Question #1: My mower has 3 blades and I can only cut on the highest and 2nd highest height? Question #2: My mower turns right like a zero turn but does not turns left like a zero turn and the right back chain slips off? I only bought this thing for $400. I'm pretty handy. So, if someone can give me a list of parts and instructions (or a manual), I think I can fix it. THANK YOU FOR YOUR FEEDBACK!!
