There was not too many small dozers made--ones I can think of are Struck, Magna-Trac, and Cletrack, and the Oliver OC-3. That one looks like a Struck to me, but there might be others I never saw or heard of too--try a google image search of a Struck and see if it looks the same?
All the pictures I found of the Struck ones looked like you sat on them. This one is a bit bigger, you actually sit kinda in it. I couldn't get very good pictures since the shed was pretty small, but the hydraulic tank is actually the seat back.
Looking more, it may have started as a Beetle trail dozer. Does anyone have any pictures of the drive gear assembly to help with ID?
My dad had a Beetle dozer when I was a kid, but it looked very different- especially from the back. Aside from the tracks, I'm not seeing any similarity at all.
Ok, I stopped by again today to do some diag work on the drive, and took more pictures:
Doesn't look like a Struck of any flavor I've ever laid my eyes on. Agricat was another manufacturer of small crawlers. Looking at the pictures nothing sticks out of a particular manufacturer. Any chance the chassis was re-purposed and turned into a crawler? Maybe check Vermeer they made some oddball stuff over the years. I wish we weren't on opposite sides of the country. I'd love to check this beauty out!!!!
I would love to have a look at it too. I had one made from a Vermeer T200 trencher. The drive on it was separate hydraulic motors for each track.
From looking at JD Crawler's build thread, it seems the fuel tank is from a Wisconsin V4. I haven't found any crawlers that used this engine, just singles or inlines like the Continental fours.
Try looking up MEAD Speedcat. The undercarriages look pretty close to what you have pictured
I had looked at those and the Agricat, the track adjusters are very different. The blade pivot is in the right spot for the Clark CA-1, but the adjusters are different and the gearboxes are all wrong.
There probably is, up here we don't see many mini-dozers--in PA it seems to be the jackpot for all kinds of garden tractors & farm equipment...in MA we have quite a few old garden tractors still kicking around, but anything larger the few that could afford to buy them never seem to sell them--a lot of them sit in the weeds on an old farm abandoned, until they are scrap, and get hauled off for junk, before someone willing to restore them hears about them. I have seen a Mead Speedcat that was for sale at a small engine show--no engine or pump, and it looked like it sat outside a long time, 500 bucks or B/0...it did look similar to the one pictured here...
The odd identifying things on this dozer seem to be the gearbox, outboard bearing on the drive sprocket, and blade arm pivot location. It has an input shaft, small differential with what looks to be ball clutches driving sprockets, with a chain drive to a gear reducer driving the sprocket. The reducer is a single pinion running on the outside of a ring gear that is on a common shaft with the sprocket, so the chains actually run opposite the direction of travel. The pivots are quite far forward as well.
