  1. Sargent plow. They were designed so the tractor actually pulled the plow rather than pushing it.
  2. Very good price with a lot of parts support and an active community.
  3. Fantastic work Roger! Regardless of the title I always have to check and see how this amazing project is coming along. True craftsmanship! Thank you for sharing!
  4. Little bit of but important clarification: The 1909-1910 Mercers used the Beaver built engines. Later Mercers 1911 versions used a Findley Robertson-Porter T-head. Yes, I wonder too who else bought these engines! I have found Beaver advertising through 1924 so they must of had a decent customer base. I suspect that most manufacturers that bought engines from outside suppliers tried to minimize that fact to maintain the impression that everything was made in-house. I find the same thing with Wisconsin engines as well. We know Stutz used them but outside of that not much is know in regards to who they supplied.
  5. No connection with Wisconsin Motor Manufacturing. Beaver was based in Milwaukee with the parent company listed as Filer & Stowell Co. They appear to have maintained a pretty good level of advertising visibility in period publications. Their advertising targeted manufacturers of cars, trucks and tractors. This was a screen shot taken with my I-Pad so please excuse the un-cropped areas. I am pretty confident this engine powered the Mercer featured in the original post. T-Head, six cylinder, proper time frame and by Beaver of which Mercer used almost exclusively until the advent of the Delling designed L-Head. This was clipped from “The Automobile Trade Journal” (February 1913). Note the reference to 1913 being the “…sixth successful year building six-cylinder motors”
  6. Mercer sourced engines from Beaver though one source claims that Finley Robertson Porter tuned them if you will. However I cannot find any primary source material that supports that. The outlier are the race cars built I believe in 1908 under the Roebling-Planche name that used a beast of an engine that may have been designed by Etienne Planche but no one knows for sure. Remember also that Finley Robertson Porter seemed to have an affinity for large four cylinder engines as witnessed by his development of the big thumping four cylinder, overhead cam FRP and his swan song Porter automobile which used the FRP engine as well. As far as I know, until the introduction of the later L-head, the T-heads used by Mercer were traditional T-heads with no separate head. Since Mercer, like many other manufacturers, purchased their engines from various suppliers, they seem to have tended to keep that knowledge hush hush to a certain degree. For instance there are a number of period articles on the various Mercers which dive into great detail on the engines but seldom mention that they were supplied by an outside source. the later Mercer L-Head was designed in-house by Eric H. Delling who later designed and attempted to bring to market a fascinating steam automobile. Do a Google Books search for Mercer automobile, Beaver engines etc. Pretty cool period articles crop up. It can quickly turn into a very deep rabbit hole!
  7. I was always understood that Mercer purchased motors from Beaver Manufacturing while Stutz did in fact use Wisconsin T-Heads. All of Wisconsin’s 6 cylinder motors were large, low rpm (1200-1400) beasts designed for marine, truck, tractor or industrial use.
  8. Back on February 17th we had our winter event at the museum. This got me thinking about a set of skis for the 10 ton Lombard Tractor-Truck. These machines were designed for winter use with skis for steering, however the factory also offered a kit that allowed wheels to be swapped for the skis. This particular machine was purchased new by the city of Waterville, Maine in 1934 and used for plowing and either lost the skis at some point or never had a set. anyway, with the Tuesday crews help we have logs on the way to the mill and will shortly have 5x8 Timbers to cut out the skis from. Being a logging museum with a fully functional mill complex and having plenty of salvage logs after a recent winter storm makes this aspect of the project that much easier. Today, Paul removed the pedestals, stock and axle from another Lombard that is in the restoration queue. now we just need to gather it all together and purchase the steel and fasteners. Update: 3-5-2024 It being a beautiful day at the Museum, with the infamous Tuesday Crew out and about working on various project, Charlie, Aaron and Byron ran the logs through our vintage Hackett & Witham sawmill. so we now have some lovely 5”x8” Timbers to work with.
  9. Of more recent vintage, the short lived but clever Costin Amigo comes to mind which used a wood chassis.
  10. I believe the Reading steam carriage used a similar setup with upright cylinders attached to a fire tube boiler.
