  • A: Howdy neighbor! The 21-inch mulching blade (Manufacturer Part Number 490-100-C089) will not fit your mower. Your 33-inch wide-area walk-behind machine relies on a pair of smaller, overlapping 17.9-inch blades to match the width of the deck without colliding. To get your mower cutting perfectly again, you will want to pick up a pair of official Cub Cadet 33-inch Deck Blades (Part Number 942-04154A), which are engineered explicitly for your twin-blade, caster-wheel model.

Q: I have cub cadet sc500z it dose't bag the grass dose't pick up what do i have to do to fix it

1 Answer
  • A: Hello Sanyo. make sure you are not cutting very long or wet grass. Also check the connections to the bagger and make sure the plug on the side of the deck is secure to make the air flow go directly to your grass bagger. Thank you for your question!
