I was hoping to make it until the end of the season with my 36" Exmark Metro. It has alot of hours on it and I think the motor is on its last leg (losing power, running like crap, smoking, etc.) I am wondering if I should put a new Kawasaki on it or just buy another mower. Nothing else that I know of is wrong with the rest of the machine. I got it used a few years ago so i don't know its maintainence schedule. It has been used very little by me until this year when I traded my new scag wb in and bought a Lazer Z. Now I have been using it on a lot of hills, etc. Just my luck. I need opinions please.
