Mower Deck Drive Belt
The V-belt profile narrows over time due to abrasive wear against the pulleys, causing it to sit lower in the sheaves and lose effective tension. This reduction in surface contact area leads to slipping under heavy grass loads as the friction limit is exceeded.

Deck Engagement Tension Spring
This extension spring provides the mechanical force required to hold the idler pulley against the belt. Over time, the spring steel undergoes plastic deformation or fatigue, resulting in lower spring rate and insufficient pressure to maintain belt grip during PTO engagement.

Flat Idler Pulley
Bearing failure or surface wear on the idler pulley increases rotational resistance. This drag creates heat which further glazes the belt surface and can cause the idler arm to vibrate, momentarily reducing belt tension and allowing it to slip or jump.
