Scag Tiger Cat or Hustler X-one, $8,500 for 60" mowers. Don't know what the 52" cost but Diesel is way out of your price range.
If you've really priced out new machines you would know that a diesel is out of price. Unless you were going used which may be why all of your machines engines blew up. Because they weren't cared for by the previous owner.
There is an Old Blue Chair for each and every one of us, we just have to find it.
