973K Track Loaders

Save money and transport time with one machine for land clearing, digging, grading, truck loading, slope work and more. With track loaders you get lower ground pressure and better traction so you can start earlier and work longer in soft underfoot conditions. Cat® Track Loaders bring you all of this, plus improved performance and fuel efficiency.
