Description

Designed for compatible 42-in Deck applications, the M174994 deck belt replacement is made for select John Deere mowers & more. It replaces OEM part number M174994 and provides a clear reference for matching the original belt during routine deck maintenance.

Strength, flexibility and durability for repeated deck operation are provided by aramid tensile cords, a natural rubber body and a two layer wrapping cover. Lab-tested low friction and minimum wear mean long-lasting performance, and high breaking strength helps the belt cope with heavy operating loads. All compatible lawn mower models are listed below.

Replace the installed deck belt when wear is evident, or as part of scheduled maintenance of the mower. Before ordering, please check the original OEM belt number, full mower model and deck size.
