  • KEVLAR CORD DESIGNM154621 X300 42 Inch Deck Belt Built with a Kevlar cord so the belt works as intended during mowing. Designed for uneven terrain and yard work scenarios, it requires fewer readjustments and stays properly seated on the pulleys.
  • MULTI-PLY FABRIC BUILDThe M154621 mower belt features a multi-ply fabric build with the seam placed on the opposite side of the belt. This layout moves the seam away from the pulley path and is intended for consistent belt behavior during mowing.

  • OEM & MODEL MATCHINGIf the belt doesn’t match your machine, the lawn mower may not move properly. Match your OEM number or look the application chart below for your model.
