it can take a decade or more to bridge the gap between seeing something, and learning what it is... there are just SO MANY things to learn in this world, even in the small segment of the world that is tractor focused, but I finally got another, the Fordson with a Rotapet 4 chain drive adapter with caterpillar like tracks

about 10 years ago (serious, the really good days of blogging, when the content was SO FOCUSED on machinery, and barely any news) I came across a similar Fordson with a track conversion that looks a lot like the above, but it had 3 spades per flat  https://justacarguy.blogspot.com/2016/04/this-british-built-square-tracked.html

and the year before that, Martin (super cool incredible artist) posted https://justacarguy.blogspot.com/2015/08/martin-squires-auto-blogger-illustrator.html

So, I'm not saying these are all Rotapet, but the first one is on the blue Fordson, and you can compare for yourself the other two.

I simply amazed that in just 4 days, I've came across this decade gapper of a tractor track drive, and the OTHER tractor with the incredible flip over traction front rims, the Pavesi https://justacarguy.blogspot.com/2025/05/andre-knew-about-these-military-wheels.html
