Blade Spindle Assembly
The grinding noise under load is a classic indicator of collapsed ball bearings within the spindle housing. When the PTO is engaged, the high RPMs cause a wobbling effect (eccentric rotation) that allows the mower blade to strike the deck's internal baffles or the neighboring blade. Replacing the entire assembly ensures the shaft, bearings, and housing are properly aligned and lubricated.
