I just bought a used Lesco 52" hydro with a fixed deck. the belt was a little bit raggedy so I installed a new one. I then dropped the deck to the lower setting, and less than 10 hours later the new belt was all chewed up. I know I should have paid more attention to how the belt was doing. I did adjust the tension after the first couple of hours, but I'm wondering what to do now. it seems like the problem is that the top edge of the belt rubs against the lip on the tension pulley when the deck is in the lower setting. I'm not sure if there's a way to raise that pulley (maybe with spacers?) or what. I have searched around on the site and found a few other people complaining about their lesco mowers chewing up belts. I did look at the suggestions that envy posted a few years ago about them, but it didn't seem to apply to this situation. any help would be appreciated.
