115-4664 Grass Bag - NO Metal Frame, Compatible with Toro Lawn Mower XT675 59307 22" Lawn Mower 2009, Fits Model 20330 20331 20370 20371 20377 20378 & More

What It Is

This is a replacement grass collection bag (OEM part 115-4664) for select Toro 22-inch walk-behind lawn mowers. It attaches to the rear discharge chute without a metal frame, designed for bagging clippings during routine mowing.

Fitment & Compatibility

Before buying, confirm your mower model number (stamped under the seat or on the engine shroud). This bag fits Toro models 20330, 20331, 20370, 20371, 20377, 20378, and the XT675 (59307) from 2009. It is not compatible with mowers that use a metal frame bag—check if your original bag had a metal support structure. Deck size must be exactly 22 inches; no other deck widths work. This is an OEM Toro part, not aftermarket, so fitment is guaranteed for listed models.

Key Things to Know

• Low rating (2.2/5) – Reviews suggest poor durability; the bag may tear or detach quickly under normal use.
• No metal frame – The bag relies on plastic hooks and straps to attach. Check that your mower’s mounting points are intact.
• Installation is simple – No tools required; slide bag onto chute and secure with built-in clips. But ensure the bag’s attachment hooks match your mower’s latch style.
• Not universal – Double-check your model number on Toro’s site or the part itself. Wrong fit wastes time and money.

Should You Buy It

Only buy this if you own one of the exact Toro models listed and need a direct OEM replacement—and you’re willing to risk low durability for the convenience of no-frame bagging. Most users would be better off upgrading to a metal-framed alternative or a sturdier aftermarket bag, unless you’re on a tight budget and mow light grass infrequently.
