About the Komatsu WA380
The Komatsu WA380 is a mid-size wheel loader in the 18–21-tonne operating weight class, in production since 2000 and currently in its WA380-8 generation. It is powered by a Komatsu SAA6D114E-6 Tier 4 Final engine producing 198 hp and standard bucket capacity is 3.8 m³. The WA380 is a versatile articulated wheel loader positioned between the smaller WA320 and the larger WA430, making it suitable for a broad range of aggregate handling, construction site logistics, and light earthmoving applications. KOMTRAX telematics is standard from the WA380-7 generation.
Where it earns its keep
The WA380 is a common machine in European aggregate processing plants, construction materials depots, and municipal yards. Dutch and Belgian asphalt mixing plants use it for aggregate stockpile management and cold-mix feeder loading. German construction sites use it as a versatile materials handler for moving precast concrete panels, pallets of materials, and bulk aggregates. Municipal authorities across Benelux use it for road salt spreading in winter maintenance operations with a spreader body attachment. Its fuel efficiency and broad attachment compatibility make it a cost-effective choice for mixed-duty applications.
What to look for when buying used
The WA380's axles are generally robust but inspect the front axle oil for discolouration or metal particles. Front axle planetary gear failures can be expensive and are often preceded by contaminated axle oil. Check the articulation joint and steering cylinder condition on machines with high accumulated cycle counts. The engine's air-intake pre-cleaner and air filter element should be inspected carefully: aggregate environments are particularly harsh on air filtration, and reduced filter life accelerates engine wear. Request KOMTRAX data to review fuel consumption and idle time: a high idle percentage on a wheel loader often indicates inefficient site operation rather than a machine fault.
Where the market sits
The WA380 competes with the Caterpillar 966M and Volvo L120H. Komatsu's WA380 has historically offered slightly lower residual values than Cat 966M equivalents, making it attractive to price-conscious buyers who prioritise value. The used WA380 market across Benelux and Germany is active, with a healthy supply of well-maintained machines from aggregate producers and construction material distributors. Prices for the 2014–2022 generation are currently at competitive levels, supported by consistent demand from the aggregate and recycling sectors.
Common problems at high hours
Front axle planetary gear failure is the most expensive risk on the WA380, typically manifesting between 7,000 and 10,000 hours with a metallic whine under load. Full axle rebuild runs €10,000–€14,000. The SAA6D114E-6 engine's exhaust gas recirculation cooler can develop internal leaks above 8,000 hours, contaminating coolant with soot and causing progressive overheating; replacement costs approximately €3,800. Independent drivetrain workshops servicing the Benelux aggregate sector flag the WA380's torque converter seal as a known weak point that leaks transmission oil into the converter housing, with repair costs of €2,500–€4,000 if addressed before secondary damage occurs. Articulation joint pin wear accelerates sharply on machines used in tight stockyard cycles.
Resale value trajectory
The WA380 has retained approximately 48–55% of original list price after four years of mixed-duty service in the NL/BE/DE market, roughly 5–8 percentage points below equivalent Cat 966M values. That reflects Komatsu's slightly lower brand premium in the wheel loader segment. The differential makes the WA380 attractive to value-oriented buyers, since the lower entry cost does not correspond to proportionally lower reliability or capability. Machines from the 2016–2020 production window with KOMTRAX-verified service histories trade at a clear premium over undocumented examples. After five years, values settle around 38–45% of list, with German aggregate plant machines at the higher end due to regulated maintenance schedules.
Alternatives in this class
The Caterpillar 966M is the premium alternative, commanding 10–15% higher acquisition prices but offering stronger residual values and the option of the 966M XE electric-drive variant for operators focused on fuel cost reduction. The Volvo L120H matches the WA380 on operator comfort and exceeds it on fuel economy through the OptiShift lock-up transmission, making it the preferred choice for port and waste management operators running long loaded-carry distances. For buyers seeking a smaller, more economical loader, the Komatsu WA320 offers a 15-tonne class alternative at 25–30% lower acquisition cost, though bucket capacity is significantly reduced.
