Last year I repowered my 10ML60 with something similar to a powerfist, and restored the mower deck. I took the mower out this year, fired it up, and found that the mower pulley tensioner wouldn't engage. I pushed the lever forward to start the blade and nothing happened. I don't remember doing anything to it when I put it away last year, but this year when I engage it, it puts no tension on the belt. My screwing around with it eventually broke the spring that supposed to tension it. I've looked and looked at it, and can't figure out how it's supposed to work. When I tried to engage the pulley, the lever position actually reduced the spring tension, the way the spring was attached, and with no force against the belt, it did nothing. I'm left scratching my head. This should be obvious, but I'm unfamiliar with these. Does the tensioner pulley go on the inside or outside of the belt? How does the spring hook up? Does anyone have a picture of a similar one they can share of a working tensioner so I can get this thing going again?
