I've posted on this forum several times about issues that I've had with my new Super Z mower, hoping to get feedback from the pro's on here. I want to thank each and everyone of you that has replied. I also wanted to take a moment to let everyone know how these issues have been handled by Hustler, and their representatives. I drove a long way to purchase this mower, to a dealership that was recommended by a fellow member here on Lawnsite. This Dealership is in Oakwood Georgia, called Georgia power sports, owned by James Allison. James, and his partner Gerald own one of the largest Hustler dealerships in the United States, and after dealing with these two gentlemen it's easy to see why. They take the approach that if your not happy then their not happy. The mower that I bought was a left over model built in December of 2005. This being a left over 2005 model it had a lot better price than a 2007 model, but still had the same warranty, thus the reason for me driving that distance. The model didn't really matter to me as much as the warranty did. The fact that this mower set around out in the weather for over a year without being run is probably the reason for most of the problems that I've had. I also want to note that a Hustler rep lives about a mile up the road from me His name is Ken Frye. Ken has bent over backwards to help me on these issues. He has came to my house, loaded up my mower, and took it 45 miles to the Hustler dealership in Murfreesboro TN twice to have it checked out. I can tell by talking to him that He truly believes that Hustler is the best mower out there. I still have a few issues with the mower, but I am totally confident that Hustler will in the end make me happy. I know this sounds like I'm trying to sing Hustlers praise, but I can't help it. I'm the type of person that just tells it like it is, and if you treat me right I'll tell everyone, and if you treat me wrong I'll still tell everyone....lol Issues that Ive encountered, and fixes: -Starting problem (fixed): Starter replaced mower has started every time since replacement. -Sputtering problem (fixed): Seems that the fuel lines were floating up in the tanks. Stainless weights were attached to ends of lines. this seems to have helped solve problem. -Chattering when sticks full forward : We may have actually found the solution to this problem today. I talked to Gerald at Georgia power sports this morning about the problem. He said that they had a similar problem with a mower just yesterday. They replaced the tension spring on the idler pully, and it fixed the problem. I got under my mower, and noticed that the spring didn't look like it was stretched out very much. I decided to try to increase the tension on the belt by looping tie straps in the coils of the springs, and drawing the coils together. Guess what, I took it out shoved the sticks all the way forward, and the chatter that I was experiencing was almost totally gone. I'm not totally sure this is a spring problem though. The belt itself may be stretched, because the idler pully already looked like it was almost touching the deck belt, and I don't think that it would be designed to run so close to each other. Who knows it could be the spring, and the belt both causing the problem, but the solution now seems close at hand. -Power loss on hills : This is the one issue that no one can seem to agree on. I've read numerous posts on here with different views on this subject. Some say that this is just a Super Z issue that you get with the bigger pumps. Some say that their Super Z mowers will gain speed up hill, and that the blades will gradually come back up to speed. If I'm even on a slight upward grade trying to come up to full speed, my RPMs will drop considerably, and unless I back off on the sticks the RPMs will never come back up all the way. On the steeper grades I'm not talking sticks all the way forward, I'm Just gradually trying to gain speed up hill as I go, but as speed increases the RPMs will just go down. I guess the best test would be for me to get another Super Z on my property to see if I get the same results. I may contact my neighbor to see if He can bring another Super Z up just to see if they run the same.
