Replacement for Genuine Toro 107-3779 Grass Bag Cloth OEM Only Lawn Mowers 20016 20017 20018 20019

What It Is

This is a genuine Toro OEM replacement grass bag cloth (part number 107-3779) designed for select Toro rear-bagging walk-behind mowers. It captures clippings during mulching or bagging operation and is a direct replacement for the original bag on models 20016, 20017, 20018, and 20019.

Fitment & Compatibility

Before buying, confirm your mower model number—this bag fits only Toro models 20016 (22” Personal Pace), 20017, 20018, and 20019. It is not compatible with other Toro series (e.g., Super Recycler, TimeCutter, or older 20000-series variants). Check your mower’s deck size: these models all use a 22-inch cutting deck. Measure the bag attachment hooks and chute opening—OEM cloth is shaped precisely for these models, so aftermarket alternatives may not seal correctly or clip on securely. This is genuine Toro, not a third-party copy.

Key Things to Know

• Quality: OEM cloth is thicker and more durable than most aftermarket bags—expect 2–3 seasons of regular use before fading or fraying.
• Installation: Simple slide-on and clip attachment; no tools required. Ensure the bag frame is not bent or rusted, or the cloth won’t fit snugly.
• Common gotcha: The bag cloth alone does not include the frame, straps, or hardware—you must reuse your existing frame. If your frame is damaged, you’ll need to buy it separately.
• Price premium: At $133.99, it’s 2–3x the cost of generic bags, but you’re paying for exact fit and longer life.

Should You Buy It

Buy this if you own one of the four listed Toro models and want a guaranteed, no-hassle replacement that seals properly to prevent clippings from blowing out. It’s the right choice for users who prioritize durability and exact fit over saving money. If you’re on a tight budget or your model isn’t listed, look for a universal bag with adjustable hooks—but expect a less secure fit.
