Holla!
Yeh, there was one John Deere we had that had 300bhp and rear wheels over 6 foot in diameter, good fun for terrorising othe road users!

We also used to take the weights off the front of the tractors, stick a heavy pallet on the back and see how far we could wheelie steering with the rear breaks.

Not quite in the same league
but I used to drive a Fordson Super Dexter that had independent brakes. Excellent for cornering in the mud.

Very true.
I have never driven a Fordson, we did have a 1968 Ford 4110 that was quite a giggle.
