failure, he spent months searching for parts, even considering custom machining at a cost of $2,000. He explored salvage yards, contacted Australian suppliers, and considered importing used components. The experience highlighted the risks of owning a machine with limited regional support.
Australia’s Kato Legacy
In the 1970s and 1980s, Australia was a strong market for Kato. Dealers like Blackwood Hodge distributed the machines widely, and companies like Excavator World and Excawreck still offer used parts. Operators recall models like the 770, which had a famously complex control layout—“more levers than a grader,” as one veteran put it. Despite aging fleets, many Australian contractors still run Kato machines as yard units or backup rigs.
China’s Mixed Experience
In southern China, Kato excavators are still in demand, with long wait times for new units. However, in northern regions, poor dealer support and limited parts access have pushed buyers toward brands like Komatsu and Hitachi. A factory in Jiangsu was established to support local demand, but sales volume remains modest compared to top-tier manufacturers.
Suggested Solutions and Advice
Kato excavators have earned their place in the history of heavy equipment—machines that dig hard, last long, and ask little in return. But for modern contractors, the brand’s limited support network and parts scarcity can turn a reliable workhorse into a stranded investment. For those willing to chase down parts and lean on international contacts, Kato remains a viable option. For others, it’s a reminder that even the toughest machines need a lifeline when things go wrong.

Strengths of Kato Excavators
- Rugged construction suitable for harsh environments
- Straightforward mechanical systems that allow field repairs
- Long service life when properly maintained
- Interchangeable parts across certain models
- Good performance in demolition, trenching, and general earthmoving
- Final Drive: The gear assembly that transmits power from the hydraulic motor to the tracks.
- Cylinder Block: The central housing of the engine where pistons move; damage here often requires full engine rebuild or replacement.
- Ring Gear: A large gear inside the final drive; custom fabrication is costly but sometimes necessary when parts are unavailable.
Despite their mechanical strengths, Kato machines have struggled with parts availability and dealer support—especially in North America. Several operators reported waiting months for components like drive motors or final drives. In some cases, dealers disappeared entirely, leaving owners with no access to technical help or replacement parts.
Common issues include:
- Long lead times for parts
- Limited dealer networks in North America
- Difficulty sourcing components for older models
- High cost of custom-fabricated parts
- Lack of technical documentation for legacy machines

Suggested Solutions and Advice
- If purchasing a used Kato, verify parts availability before committing
- Build relationships with international suppliers—Australia remains a strong source for legacy parts
- Consider machines with interchangeable components across models
- Document all part numbers and service history for future reference
- Use custom fabrication only as a last resort due to cost and lead time
- Final drive condition: Check for gear wear and oil contamination
- Hydraulic motor compatibility: Some models share motors with other Japanese brands
- Undercarriage wear: Track chains and rollers may be sourced from Korean or Italian suppliers
- Electrical system: Older models may lack standardized wiring diagrams
