MTD RLM mod # 144Q845H088 TMO-3398005 has a B&S 42A707 1237 Purchased this from a man who says it had been sitting a while.... The transmission has 14 forward speeds, 7 low, 7 high. First thing I noticed is the variable speed pulley (VSP) does not variable. So I removed and cleaned and got the center to move easily up/down the shaft. Lubbed and replaced. After freeing up the VSP, the mower now goes nowhere. Before removing the VSP, the RLM would move, but only at the speed of a snail. Forward or reverse. There is a spring tensioned idler pulley that maintains belt tension at the transmission. After releasing the brake, the belt tensioning idler pulley and the pulley atop the transmission, are touching....this was happening even before I removed the VSP for maintenance. NOTE: there is a rod that connects the brake to the spring loaded arm that the VSP is mounted to, there is another rod that connects to that arm and continues backwards to my transmission speed selector on the fender, the speed selector rod was bent when I got the mower. So I straightened and reinstalled.... There is an adjusment ferrule (honest, I looked it up) at the end of the rod that connects to the speed selector assy. Do I simply need to adjust the ferrule ? Are the belts the culprit ? Did the chicken really want to cross the road ? Where should I start and what should I do.... More importantly, why does this happen to me..... LOL, jk.
