I was taking my equipment up to my dealer for some pre season work. They said that Exmark is doing warranty work on just about all the HP models. Something with the exaust system that they have to change. They said it takes 1.5 hours for each laser. THere was 95 ahead of me, so I just thought those of you who have HP's would want to call your dealers and ask them about it. They don't even have the parts in yet!! I hope my stuff is done in time!! Looks like they are going to be up there for awhile.
