9934059 Posted April 23, 2006 Posted April 23, 2006 I have a Simplicity 5212.5 and am having difficulty getting the drive belt tension adjusted so that the mower deck engagement lever fully engages (replacing a broken belt). I have tried to adjust the collar to the spring. All of this resides within a rod guide assembly. The Simplicity owner's manual describes the procedure and shows the 42 inch mower deck graphic but the belt tensioning mechanism is configured differently than the 36 inch deck and mine is a 1690839. Any suggestions??
