Wow, congrats on moving the project from vapor to steel so fast! That is gonna be one cool ride when you are done. Love the dual rear shocks. Have you given any thought to possibly angling the bottom of the battery box at the front from the sides and the bottom? Two inches of 45 degrees (or possibly 3 or 4 inch radius at the front) just to give the box a chance to jump over a root or an ankle a chance to glance off the front edge of the battery box? I caught the front edge of my mower deck on a root and would up out in front of the tractor at about 10 mph and it was very abrupt
Not to mention having to roll out from in front of the running tractor and mower. Seems the only safety equiptment on an early 6N Ford tractor is between the operators ears(fail).
