Lawnmower Grass Bag 964-04154A Fits Craftsman 21" Lawn Mower Bag Replacement Craftsman／MTD Lawn Mower 964-04154 - (NO Metal Frame)

What It Is

This is a replacement grass collection bag designed for 21-inch Craftsman and MTD walk-behind lawn mowers. It catches clippings during bagging operations, eliminating the need to rake or manually collect grass.

Fitment & Compatibility

Before buying, confirm your mower has a 21-inch cutting deck and uses a rear-mounted bag attachment system. This bag replaces OEM part number 964-04154 and fits most Craftsman models from the 2000s and 2010s, plus many MTD-built mowers sold under the Troy-Bilt, Cub Cadet, and Yard Machines brands. Measure the bag opening (roughly 8” x 6”) and compare to your mower’s discharge chute—some newer Craftsman models use a different attachment shape. This version does not include a metal frame; your mower must have a frame or bag support already attached. Check your owner’s manual or the model number on your mower’s deck for exact compatibility.

Key Things to Know

• No metal frame included – If your old bag had a wire or plastic frame that’s broken, this bag alone won’t work. You’ll need to reuse your existing frame or buy a separate frame kit.
• Installation difficulty – Easy, under 5 minutes. Slide the bag onto the mower’s bag holder hooks or frame, then secure the top strap. No tools required.
• Durability – Made of woven fabric with a plastic bottom. Some users report the fabric tears after 1-2 seasons with heavy use. Avoid overfilling or dragging over rough ground.
• Capacity – Holds roughly 1.5 bushels (about 12 gallons). Good for average lawns, but smaller than some premium bags. Expect more frequent emptying on dense, wet grass.

Should You Buy It

This is a solid budget option if your original Craftsman or MTD bag is worn out and your mower’s frame is intact. At $26.89, it’s cheaper than OEM replacements but not as durable. Best for light-to-medium use on small to average yards. Skip it if you need a heavy-duty bag or your mower’s frame is missing—you’ll need a frame kit or a different bag model.
