How does the Cheetah ride? How does it cut at high speeds? I have the Tiger cat and pleased, but I would love a little smoother ride and faster mower in time. I mowed two properties owned by the same owner today side by side totaling 10 acres of wide open field....10mph with a 52'' deck seemed like I was crawling. Plus the imperfections or ruts threw me around a bit. Does the 8psi in the front tires do well or feel great?
