Mower Deck Spindle Assembly
The spindle assembly houses the high-speed bearings responsible for blade rotation. A grinding noise indicates that the internal bearing races have become pitted or the lubrication has dissipated, causing metal-on-metal friction that is amplified by the mower deck's shell. Replacing the entire assembly is the standard forensic fix as the housing often suffers thermal expansion damage during bearing failure.

Mower Deck Flat Idler Pulley
This pulley provides tension to the deck belt when the PTO is engaged. If the internal bearings of the pulley seize or lose their tolerance, they will produce a loud grinding or whining sound only when the belt is under tension. The centrifugal force and belt load exacerbate the noise during blade operation.

Mower Deck Drive Belt
While usually responsible for squealing, a belt that has started to delaminate or has been damaged by a seized pulley can create a rhythmic grinding sound as it passes through the guards and pulleys. Friction against a stuck idler arm or a bent belt guard can also simulate a mechanical grind.
