Humboldt John Deere™ New Rear Rider replacement grass bag. Bag ONLY - Price is per single bag MADE IN THE USA

What It Is

This is a single replacement grass collection bag for John Deere rear-engine riding mowers. It’s designed to fit select models using a 30-inch or 38-inch cutting deck, sold as a standalone bag (no frame or hardware included).

Fitment & Compatibility

• Check your mower model: Fits John Deere rear riders like the SRX, SX, and select 100-series (e.g., SRX75, SX75, SX95, 105, 125). Does not fit X300-series or zero-turn models.
• Deck size: Works with 30-inch and 38-inch decks only—verify your deck width before ordering.
• OEM vs aftermarket: This is a direct replacement for John Deere OEM bag part numbers GY20785, GY21148, and GY21395. If your mower uses those numbers, this bag will fit.
• Measurements: Bag dimensions are roughly 24”L x 16”W x 14”H. Compare against your current bag to confirm shape and hook alignment.
• Frame not included: You must reuse your existing bag frame or purchase one separately. The bag attaches via two top hooks and a bottom snap.

Key Things to Know

• Made in the USA – Humboldt uses heavy-duty woven polypropylene, which is more tear-resistant than many OEM bags.
• Installation is simple – Takes about 2 minutes: slide the frame into the bag, snap the bottom, and hook onto the mower. No tools needed.
• Capacity is unchanged – Holds the same volume as the OEM bag (approx. 6 bushels). Don’t expect more capacity than stock.
• Common gotcha – The bag’s top hooks are slightly thicker than OEM. If your frame is old or bent, you may need to gently squeeze the hooks to get a snug fit.

Should You Buy It

Buy this bag if you need a direct, durable replacement for your John Deere rear rider’s grass bag and want USA-made quality. It’s a better value than OEM for the same fit and function, but only if your existing frame is in good shape. Skip it if you need a complete bagger system or have a non-compatible mower model.
