Construction Equipment Guide

Komatsu America Corp.’s WA50-6 compact wheel loader is designed to bring increased production and added operator comfort to contractors in a variety of construction, landscaping, nursery and other applications.

The WA50-6 has an operating weight of 8,100 lbs. (3,674 kg), and features a maximum dump height of 8 ft. 1 in. (2.4 m). The standard auxiliary hydraulics simplify hydraulic, attachment installation enhancing the capability and versatility of the machine, according to the manufacturer.

The automatic electronic bucket leveling is controlled by the bucket control lever and increases the productivity of the compact wheel loader.

The WA50-6 is equipped with KOMTRAX technology, which sends machine operating information to a secure Web site utilizing wireless technology. Data such as operating hours, machine location and machine utilization are relayed to the web application for analysis. The KOMTRAX fleet monitoring system increases machine availability, reduces the risk of machine theft and provides other information to drive business efficiency.

Operator Comfort

For operator comfort, the WA50-6 allows easy entry and egress due to the wide entrance and well placed handholds. A fully adjustable suspension seat with retractable seatbelt lessens fatigue, and an optional cab with air conditioner provides a comfortable operator station throughout the year.


The WA50-6 features three working modes, which enables the operator to choose the mode that best fits his application:

  • P mode provides maximum rimpull for grading and excavating applications.
  • N mode is appropriate for normal/moderate loading or load and carry applications.
  • S mode virtually eliminates wheel slip allowing the machine to perform well in mud, snow, and other soft or slick applications.


The WA50-6 gets its power from a Komatsu engine with a net power of 38.6 hp (28.7 kW). The direct injection engine meets EPA emissions requirements and is fuel efficient. The “Delta Boom” loader design improves visibility to the work equipment, and the long wheelbase of 6 ft. 3 in. (1.9 m) improves ride quality and stability, according to the manufacturer.

Center hinge tapered roller bearings feature 1,000 hour lubrication intervals. The wrap around counterweight protects the main body of the WA50-6 and the rear combination lamps and exhaust pipe are built into the counterweight for added protection.

Service and Maintenance

To simplify maintenance, Komatsu equipped the WA50-6 with numerous features. The wide opening engine cover provides access to daily checkpoints. The filters are remote mounted and arranged collectively for easy inspection and replacement. In addition, the radiator and oil cooler are side by side making them easy to inspect and clean, and it ensures that only the freshest air reaches each component. Extended greasing and service intervals make it easier to schedule maintenance.
