Got it. 

 

My thought on this is as the blades are put under load of the heavier grass the spindle is allowing enough movement of the pulley to throw the belt. So checking for any movement of the spindle through the rotation could be the problem. Checking using the blades will give the leverage. So if the bearing even have one spot that is worn enough it would throw the belt. Pushing on one end of the blade towards the deck as it is rotated may find problem. Good luck finding what is causing this.

I will need to double check this.

Did it always throw the belt for you ?   Is there any adjustments to the deck front to back ? Maybe you could move the deck back further . When the belt come off does it give you any clues on where the problem might be , I would think the motor side would have a belt guard around the clutch that won't let it come off there

I have JD LX277. in the same way, I reattached all the knives, but I didn't get much results.

Has the belt tension spring gone lax?
