Hi Im a first time forum user long time tractor user. I decided to desert my GREEN machines of the past and bought a Dixie Chopper this time. Model # XWK2501-60, Kawasaki FH721V engine. Ive had her two weeks, mowed about 20 acres and the throttle cable has broken twice already. Is this a common problem with this machine or what? Can anybody fill me in? Thanks!
