ECOTRIC 46" Deck Grass Catcher Bagger Chute Replacement for 405455 532405455

What It Is

This is an aftermarket grass catcher chute for 46-inch lawn tractor decks. It replaces OEM part numbers 405455 and 532405455, directing clippings from the deck discharge into a rear bagger system.

Fitment & Compatibility

Critical checks before buying:

• Deck size: Only fits 46-inch cutting decks—not 42″, 48″, or 54″.
• Brand/model: Designed for select MTD, Troy-Bilt, Craftsman, and Yard-Man tractors with a 46″ deck and rear bagger. Verify your tractor’s OEM part number is 405455 or 532405455.
• Connection type: This chute attaches to the deck discharge opening and the bagger hose/elbow. Measure your deck’s discharge opening width (approx. 5″ x 7″) and bagger tube diameter (typically 5″) to confirm.
• OEM vs aftermarket: ECOTRIC is an aftermarket brand. Fitment may vary slightly from OEM—check customer reviews for your specific model number before buying.

Key Things to Know

• Material: Polyethylene plastic—durable but can crack if overtightened or hit hard. Avoid over-torquing mounting bolts.
• Installation: Typically bolts directly to the deck and bagger tube with included hardware. Expect 15–30 minutes; no special tools needed. Clearance under some decks may be tight.
• Common gotchas: Some users report the chute doesn’t seal perfectly with the bagger tube, causing grass blowout. You may need a gasket or weather stripping for a tight fit. Also, check that the chute’s shape doesn’t interfere with deck belt or spindle pulleys.
• Ratings note: 3.4 stars from 135 reviews—mixed. Many praise the price, but some cite fitment issues or premature cracking.

Should You Buy It

This is a budget-friendly replacement if you own a compatible 46″ MTD-style tractor and don’t mind minor adjustments for a proper seal. Avoid if you want OEM-level fit or have a non-standard deck/bagger setup—spend more for an OEM chute instead.
