I have a late '90's model Wheel Horse (bought new) and it has been a great little garden tractor. Primarily mow with it but have a snow blade and rototiller I bought with it.
Only problems with it have been related to the location of the battery. It is under the hood and right behind the dash so the electrical connections require lots of maintenance. I have to replace the fuse panel due to the fuses corroding, getting hot, and melting the plastic. After I became aware of it I now stay ahead of the issue. Great and rugged little tractor.
