Top 10 Reasons why you should buy your next Used Machine from Patten:

  1. Save money. Used machines offer a cost-effective alternative to purchasing new Caterpillar® equipment.

  3. Save time. Our expert staff will search for used machines and complementary work tools for you so you can keep working on the jobs that matter most.
  4. Exceed specifications. Every machine is put through a multi-point inspection to determine functionality. You can rest assured that you are buying premium used equipment.
  5. Have your pick. Patten Cat offers a full line of Cat and non-Cat used machinery from small skid steer loaders and mini hydraulic excavators to large dozers, trucks, excavators, track loaders, wheel loaders, and more.

  8. Warranty options. While not every pre-owned machine comes with a warranty, we offer a full line of customizable warranty and maintenance plans to suit your needs.
  9. Plan for the future. Caterpillar used equipment holds resale value better than competitive used equipment.
  10. Be a second owner. Patten's full service shop maintains our vast fleet of rental machines to ensure quality, and one-owner machines are available for your used equipment needs.
