Some friends used to have a big cookout every fall and they happened to have a big sandpit on the property with a good sized flat oval the kids would rip up with the atv's. Well the 'theme' of the day was some very informal run-what-ya-brung 'tractor' racing.
Not many rules, had to look somewhat like a lawn/garden tractor, I think a size limit of 4'x5' wheelbase. Some crazy stuff showed up, guys upped the game every year, got pretty wild.
That JD had an 1100cc bike engine, was definitely a handful...
My entry started as an old kawi 440 sled with some wheelhorse bits added here and there. Don't even know what top speed was, didn't have the nerve to try it, lol. Track was fairly soft and understeer/holding the corners was my biggest issue, tried all sorts of various front tire combo's. Was a straight rear axel so that didn't help, was going to try a differential of some sort but eventually the races stopped happening and I never got that far.
Years later the thing is still sitting covered in the back yard, I pull it out and pull it over once in a while and check that it's not becoming too much of a mouse hotel...
Concept; donor sled behind...
