Mandrel Assembly (Spindle)
The spindle bearings are the primary rotating components under load when the blades are engaged. Grinding indicates that the internal bearing races have suffered catastrophic fatigue or contamination, leading to metal-on-metal friction at high RPM. Replacing the entire assembly is necessary as the aluminum housing often sustains heat damage or bore expansion when the bearings fail.

Deck Idler Pulley
When the PTO is engaged, the tensioner arm moves to tighten the belt, putting significant lateral pressure on the idler pulleys. If the internal bearings of the idler pulley have seized or lost lubrication, they will emit a loud grinding or screaming sound only when the belt is under tension. This part is a secondary failure point for noise issues localized to the mower deck.

Mower Deck Drive Belt
While usually associated with squealing, a belt that has suffered 'chunking' or has embedded debris can create a rhythmic grinding or heavy thumping sound as it passes through the pulleys. If the belt has been slipping due to a seized spindle, the friction can glaze the belt and damage the reinforcement cords, leading to mechanical noise during engagement.
