"I have had a lot of different tractors and the Jacobson machines are very heavy duty machines tube frame and very good transmission. I have the Supper Chief 1200 that has a 12 HP Kohler. The newer machines are not as good after 1980 but the 1960's to late 70's are the one to get! The front axial will get lose at the pivot point but a bushing can be made for it to tighten it up. This machine has a snowblower on it that is still throwing snow as of last years show storms!"
