I had another farmer loading and spreading chicken litter on my fields today. He has a farm with four chicken houses and a great deal of grass to mow. I was mowing in some big areas with the Hustler Super Z as fast as it would run. I rode up to talk with him a minute and he got off the Bobcat loader and walked up to me and said, " I wanted to see what in the devil you were mowing with, I've never seen anything cut grass that fast in my life, my brother and I were watching and saying there is no way that thing can be cutting the grass moving that fast". He then said "I use a Scag Turf Tiger and that thing makes it look like I am tied to a stump, you can't be getting a good cut, I don't believe the blades can keep up". I said stand on the edge of the deck and hold on, we will see if you think it can cut grass that fast". I took him over to where I was cutting and there was absolutely nothing left anywhere but cut grass. I had just changed the blades before I started and it was getting everything at 15 mph. There was no grass left to cut but I told him to get on the mower and turn it loose on a 500' straight run where I had mowed. He took off slowly and got a little feel then opened her up, he made his run and got back to where I was standing and said "that is unbelievable, if my Scag would run that fast I could not stay in the seat to use the speed". He then said "I believe your mower would cut my mowing time 30% or more and I still can't believe it cut the grass that good running that fast". I told him the newly sharpened blades were doing a very good job but the height I was mowing at really made the difference, then I said "if I was mowing taller grass at 3 1/2" I would have to slow down a great deal to get a half way decent cut". This mower is very productive at lower cutting heights and fast speed.
