I started a thread awhile back about our local dealer not carrying Hustler anymore and I found out why the other day. He had said to me that there were 3 or 4 Hustler super Z's that had the same problems, the engine had quite for some reason and they were unable to stop the machine. One went into a busy street causing 4k in damage to a car, 2 went into ponds and 1 went into a bay off of our lake. I guess you have to engage the E Brake by moving the controls outward or something like that. But he said there was absolutely NO factory response on these matters. And there were a few other issues about the factory rep not showing up since 2004 and many stress cracks in certain spots that were occuring to several mowers. Thats too bad I was really interested in purchasing a Super or Mini Z this year. He sold (8) eight to a lawn care company last year and now he has lost that guy's business and he will never have Hustler again.
