Core Specs & Performance of the Komatsu 250-6

Once you understand where the Komatsu WA250-6 fits in your loader lineup, the next step is looking at its core operating numbers.

Engine & Power

The WA250-6 is powered by a Komatsu SAA6D107E-1 (made by Cummins) engine producing roughly 140  horsepower.

That puts it in a range where it can handle steady production loading, snow clearing, and truck loading without stepping into heavier fuel consumption territory.

It’s built for consistent torque delivery rather than peak horsepower. So essentially, that means smooth power during repetitive loading cycles.

Operating Weight

Depending on configuration, the Komatsu WA250-6 typically weighs between 25,500 and 27,000 pounds.

Weight matters for two reasons:

  • Stability during lifting
  • Transport planning between job sites

It’s heavy enough to stay planted during material handling but still manageable for transport compared to larger production loaders.

Bucket Capacity

Standard bucket capacity generally falls between 2.5 and 4 cubic yards, depending on setup and material type.

This range makes it suitable for:

  • Aggregate
  • Sand and gravel
  • Snow
  • General site material
  • Manure

The bucket configuration you choose will directly affect lift performance and cycle efficiency.

Lift Capacity

Rated operating capacity typically falls in the 8,000 to 9,000 pound range, depending on configuration.

As with any loader, exact lift performance depends on:

  • Bucket size
  • Counterweight setup
  • Tire selection
  • Load centre

Always confirm the specific configuration you’re working with.

Dimensions & Transport Specifications

Beyond power and lift capacity, physical size matters just as much. The Komatsu WA250-6 sits in a range that balances stability with maneuverability.

Overall Length

Approximately 23 to 24 feet with bucket installed, depending on configuration.

This gives it enough reach for efficient truck loading while still being manageable on mid-size job sites.

Overall Width

Roughly 8 to 9 feet wide, depending on tire selection.

Width plays a major role in:

  • Transport planning
  • Access to tighter urban sites
  • Municipal street and snow operations

Always confirm tire configuration when planning transport.

Overall Height

Typically just over 10 feet to the top of the cab.

Height clearance becomes important for:

  • Shop access
  • Indoor storage
  • Low bridge considerations

Wheelbase

Approximately 9 to 10 feet.

Wheelbase impacts stability during lifting and overall ride smoothness during loading cycles.

Transport Considerations

At roughly 26,000 pounds operating weight, the WA250-6 is generally transportable without stepping into oversized production-class territory.

However, transport requirements will depend on:

  • Local provincial regulations in Western Canada
  • Trailer rating
  • Bucket removal during hauling
  • Tire configuration

Compared to larger loaders like a WA320 or WA380, the WA250-6 is easier to move between job sites while still delivering solid production capability.

Purchase Price, Fuel Efficiency & Operating Costs

How Much Does a Komatsu WA250-6 Cost?

The purchase price of a Komatsu WA250-6 depends heavily on year, hours, and condition.

Used WA250-6 (10,000–15,000 hours):

  • Typically $70,000 – $95,000 CAD

Older units with higher hours will fall toward the lower end. Well-maintained machines with service records command more.

Mid-hour units (5,000–9,000 hours):

  • Generally $95,000 – $130,000 CAD

Condition, attachments, and regional demand will influence price.

Low-hour or late-model WA250 units:

  • Often $130,000 – $180,000+ CAD

Market demand, emissions tier, and dealer inventory can push pricing higher.

Fuel Consumption

The WA250-6 is built for efficiency within the mid-size loader class it offers: 

High performance SAA6D107E-1 engine Electronic heavy duty common rail fuel injection system provides optimum combustion of fuel. This system also provides fast throttle response to match the machine’s powerful tractive effort and fast hydraulic response. Net: 103 kW 138 HP.

The high-torque engine and HST with maximum efficiency in the low-speed range provide low fuel consumption  

The efficiency of HST motors HST provides quick travel response and aggressive drive into the pile. The variable displacement system automatically adjusts to the tractive effort demand to provide maximum power and efficiency. When high drive torque is needed, both motors are engaged to provide highest torque. Maximum rim pull can provided from zero travel speed. This combination makes the loader very aggressive and quick at digging, climbing or initiating movement. When high travel speed is needed, clutch cuts off the low speed motor to eliminate drag and achieve excellent fuel efficiency.  

Fuel efficiency is one reason contractors choose the WA-250-6 for their operations. 

Maintenance & Service Costs

Operating costs extend beyond fuel.

Key cost factors include:

  • Routine maintenance (filters, fluids, scheduled service intervals)
  • Tire replacement
  • Hydraulic system wear
  • Brake and drivetrain components

As machines accumulate hours, maintenance planning becomes critical. Higher-hour units may come at a lower purchase price but carry increased service risk.

Total Cost of Ownership

When evaluating a WA250-6, most buyers should consider:

  • Purchase price
  • Financing costs
  • Insurance
  • Fuel consumption
  • Maintenance and parts
  • Downtime risk

A lower upfront price does not always equal lower long-term cost.

That’s why many contractors compare buying versus renting, depending on utilization rates and project timelines.
