. They are supposed to be going to test a new 38 HP diesel with a much lighter engine than the cat. He said estimates were 100 pounds heavier and we may see them as early as spring. Called around to several dealers today who sold Hustlers and other mowers. One dealer sold Grasshopper, John Deere and Hustler the other sold Exmark ,scag, Ferris and Hustler both dealers told me as of 2006 the Hustler were the hottest thing going they had and that practically all the people who were using the Hustler products could not believe how much faster and smoother riding they were over their other riders. That was just 2 opinions but if they get the power thing sorted out with a light weight diesel I am in for a 72 come spring! I started a new contract this week and I was amazed at how fast my super got the job done and the way the empolyees could ride at 12 or 13 MPH with no major complaints about the ride being brutal. With the solid front tires on my Exmark ZTR you cannot cut near as fast. So far I am very happy , best ZTR so far I ever owned by far!
