Since 1976 Portland Tractor Inc. has been a leading supplier of rebuilt and used heavy machinery parts, components and attachments, specializing in Caterpillar® parts. Over the last 40 years we've built our reputation by working hard and being honest with our customers. To us, honesty means being up front with what we can do, what we can't do, then standing behind the quality of our product. Sticking to these principles has allowed Portland Tractor to build the relationships that have become the cornerstone of our company today. Thanks for visiting our website; feel free to contact us if you have any questions, or if we can help you in any way. We look forward to working with you.
