Hi all, I have an MTD 604 (model number 13AV604G671). I purchased this machine second hand and the motor runs well but have had a continuous problem with belts snapping.
I have been using high-quality parts not cheap belts. The local mower shop has "had a look" but cannot see any problem (although happy to sell me more belts..!) Despite this, I only get a few hours (4?) of mowing before the belt gives up and snaps. This is ridiculous.
Now, I have done a bit of detective work. Having just replaced the belt (again!) I did 10min of mowing and inspected the belt. Clearly the top of the belt has rubbed to black while the bottom and outside remain as new. At least this eliminates half the belt path. There is one pulley that looks plain wrong to me so was hoping one of you may be able to clarify. I attach a photo of the deck showing the pulley in question - also a shot underneath to show what I think is a strange angle and with two possible rub points indicated.
What do you think?
