Main Features

Complete 42-Inch Deck Rebuild Set

The kit combines several commonly replaced mower deck components in one package. Replacing worn spindles, pulleys, and the belt together can make a deck refresh more convenient than sourcing each component separately.

Replacement Spindle Assemblies

Two spindle assemblies are included to replace worn or damaged spindle components on compatible 42-inch decks. Proper spindle operation is essential for maintaining consistent blade rotation and cutting performance.

Durable Idler Pulleys

The two included 756-04129 idler pulleys help maintain proper belt routing and tension. Replacing worn pulleys can help reduce unwanted belt movement, noise, and vibration.
