G'day Gary,, it's good to see they have the problem sorted for you, fixed and all under warranty, as it should be. Maybe extended warranty might be the way to go,, I'm not sure if I have that or not on mine, I think I do, but I'd best check.
Theres plenty of these machines doing hard work in the scrub, so I personally don't think it's "just an urban warrior",, that would make it just a " soft roader ",,, I think not.
