The Komatsu WB97R and Its Market Position
The Komatsu WB97R loader backhoe was introduced in the early 2000s as part of Komatsu’s European-built WB series, designed to compete directly with the Case 580/590 and Caterpillar 428/432 models. With a focus on durability, hydraulic performance, and operator comfort, the WB97R featured a side-shift backhoe, four-wheel drive, and a turbocharged diesel engine producing around 100 hp. Komatsu, founded in Japan in 1921, has sold millions of machines globally, but its loader backhoe segment has remained more niche compared to its dominance in excavators and dozers.
The WB97R was built in Italy and tailored for European and Australian markets, where side-shift backhoes are preferred for trenching along walls and fences. Its design emphasizes mechanical simplicity and robust steel construction, making it attractive for farm work and rural contractors.
Terminology Notes
Compared to the Case 580SL or Cat 428B, the Komatsu WB97R offers:
One farmer in New South Wales purchased a 2003 WB97R with 5,000 hours and found it ideal for fencing, trenching, and general farm work. He noted that the side-shift feature allowed him to dig close to tree lines without repositioning, saving time and fuel. Another contractor in Victoria shared that the machine’s loader arms were stronger than his previous Case 580, especially when lifting pallets of bricks.
A technician in Queensland emphasized that the WB97R’s hydraulic system was easy to service, with accessible filters and minimal electronic interference. He recommended using OEM filters and checking the side-shift wear pads annually.
Recommendations for Buyers
The Komatsu WB97R is a solid alternative to Case and Cat backhoes, especially for operators who value mechanical simplicity and side-shift versatility. While it may not match the resale strength or dealer network of its competitors, its performance and reliability make it a smart choice for farm work and rural contracting. With proper inspection and parts planning, the WB97R can deliver years of dependable service in demanding conditions.

Terminology Notes
- Side-Shift Backhoe: A backhoe that can slide laterally along the rear frame, allowing trenching close to obstacles without repositioning the machine.
- Powershift Transmission: A gearbox that allows gear changes without clutching, improving speed and control.
- SL (Super Loader): A designation used by Case for models with enhanced lift and breakout force.
- Extendahoe: A telescoping dipper stick that increases reach and dig depth.
Compared to the Case 580SL or Cat 428B, the Komatsu WB97R offers:
- Strong hydraulic breakout force, especially in the loader arms
- Excellent visibility from the cab, with large glass panels and ergonomic controls
- Reliable side-shift mechanism with minimal wear over time
- Simplified electronics, reducing diagnostic complexity
- Parts availability, especially in North America
- Resale value, due to lower brand recognition in the backhoe segment
- Cab refinement, which some operators find less comfortable than Cat’s deluxe interiors

Recommendations for Buyers
- Inspect Side-Shift Rails: Look for wear or binding in the lateral slide mechanism.
- Check Transmission Response: Powershift units should shift smoothly under load.
- Verify Hydraulic Pump Output: Use flow meters to confirm performance at full throttle.
- Source Parts in Advance: Identify local dealers or import channels for filters, seals, and hoses.
- Compare Total Cost of Ownership: Include fuel consumption, service intervals, and resale projections.
