DIY Home built compact tractor

AAUGH - I'm at the end. I just found this thread and read through it. I could feel my heart speeding up as I got into the April posts - hoping that the thing would be running before I got to the end of the thread. No such luck....where are those wheels??!!

I'm just dying to see what happens next.

Sorry guys, I'm still waiting for the wheels, loosing faith fast.
Latest "story" is another week, yeah right
But I've been getting a lot of other projects done in the mean time!

I see this as potentially the fastest 4x4 tractor on earth. Lacking a transfer case he is so limited to gear ratios.
Myself I would have stuck with the sammi tranny and divorced transfer case set up. I even would have went as far as putting two transfer cases in line to get tractor like gearing.
I admire what he is doing. and his fabrication skills are good.. especially for an engineer. LOL

GT2 please come back, some progress pics please!

Ericjeeper, the output of both VW tranny halfshafts are, off course, at normal VW car output speed. When putting this into a Sammy axle with 3.72 or whatever reduction, his total reduction ratio would be even bigger than a Sammy transfer case does... with the bigger wheels, he'd end up with ground speeds as fast as a standard Sammy with standard wheels, i suppose.
Still a bit fast for a tractor, but with the VW diesel i bet its going to be tons better than the 1.0 or 1.3 gutless gas engine.

You are correct it will be Sammi speeds. Except the 30 inch wheel factor.. Basically my point is it won't pull a sick ***** out of bed.
My jeep has a final crawl ratio of 120-1 or pretty close to that. And I am far higher than a lot of rock crawlers.

Hmmm you're right, i forgot that the VW tranny doesnt have a low gearing, and if the extra reduction in the sammy axles only make up for the bigger wheels, he'd still have the total ground speed of a standard street car, which is quite higher than a Sammy in low range 1st....
