I recently replaced the drive belt on my 25hp 54in cut Troy bilt. I spent alot of time trying to get the springs and the tension right. I have 1 acre of land, the mower was driving perfect then toward the end it started acting funny. I would have to let of the gas pedal and keep pushing it, I finished the cut and when I was washing the deck I saw 1 of the springs were hanging so I assumed that was the problem. I pulled the deck off replaced the spring crimping the end a little tighter and started cutting grass and not long after starting acting up again. I tried the springs in several positions and adjusted the tension several different ways. Everything seams to be tight when the pedal is pushed, tranny pullies and everything are turning. When I push the pedal it will move slow then stop, tried H and L gear and reverse all the same, Any idea's? Thanks
