I was just told by my Hustler dealer that he was invited to a Bobcat mower company meeting a couple of days ago and they presented him with a plaque for selling the most Bobcats of any dealer in the US, $3,000,000.00 plus. Now to put this in perspective, Bobcat is his second best seller with Hustler being number one. He said the oldest Hustler he had in stock was around three weeks old. That means he sold all his inventory with no carryover in the worst drought ever recorded in this area, he must be a magician. He told me he drove a prototype Bobcat Predator Pro with a 37 hp. Kawasaki and 21 cc pumps that would cut grass at 16 mph. This machine is not even being talked about at this time. I told him I certainly would like to run one to compare with the Super Z. He said all this speed is coming about, but somewhere there had to be a speed you could not cut grass. I told him you could not cut at those speeds now; with 3 1/2" cutting heights and above, there is not enough suction to keep the grass standing up well enough to get a good cut. I have no problem at 15 mph with the lower cutting heights I use, but by the deck being closer to the ground you create more suction to hold the grass up.
