964-04154A Lawn Mower Grass Bag Replacement Compatible with Crafts man 21" Lawn Mower 24737110, 24737034, 24737037, Replaces 964-04154 (Without Grass Catcher Frame)

What It Is

This is a replacement grass collection bag for 21" Craftsman walk-behind mowers, specifically designed to fit models 24737110, 24737034, and 24737037. It replaces OEM part 964-04154 and is sold without the grass catcher frame—you must reuse your existing frame.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Only for 21" Craftsman mowers with a cutting deck of that size. Measure your deck width if unsure.
• Model number: Check your mower’s model plate (usually under the seat or on the deck). This bag works with 24737110, 24737034, and 24737037. It may also fit other Craftsman models using OEM part 964-04154, but these are the confirmed matches.
• Frame requirement: This bag does NOT include the frame. You must have a compatible grass catcher frame from your original bag. If your frame is broken or missing, buy a frame separately or look for a bag+frame combo.

Measure the bag opening dimensions (approx. 12" x 8") and compare to your frame’s attachment points. The bag attaches via a zipper or hook-and-loop closure around the frame.

Key Things to Know

• Quality vs. OEM: This aftermarket bag is generally functional but may have thinner material or less durable zippers than the OEM Craftsman bag. Expect it to last 1-2 seasons with regular use.
• Installation: Easy—slide the bag over your existing frame, secure with the zipper or Velcro, and attach to the mower’s discharge chute. No tools required.
• Common gotcha: The bag may fit loosely or sag if your frame is slightly bent. Inspect your frame for damage before ordering.
• Capacity: Same as OEM (approx. 2 bushels). Works well for standard residential lawns but may require frequent emptying for thick, wet grass.

Should You Buy It

Buy this if your original Craftsman bag has ripped or worn out and your frame is still in good shape, and you want a budget-friendly replacement that fits the specific 21" models listed. Skip it if you need a frame, want a sturdier bag for heavy use, or have a different Craftsman model number—check fitment first.
