I Know a lot of you have seen my posts on here concerning the purchase of a Kubota ZD-28 Verses a Hustler Super Z, and I greatly appreciate all the help that I've received. I have had a demo on the Hustler, and Thursday I'm going to my friends house to demo his Kubota ZD-28. I asked him today if he has had any warranty issues with the mower since He's had it. He told me that a hydraulic fitting had to be replaced about two weeks after he got it due to a leak, and that one of the blade spindle's had also been replaced. The dealer told him that he had over tightened the blade to cause the spindle problem. He didn't believe this to be the case, because he doesn't use impact guns, He uses hand wrenches. Who knows , maybe He's stronger than He thinks... lol. I would like to ask the ZD-28 owners on here, How many hours of operation do you have on your machine, and what type problems if any have you encountered with your ZD-28? I would also like to know if you feel like the 28hp diesel is adequate for the 72" pro deck? I'm a home owner that will probably put around 100 hours a year on the mower, and I'm looking at spending around $8000, so this is a very big one time investment for me. Is the number of grease fittings a big hassle on the ZD-28? I realize that I ask a lot of questions, but this is the only way to learn. I also realize that the opinion of someone not trying to sell me a mower means a great deal. Thats why I appreciate this web sight, and the great informative forums here.
