Sorry wyatt I informed our webmaster, the competition has changed a lot, but the tractors now can't weigh over 850 lbs. w/o the driver
Its definately different w/ 4wd, I pull a cub as a hobby with the Mid American Pulling Association here in central Iowa and I had to start from scratch when I got on the 4wd
for all of you thinking about a 4wd cub, it definately takes a lot of time and resources to put together a good 4wd tractor (of course school keeps getting in the way)
yes the engine dyno worked, I spent a few months last year tuning an exhaust for our flowmaster exhaust system (they supplied the collector and muffler), but then the electronics fried so they started over this year and we hope to have it up and running soon
the fun toy now is the transmission dyno, but thats a whole different story
anyway I guess I have gone off on a tangent long enough
If I were to build on of these for myself, and I might have to since I am gaining plenty of experince and I have a few cubs to spare, I would most likely just make something similar to the tractor shown in the photo earlier just using cub hydrostat rearends, a diff lock would be great too, they pull so much better with the diffs locked, but they don't turn.......... at all, so I guess its all a trade off
