Yes it has the 3 cyl. motor. That's about what I figured it was worth. I am not familier with CH? Lowville is about 30 miles East of Lake Ontario in Lewis Co. Where is CH located? The idea that it would be simpler to swap with Landis for another one had crossed my mind. Most of my neighbors at the time had 420/430 JD crawlers. The JD's were okay, but not in the same league as the OC 4. No, Pop didn't run a compression or leak down test. The thing has sat long enough now that I would do a complete engine tear down anyway. The motor ran fine, didn't smoke much, just fouled the center plug every few hours. Other than the tranny not going into reverse, all the forward gears seemed tight and working fine.
