Side Discharge Chute Compatible with S-napper 21" Lawn mower, Fits 6.75 Self Propelled SP70

What It Is

A molded plastic side discharge chute for Snapper 21-inch walk-behind mowers, specifically designed to replace a broken or missing chute that directs clippings out the side deck opening. This aftermarket part fits Snapper’s 6.75 ft-lb self-propelled SP70 model and similar 21-inch deck machines.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 21 inches wide (measure deck shell, not blade path). This chute is engineered for Snapper’s SP70 self-propelled models with a 6.75 ft-lb engine, but may also fit other Snapper 21-inch walk-behinds with the same deck shape. Check the OEM part number—this replaces Snapper # 7078047YP or 7078047. If your mower uses a different chute mounting tab or spring clip design (e.g., older rear-baggers), it likely won’t work. Measure the width of your original chute’s mounting flange and compare to this unit’s dimensions (typically about 3.5 x 5 inches at the deck opening). Aftermarket fit can be slightly tight; minor trimming with a utility knife may be needed for a perfect snap-in.

Key Things to Know

• Material & durability: Molded polyethylene is sturdy but can crack if overtightened or hit hard. Avoid forcing it past the deck tabs.
• Installation: Usually a 5-minute job—slide the chute onto the deck’s side port and secure with the existing spring clip or bolt. No tools required for most Snapper models.
• Common gotcha: The chute may not seal perfectly against the deck if your mower’s mounting tabs are bent or worn. Inspect tabs and clean debris before installing.
• Mulching vs. bagging: This chute is for side discharge only. If you switch between bagging and discharging, keep the original chute or buy a dedicated mulching plug separately.

Should You Buy It

If your Snapper SP70’s original chute is cracked, lost, or missing and you want a quick, affordable fix for side discharge mowing, this $16 aftermarket chute is a solid bet. It’s not OEM, but it’s cheap and works for most 21-inch Snapper self-propelled models—just verify your deck tabs are intact and the part number matches.
