I know many of you guys have seen these videos and I understand that the last one was from zrau17:
The first one appears to be really complicated, and the last one looks to be easier to duplicate. Has any one else done one of these or has their own version of four wheel steering. As some of you already know from my previous posts, I run my MERV/Summit indoors only, with my two year old boy, and I could really use the four wheel steering. Please post pictures, links or ideas on how to obtain four wheel steering.
Thank You in advance
