Looking for some 12” track pads for a TEN . Others will work with some modification . The twenty two seems to be the same pad just a different bolt pattern . I am in the western U.S . Thanks
F.p. Smith equipment in Fairfield california. I was here a few years ago. I saw some machines with narrow pads. I didn't have interest in these machines at the time, so I don't know the details. They possibly were earlier D4. But maybe give them a call. They are good folks to deal with.
I assume "Piggy" Smith passed on years ago. About 30 years ago I bought some grouser bar for D4. Pete up sold me the tall ones. It worked out well and they look good but it sure tears up the yard going through.
