Best Lawn Mower Discharge Chute Covers for Walk-Behind and Riding Mowers
The best lawn mower discharge chute cover depends on your mower’s model and deck: the DECKMAN 731-07131 is best for several walk-behind models, while the GY20647 kit is intended for John Deere 42-inch mower decks. HASMX and 731-07486 options also target specific walk-behind mowers, and the Earthtec shield is listed for a 42-inch riding mower chute. Match the replacement part number and mower model before ordering; similar-looking parts may not fit.

DECKMAN 731-07131 Side Discharge Chute
This replacement chute is listed as part numbers 731-07131 and 731-7131. Its stated dimensions are approximately 11 inches long, 7.25 inches wide, and 3.4 inches high. The product information names MTD, Cub Cadet, Craftsman, Murray, and Troy-Bilt mower families, with specific Craftsman and walk-behind models also listed.
Best for: Owners of a listed compatible push or self-propelled mower who need the 731-07131 style side discharge chute. It was selected for its broad set of named mower models and clear part-number identification. Check your mower’s model number and the listed fit before ordering; brand name alone does not confirm compatibility.
John Deere 42-Inch Chute Cover Kit
This kit is designed for John Deere riding lawn tractors using a 42-inch mower deck and is listed as a replacement for part number GY20647. The package includes the chute cover and mounting hardware, so the listed components for installation come together in one kit.
Best for: A John Deere riding mower owner whose deck size and required replacement part match the listing. It stands out for specifying the 42-inch deck and including hardware. Limitation: The supplied information does not name individual tractor models, so verify that your mower uses GY20647 rather than relying on deck size alone.
Earthtec 130968X428 Deflector Shield
The Earthtec listing describes a replacement deflector shield for a 42-inch riding mower chute and identifies part number 130968X428. The product information is brief, but it gives a part number and deck-size description that can help narrow down the intended replacement.
Best for: Buyers who have confirmed that their existing shield or mower parts reference 130968X428. It was selected as a specific riding-mower deflector option. Limitation: The listing details provided do not identify mower makes or models, so confirm the part number and physical fit before purchase.
HASMX 731-07131 Side Discharge Cover
HASMX identifies this as a new side discharge chute cover with part numbers 731-07131 and 73107131. Its fit information includes selected MTD and Troy-Bilt walk-behind mowers, with examples such as TB110 and several model-numbered push or self-propelled machines. The listing also names Cub Cadet models including SC100, SC300, and SC500 variants.
Best for: Owners whose mower appears in the provided model list and uses part 731-07131. The specific model examples make it useful for checking fit against an existing mower label. Limitation: The listed fit is model-specific; confirm the full model number and part number, especially if the mower is a different year or configuration.
731-07486 Side Discharge Chute
This side discharge chute is listed as part 731-07486 for MTD 21-inch-deck self-propelled lawn mowers. The product information names Troy-Bilt TB110, TB130, and TB1100, along with Craftsman, Cub Cadet, Yard-Man, and Yard Machines mower families.
Best for: A buyer whose mower uses part 731-07486 and matches the listed 21-inch-deck application. It was selected as an alternative to 731-07131 for models identified under a different part number. Limitation: Do not treat the two part numbers as interchangeable; confirm the correct number for your exact mower.
Buying Guide: How to Choose a Discharge Chute Cover
How do you confirm the right replacement?
Start with the mower’s model number, usually printed on a label on the mower or frame. Compare that number with the product’s fit list, then check the part number on the old chute or in the mower’s parts information. A matching brand or deck size is not enough when the listing does not specify your exact model.
Does your mower use a walk-behind or riding-mower part?
Walk-behind options in this list include the DECKMAN and HASMX 731-07131 covers and the 731-07486 chute. The John Deere GY20647 kit and Earthtec 130968X428 shield are described for 42-inch riding mower applications. Choose by mower type and part number, not by the general phrase “discharge chute cover.”
Should you choose a kit with hardware?
A kit that includes mounting hardware may be convenient if you need those components for installation. The John Deere option explicitly lists hardware with its cover. The other product details do not specify included hardware, so check the listing if you need mounting pieces.
What if two options list similar mower brands?
Compare the complete model number and replacement part number. For example, 731-07131 and 731-07486 are separate listed part numbers, even though both are associated with walk-behind mower brands in the supplied product details. Avoid choosing based only on a shared manufacturer name.
Frequently Asked Questions
What does a lawn mower discharge chute cover do?
It is the cover or deflector component associated with the mower’s side discharge opening. Select a replacement intended for the mower’s specific design and part number.
Are 731-07131 and 731-7131 the same part number?
The DECKMAN listing identifies both 731-07131 and 731-7131. Confirm your mower’s part reference against the product listing before ordering.
Can a 42-inch cover fit every riding mower?
No. Deck size alone does not establish compatibility. The John Deere kit is listed for 42-inch decks and part GY20647; the Earthtec shield is listed for part 130968X428. Verify the exact part reference.
Which option is intended for Troy-Bilt TB110?
The supplied fit details name TB110 for the HASMX 731-07131 cover and the 731-07486 chute. Check the mower’s full model number and existing part number to determine which listing applies.
