Collecting antique tractors provides a physical link to our past - a glimpse of what our early landowners used to shape the countryside. I collect Massey Harris since those were the tractors my family used. My MH Pacer is a great tractor that was used for smaller jobs. The National Massey Collectors Association (MCA) is a chartered organization consolidating all interested parties in Wallis, Massey-Harris, Massey Fergusonand Ferguson tractors, related equipment and memorabilia.
