I bought 3 exmark 30 inch lawn mowers this spring. I was one of the test dummies. We had some problems with the transmissions on all three mowers. We had some cables breaking. It was frusturating early on. The transmission problems seemed to be worked out. The cable situation is taken care of by exmark redesigning the ball in the cable. I really like the exmark 30's. Yes there has been some adjustments that needed to be made, but I knew that would happen in the early stages. People on this site are asking if they should buy a 30 inch exmark. I would say yes if it applies to your situation. I love the cut, changing from discharge to mulch to bagging is simple. I really like Kawi engines. We save gas and you can run them a long time before you need a fill up. They are fast and much more productive then 21's. Easy for employee's to pick up. The self propel is easy on the hands. They are easy to turn. The ht adjustment is easy and it goes up to 5 inches. I love the timed blades. Maint. on the machine is easy. I haven't seen any turf tear or rutting. There are limitations on this machine as there are on any mower. They are not good on hills, if you have to cut super high grass this may not be the best machine. I really like the support I got from Exmark. I called and talked to them and they gave me honest feedback. They told me early that they had a tranny problem and they would correct it. They then added another year of warrantity for the trannys. They came out and said they needed to fix the cables and did. In a time when many business's don't live up to backing there product it was nice to talk with exmark's manager Paul Jurgens. Paul really helped me out and not with just talk but action. Every business encounters adversity, what that buisness does in those times separates them from the pack. This why I bought three 30's from exmark and will continue to buy exmark: It's a really good mower with really good support behind it. Just my honest opinion for other landscapers interested in this mower.
