We've used this tractor heavily for front end loader work weekly for 37 years. It has always been strong and very reliable. Often with poor maintenance. It has also cut, raked, and baled thousands of tons of hay. I use it commercially with a 6' brush-hog mower.
The engine is tired now, and the Dunham loader is almost worn out, but it's still used regularly. The only negative is the 3pt hydraulics sometimes stick. A good old friend.
