Alright, so my grandmother owns a LTX 1050 with the 50" deck, and as I was mowing her lawn - the deck belt snapped. I had never replaced a deck belt, but I figure - Hey I'm smart, I can figure this out. Thus begins the hellish process. Anyway, I picked up the belt 50" belt that the deck requires, as per the manual. I removed the deck with minimal strain, watched a couple youtube videos, got the belt on correctly, but then I hit a wall. I couldn't get the deck reattached with it on the front PTO pulley, and then vice versa - I couldn't get the belt on the PTO pulley with the deck attached in the rear. So after messing with it for hours thinking I was missing something, I had my boyfriend come over. We lifted the front of the mower, and removed the pins for the deck lever so we could properly realign the deck. Success! We got the deck reattached with the belt also attached. I head out to test it, and the belt pops off as soon as I engaged the blades. Well crap. We figure, hey...maybe the belt wasn't attached all the way, so we go through the motions (much more thorough mind you) and the whole way through we made sure the belt was around each pulley. Take it back out, belt pops back off again! So after a string of obscenities, I park the mower, feeling absolutely defeated. She called the local lawnmower repair shop, and they said it will be at least 2 weeks, and upwards of $400 (and that's with little explanation of the problem). They are trying to hang my grandmother out to dry! I can't have this! Someone out there must know something about this problem, and it can't be that difficult of a fix. PLEASE, someone guide me! :confused2:
