The Cabelas tractors are made by TYM, at least for the most part. Search "Cabelas" or "TYM" here for a ton more info.
Overall tractor quality/reliability should be the same as the TYMs as they are the same tractors. Hopefully someone can come by with details on how good Cabelas handles warranty issues/etc. and if you can take it to a TYM dealer direct or not.
