Deck Drive Belt (54-inch)
The belt is the primary component requiring routing; over time, the rubber compound undergoes thermal degradation and elongation. This stretching reduces the belt's ability to wedge into the pulley grooves, leading to slippage and centrifugal ejection during high-load blade engagement.

CONF
Deck Tensioner Spring
This extension spring maintains the 'Hooke's Law' force required to keep the idler pulley pressed against the belt. If the spring fatigues or loses its K-constant, it cannot counteract the belt 'whip' created by spindle vibrations, allowing the belt to jump the pulley flange.

CONF
Flat Idler Pulley
The internal bearings of the idler pulley often develop radial play; as the bearing wears, the pulley tilts under the tension of the drive belt. This misalignment creates a 'lead-out' angle that forces the belt to walk off the edge of the pulley regardless of the routing accuracy.
