Question about Craftsman 48" Cut Riding Lawn Mower Deck Belt 174368
I own a Craftsman rider, DTY 4000, 25 HP Kohler, 48" cut, 137 Hrs. It eats a belt about every mowing or two. Did all the stuff you did. Good luck from Sears. Had cousin who is owns a lawn & garden repair business look at it today. Says the prob. is this - The drive belt pulley (elec clutch) has too a narrow "V" and the angle of wear between it and the deck when the deck is in the lowered (mowing) position is too severe. If you notice with the deck in the fully raised position the pulleys line up perfectly. Then drop your deck and see how tightly bent the belt is downward and it makes sense as to why(my) belt would first roll over then break in a few minutes. The elec clutch pulley is sold as one unit PT No. 179334 $250.00, but I'm sure it would come with the same narrow V pulley. Waiting for word from my cousin. My last Sears Mower. Cannot even sell it in good faith.

FINAL SOLUTION TO FIX THE BELT FROM COMING OFF LT1045 WHILE MOWING!
I also had this issue with my LT1045 belt. However, I just figured out how to finally fix / re-engineer my LT1045 Cub Cadet from having issues with the belt coming off of the deck while mowing.
Taking it back into a shop for repairs will not work, the belt will just come off again the first time you mow. I am making a YouTube Video to help others like me with this mower issue and will post a link here soon showing how to fix this design flaw.
It took me about an hour to fix but I've got it working now with no problems, minimum vibrations and belt is running cool now! I've gone for 2 months with no problems now. Check back soon for the link!! I expect I will have the video tutorial finished within a week!!
