What It Is

This is a replacement grass catcher bag for Cub Cadet double-bagger systems (rear twin baggers). Designed to fit 42" and 50" deck models, it collects clippings during mowing for easy disposal.

Fitment & Compatibility

• OEM cross-reference: Replaces Cub Cadet part numbers 964-0221, 764-0221, and 764-0221P.
• Compatible models: Cub Cadet double bagger models 303, 310, 678, 847 (check your existing bagger’s model number—often stamped on the frame or bag).
• Deck size: Works with 42" and 50" decks. Does NOT fit 46" or 54" decks unless specifically confirmed.
• Measurement check: Bag dimensions are approximately 24" x 14" x 12". Measure your current bag’s mounting hooks and frame spacing. The attachment hooks must match the bagger frame’s rod diameter (typically 3/8").
• Before buying: Verify your bagger is a rear twin bagger (two bags side-by-side), not a single bag or side-discharge system. If you have a different brand bagger (e.g., MTD, Troy-Bilt), this likely won’t fit.

Key Things to Know

• Quality concerns: At 3.4 stars, some users report thinner fabric than OEM. Check for reinforced stitching at stress points (hooks and bottom seam) before first use.
• Installation: Straightforward—remove old bag, slide new bag onto the bagger frame hooks. No tools needed. Ensure the bag’s top flap aligns with the discharge chute.
• Durability: Not UV-treated like some OEM bags. Expect 1–2 seasons with regular use. Store indoors to extend life.
• Common gotcha: The bag may not seal perfectly against the chute, causing minor grass blow-by. Not a dealbreaker for most, but annoying if you want a clean catch.

Should You Buy It

If you have a compatible Cub Cadet double bagger and need a budget-friendly replacement for a worn-out OEM bag (which costs $80–$100), this is a decent short-term fix. Skip it if you mow heavy, wet grass frequently or want a bag that lasts more than two seasons—spend a bit more on an OEM or heavy-duty aftermarket option.
