Deck Spindle Assembly
The spindle contains high-speed ball bearings that support the blade shaft. When the seals fail, moisture and debris enter the bearing race, causing metal-on-metal grinding that intensifies under the centrifugal load of the spinning blades. Replacing the full assembly is the engineering standard as the housing is often heat-damaged once grinding is audible.

Deck Idler Pulley
Idler pulleys maintain tension on the deck drive belt and contain internal bearings that are under constant lateral pressure. If the bearing cage fails, the pulley will tilt and grind against its mounting bracket or rotate roughly only when the PTO belt is tensioned. This matches the symptom of noise occurring specifically when the blades are engaged.

Electric PTO Clutch
The electromagnetic clutch uses a friction disc and internal bearings to bridge engine torque to the mower deck. If the internal friction plate is warped or the air gap is insufficient, it can produce a grinding or heavy metallic scraping sound during engagement. While more expensive, it is a critical failure point in the drive transition.
