Certified Pre-Owned

Overview

A brand new way of looking at used…

If you’ve ever considered purchasing a used tractor, combine or self-propelled sprayer, this is the ideal time. Besides the impressive fuel economy, comfort, convenience and technology found in all John Deere machines, the value that comes with purchasing a John Deere Certified Pre-Owned (CPO) machine is hard to ignore.


Every Certified Pre-Owned Tractor, Combine and now Self-Propelled Sprayer is covered by a comprehensive PowerGard™ plan, giving you the coverage benefits of new with the extra value of pre-owned. Right now, no one else offers a low-hour machine that’s been field tested, inspected and certified on over 170 points for tractors and 200 points on combines and sprayers. Add to that a free one-year JDLink™ Connect subscription, and a John Deere Certified Pre-Owned machine deserves even more of your attention.
