What about using a common KB Electronics DC drive?
Woot.com (Amazon discount site) is selling one for $89. I think they
can commonly be found on Ebay as well.

Way back in 2003 I started a project to control the surplus tread

The first prototype had a bunch of problems and then regular paying
work took over, I needed the bench space and never revived the project.

The controller was the MC33030
