Thanks for the heads up.You could have one if you wanted.
Few if any compact tractors come with an air ride seat. But every single commercial or Ag tractor has that option because it's important to them.
For compacts and utility tractors it's a "find it yourself" aftermarket item. Grammer is the best known supplier of aftermarket air ride seats and can usually come up with a bolt-on kit for any tractor. They are the best, but don't advertise much.
An air ride seat will have a tiny 12 volt compressor and air shocks under the seat. Not too expensive or too cheap - about the same as a set of turf tires - and worth every penny of the cost if you have a bad back or just want to preserve a good one.
It's worth a phone call to Grammer. You won't believe how nice they are until you try one.
