The deck drive belt broke on my Lazer Z on the first yard this morning. Not that big of a deal I always keep a spare, had it changed in no time. After I had the new one on and started back my mower would only run at about half throttle. All i can figure is when the belt broke it flew up and hit the throttle linkage. It all looked good, nothing bent that I could tell. I adjusted on it 2 or 3 times to finally get it back to full throttle. Strange, never had that to happen.
