Mower Deck Spindle Assembly
The grinding sound is the result of mechanical friction from failed internal ball bearings within the spindle housing. When the PTO clutch engages, the belt tension applies a lateral load to the spindle shaft, forcing damaged rolling elements against a pitted race at high RPMs. Replacing the entire assembly is the engineered solution as these spindles are typically non-serviceable sealed units.

Deck Idler Pulley
Secondary potential failure point where the internal bearing of the tensioning pulley fails. If the pulley bearing seizes or loses its race integrity, it will emit a high-pitched grinding or screaming noise specifically when the belt is under tension during blade engagement.

Electric PTO Clutch
The internal friction plate or the integrated bearing of the clutch assembly may have suffered thermal deformation. If the grinding is localized under the engine crankshaft rather than the deck, the clutch's internal bearing has reached its L10 fatigue life limit.
