938
Cat® wheel loaders set the standard for productivity, fuel efficiency, operator comfort and low operating costs. The Cat 938 Small Wheel Loader features a high torque C7.1 engine that works in conjunction with an intelligent hydrostatic power train to deliver exceptional fuel efficiency. Meets U.S. EPA Tier 4 Final and EU Stage V emission standards, designed to manage itself so you can concentrate on your work. Extended service intervals to 1000 hours reduce fluid and filter use by up to 45% (compared to previous M Series models) while keeping operating cost low.
