I had a heck of a thought last year in the tractor while haybining, what if I could somehow run a hydraulic pump from the gear box to the front wheel so that I could have an all wheel drive motorized bike? This would be awesome for the kind of terrain that I live on. I don't think anything like it exists but if it does I would love to know about it. If not any ideas on how I could do this? I understand all of the complications involved in this like the motor would have to be huge and finding the parts would be downright impossible. Any imput is appreciated, thanks.
