Haas Tractor Club Update

Model D Production

As the founder and coordinator of the Haas Tractor Club, I wrote an article (see GEM, December 2000, page 20) about our first reunion at the Baraboo, Wisc, Badger Steam and Gas Engine Club Show. We were happy to see the article printed and want to share our sincere appreciation for that. I doubt we often realize the impact such articles can have on others. The direct result of that article was two new members and friends for the club, neither of whom had an inkling such a club existed. One person had never heard of Haas, while the other had a Model D and was searching for information about the tractor and its history, as well as restoration assistance. The Model D came complete with its original bill of sale, which gave us new dates and figures to work with that had not previously been available. That tractor also gave us another look at original paint colors.

We have been able to pinpoint early production of the Model D as mid-1949. This series started with serial numbers after 1000 and up. A later variation started at 2000, however all numbers are quite low regardless of category. We know only 300 Model Ds were produced, and most were exported. Some have been seen in Germany, and pictures of some in China are known. The Model D used a common 140-cubic-inch Continental engine and a B.F. Avery transmission made by Clark, while the Model A and the Model B used a Haas-made engine with Ford Model A car parts where they could. The A and B were similar except for an extra two-speed gearbox in the Model B.

Considering how few Haas tractors were made, it's amazing to see this many in one place. The larger tractors to the right are Model D Haas tractors, while the smaller units to the left are Model A Haas tractors.

The Model A tractors have not shown up and the Model B tractors are hard to find, usually requiring a great deal of restoration. Both the D and B were made in Racine, Wisc, and many of the Model Ds are in Wisconsin. It seems, however, that most of the Model B tractors ended up in Michigan where some were used as factory mules in the Continental engine plant. I have given up finding manuals for either tractor.

I plan to complete a restoration handbook by show time for the Model D. This will include parts drawings as well as tips on making needed repairs and parts sources. Our second reunion was again held in conjunction with the Baraboo show in August of 2001. We voted at the time to come back in 2002 for our third reunion. This year's show will be held Aug. 16-18. You can find more information on the show at

We encourage members to let the club know if they plan to go to any other shows so we can have additional meetings in other places, as well. Thanks again to GEM for helping us get started.
