I have an old FMC 5' rotary mower. Overall I am very pleased with it. What I don't like is when you mow in reverse the angle of the tail wheel raises the mower up higher than I like. I think most mowers are designed for the swivel action to raise the back of the mower but in my opinion it raises mine to the extreme. I don't think anything is bent. I'm thinking of changing the angle of the wheel to allow less lift on the rear when the wheel reverses. Anybody else out there ever have this problem?
