Im out mowing today. All of a sudden , nothing is coming out of the deck. Sure enough, the belt broke. Oddly enough a small piece of wood had gotten wedged in the engine pulley and had caused the belt to break. So, I get a new belt. I'm a bit confused for a few minutes till i figure out that I gotta loosen up the bolt on the idler bracket. Somehow I manage to pop the belt tension spring off. (keep in mind, the mower is still on my trailer.) I get the belt on and I'm trying to figure out how to get this humongous spring back into place. Keep in mind I'm in the field and have limited tools. I finally settle on tying a piece of string trimmer line to my trailer an the other to the tension spring. I turn on the mower and slowly back up the mower causing he spring to stretch just enough to pop it back over the retaining lug.
