I have a 6' KK Rotary Mower, I drove through a bush and the engine stopped. I lowered the lever to stop the mower, restarted the engine, lifted the mower up, then moved to a clear spot. Now, I pulled up the lever to engage the mower again, then started to cut more tall weed, it only cut about 5 feet, then the mower stopped. I tried that a few times, the same things happened. I tried to search on the internet, but could not find any similar problem. I would like to post on this forum, hopefully, someone knowledgeable on this type of mower can help me. Thank you very much in advance. TT.
