Two tractors that were fine, playing and being built / developed within the rules, numerous issues, lots of time and development $, and when they finally get running good.. rule change. I've been around pulls for over 20 years, and this is not the first time that ECP has done something like this. Then they act like they did nothing wrong. They could have dropped weight or lowered the hitch, but instead just outlaw them. You really can't blame them to much for being scared.
