I am throwing this out there to see what can be done better.
Presently, due to the 80" wheelbase, F600's are driven via chain either straight back from the PTO to the axle or forward from the PTO to a jackshaft then back to the axle.
What about inventing/fabricating a third choice? This will be a tough one for the obvious reasons as you see the challenge:
Three gears straight back from the PTO -
1st one is the PTO gear itself
Middle is a gear to correct direction of rotation
Rear is the axle gear.
The challenge - how to hold it in place as the axle moves up/down and at an angle as one tire gets higher than the other AND do this at a rock bottom price.
I suspect that the FSAE teams have already come up with the solution at some time in their competition history.
If an elegant and cost effective solution can be had then the whole F600 class will be transformed.
Let the brainstorming begin!
