I went to the local Hustler dealership today to buy a gas Super Z 72" and found they have several diesel super Z's that have all been "refurbished" from the factory, all with less than 100 hrs. on them. Salesman said that there were several "small" problems with these mowers that Hustler had fixed. Was there a recall on any part of the diesel super Z's ? Have you heard of anything like this? I am very interested in the diesel mower but suspicious of this story.
