I have about a year old 42 inch Sport with the Kawasaki engine. I love the thing. I've been having an issue the past couple of times out. On flat dry grass, if I go in reverse the rear right wheel spins. I checked the tire pressure and they all seem fine. Also, and I am not sure if this is related or not, but I was going down a slope and tried turning left (so right steering bar pushed forward) and it would not turn. It's as if something is off with the right side steering. ANy advice is appreciated.
