Mower Deck Spindle Assembly
The spindle contains sealed ball bearings that support the blade's rotation; when these bearings fail due to seal breach or impact, they produce a heavy grinding noise under the centrifugal load of the engaged blades. Replacing the entire assembly is the standard resolution as the bearings are typically pressed into a non-serviceable housing.

Deck Idler Pulley
The idler pulley maintains tension on the deck belt only when the PTO is engaged. If the internal bearing race is pitted, the increased belt tension during blade engagement forces the balls against the damaged race, resulting in a loud, metallic grinding sound that vanishes when the blades are disengaged.

Deck Drive Belt
While belts usually squeal, a belt that has partially delaminated or has 'slugged' (flat spots) can strike the belt guards or the spindle housing at high speeds, creating a rhythmic grinding or slapping sound that correlates with blade engagement.
