Oh my mistake Jim sorry i had winch on my mind for added weight for traction, wow thats alot of bevel on the drive sprockets!! as for track tension is there room to add a set screw to look front idler from moving back an loosening tracks? you would have to adjust it once in a while, our old ac had a huge wrench to turn a thread that put more tension on and my case uses a piston afew shoots of grease from a grease gun and shes tight, but i really believe your limited for space ill keep thinking tho, im assuming your hoping for automatic adjustment?
