We have a 2005 Super mini Z with less than 100 hours on it, that has been having problems with cutting out(even completely dying) when mowing. Mostly on ruff terrain but can be at anytime also. We've had it in the shop and added flex forks to help the bumping and then had some parts replaced on the carb. to try to remedy the situation. After the repairs, we mowed again and no change. Also, since the carb changes the mower seems to have lost some power. It now boggs down when going up an incline to the point of completely shutting off. It's also throwing out clumps of grass like you can't believe. I'm going to take pictures the next time so I can see if this is normal. We've spoken with the dealer and he indicates no one else is having any problems so there's not much else he can do for us. I don't believe this to be the case, since I've read a similar thread regarding mowers with the Kaw motors that have the same exact problem. He said he was going to have a Hustler rep contact us so they could come out to our mowing site to see the problems first hand but we have not heard from anyone. Not trying to ruffle any feathers but it's getting very frustrating. Everyone says Hustler has great customer service but all we seem to be getting is "it must be how your mowing". We've taken a Scag demo and a John Deere demo to the same locations and they mowed just fine. Never once did either of them cut out or bogg down. Anyway, sorry for the long post but we don't know what to do next. Please help.
