I needed a bigger machine so I sold my JD210 and bought the 322. It was a 1991 Indiana State Fair "demonstrator" so I am the first and only owner. I chose it over the 332 because I was more familiar with gasoline engines at that time.
I have not been disappointed in any way... other than they don't make tough tiny tractors like it any more. This machine works year round: Mowing, plowing, some ground engaging work, pulling deadfall, clearing brush, etc. It has never failed to start.
I do all the maintenance on it. So far, other than fluids, filters, lubricants, it's needed 3 sets of spark plugs, a voltage regulator, a fan belt, 2 fuel tank caps, front tires (back ones soon), a seat cover replacement, and a dab of paint here and there. It's an amazing little tractor.
