Just got a new 48" DD Ferris Fixed Deck on Friday. Used it a little yesterday, put a Proslide on it today and adjusted the deck. Worked fine after I put the proslide on it, used it to mow 1/2 my lawn. Then I adjusted the deck, where you have to move the 4 bolts on either side by the drive tires. Raised it up to 3 1/2" cut from 2 1/2", now I don't have any forward drive in my right hydro. The reverse works fine, but there's absolutely nothing forward. Brake is off, and there's pressure there if I jack the tire up and try turning it with my hand. Belt is on. It's not "freewheeling". Any suggestions?? Yes, it's under warranty, but I'm about 3 days behind right now and if I could fix it tonight myself, it'd save me the trip the opposite direction of where I'm actually mowing for the next 2-3 days. Thanks, Jeremy.
