I am experiencing the same problem. I bought my LGT2654 in the summer of 2014 and it ran very well. As of this year I had a plethora of things happen. I had to replace the front wheel bearings, the muffler and now the drive belt keeps falling off. I bought a new belt and it worked for one cutting session (I Have 3 acres) and on the next one it fell off again, and again, and again!! I am an amputee (right leg) and I can't be making these repairs all the time. There should be no reason to make those types of repairs after only 2-3 summers of work anyway. I had to use my neighbors John Deere to cut my yard(very embarrassing). Is there a problem with that year of models all together? By the looks of these similar posts, it seems as though it is. Thank you.
