970698001 20" Lawnmower Grass Bag for Ryobi 20" Lawn Mower Parts RY40108, RY40109 Fits Ryobi 40V Cordless Lawn Mower Models - (NO Metal Frame)

What It Is

This is a replacement grass bag for Ryobi 20-inch 40V cordless mowers, designed to catch clippings during mulching or bagging. It fits models RY40108 and RY40109, and is sold as an aftermarket part without a metal frame.

Fitment & Compatibility

• Deck size: Fits only 20-inch Ryobi mowers. Measure your deck width to confirm.
• Model check: Compatible with RY40108 and RY40109. Not for other Ryobi 40V mowers (e.g., RY40110 or 21-inch models) unless verified.
• OEM vs aftermarket: This is a third-party replacement, not an official Ryobi part. It may have slight differences in material thickness or fit.
• No metal frame: The bag attaches to your mower’s existing metal frame. If your original frame is bent or missing, this bag won’t work.
• Measurements: Approx 20" x 14" x 10", but check your mower’s bag mounting hooks and clearance before buying.

Key Things to Know

• Installation: Easy—slides onto the mower’s metal frame and hooks. No tools needed.
• Quality: Some users report thinner fabric than OEM, which may tear faster under heavy use or wet grass.
• Capacity: Holds about 1.5 bushels. Fine for small lawns, but frequent emptying needed on larger yards.
• Common gotcha: Ensure the bag’s attachment tabs align with your mower’s hooks. Slight warping can cause poor fit or clippings to spill.

Should You Buy It

Buy this if you need a budget-friendly replacement for a Ryobi RY40108 or RY40109 with a working metal frame and don’t mind slightly lighter fabric. Skip it if you want OEM durability or have a different Ryobi model—verify fit first to avoid return hassles.
