hello everyone, I have the lx1842 and the pto was never engaging, so I figured to buy a new belt. After I installed it, the pto did engage and I was finally able to cut the grass for a couple of days. Then to make a long story short, the belt had gotten loose, and I was no longer able to cut the grass.. I'm figuring the pulleys need to be tightened, as well as some other things too. Btw I bought the MaxPower 336352 drive belt, and I later saw in user reviews that it comes a little loose to begin with, which is terrible. $25.00 down the drain. Can anyone possibly tell me how to get the belt tighter, because I'm not seeing how to do this in the user manual. Any help or advice would be great. Thanks
