18-Inch/20-Inch Reel Mower Grass Catcher, Grass Catcher for Reel Push Mower

What It Is

This is a universal grass catcher bag designed for 18-inch and 20-inch reel push mowers. It attaches to the rear of the mower to collect clippings during use, saving you from raking.

Fitment & Compatibility

• Deck size: Only fits reel mowers with 18-inch or 20-inch cutting decks. Measure your mower’s deck width before ordering.
• Mounting: The bag has a metal frame that slides onto two rear mounting pins. Check that your mower has these pins (most reel mowers do, but some budget models may lack them).
• Brand/model: This is a generic aftermarket bag, not OEM. It may fit common brands like American Lawn Mower, Great States, Sun Joe, and Scotts, but always verify pin spacing and bag hook shape.
• Measurements: Bag dimensions are roughly 18 x 12 x 8 inches. Confirm your mower’s rear clearance (at least 6 inches) so the bag doesn’t drag.

Key Things to Know

• Poor build quality: Many reviews report the bag tears at seams or the frame bends after a few uses. Expect limited durability for heavy or tall grass.
• Installation is simple: Slides on in seconds with no tools, but the fit can be loose—some users add zip ties or tape to keep it secure.
• Capacity is small: At about 1.5 bushels, it fills quickly (every 3-4 passes on a medium lawn). Frequent emptying is needed.
• Not universal despite claims: The 2.4-star rating reflects frequent fitment issues—if your mower’s mounting pins are not exactly 12 inches apart, the bag may not stay on.

Should You Buy It

This bag is only worth it if you have a standard 18- or 20-inch reel mower with rear pins and you need a cheap, temporary solution for light grass. For frequent use, thicker grass, or a better fit, spend $10–$15 more on a brand-specific OEM bag.
