My Hustler Super Z doesn't do a good job. The unit does not disperse the grass efficently, thus causing me to have to slow the machine down to a crawl. Also, I have wind rows when the grass is high. I am talking about between one and one half and two inches. I took a demo Exmark to this same location(about three forths of an acre) and it did an excellent job. It did a super job of mowing and dispersing the new cut along with the wind rows from the previous cut of my Hustler. It also took me almost twelve minutes less time to cut with the Exmark than the Hustler. My question is: Have any of you had this same problem and if so, how did you remedy it. Unfortunately, I think it is Hustler's deck design that will not allow for large quantities of grass. I will state that it does mow very well when the yards are properly maintained, but by being a small company, I need to mow fields and lawns to stay in business.
