973K Track Loader

Save money and transport time with one rugged machine for land clearing, digging, grading, truck loading, slope work and more. Crawler loaders give you reduced ground pressure and better traction so you can start the job earlier and work longer in soft underfoot conditions. Purpose-built Waste Handler, Steel Mill and Low Ground Pressure configurations stand up to the toughest applications. This new generation of Cat® Track Loaders brings you all of this, plus improved performance and fuel efficiency.
