I cut for the first time today, onions (wild garlic) and Henbit is really bad. I walked out and checked the oil in the 28 efi, got on the mower, turn the switch, it turned over twice and was purring like a kitten. I set the deck to cut at 2 1/2" and was cutting onions at 15 mph and not leaving a sprig standing. The Hustler Super Z never ceases to amaze me how it will cut at 15 mph and do an excellent job in my situation. When you mow onions and get a clean cut at 8 mph is one thing but when you can do it at 15 mph is really unbelievable. These are fusion blades that were sharpened 8 hrs. back so they are not new dead perfect blades by any stretch of the imagination, I cut through a tremendous number of fire ant mounds. I have cut many, many acres with this mower and it still blows my mind every time I mow and see how much area I can cover in such a short period of time. Cutting low is what makes the difference, if I attempted to cut those same onions at 3 1/4" or above I would have to cut the speed in half and would still see a straggler all along. It is really a joy to get on a mower that cranks, runs and cuts that well, especially with that speed.
