2 Pack 490-900-M061 Deck Wash Kit Replaces 490-900-0025 Including 921-04041 Lawn Mower Deck Wash Adapter Nozzle, 737-04003D Deck Wash Nozzle(Stainless Steel), 731-07487 Deck Wash Nozzle Review

Overview

If you’ve ever spent twenty minutes on your hands and knees scraping caked-on grass clippings from the underside of your mower deck, this 2-pack deck wash kit is the solution you didn’t know you needed. Designed as a direct replacement for popular John Deere and other-brand mower wash ports (including models using 490-900-0025, 921-04041, 737-04003D, and 731-07487), this kit gives you two complete stainless steel nozzles and adapters for under $20. It’s built for homeowners who want a fast, no-mess way to keep their mower deck clean without wrestling with a garden hose and a putty knife.

Who Should Buy This

• Homeowners with 1/2 to 2-acre lawns who mow weekly and deal with damp grass that clumps under the deck. If you’re tired of rust buildup and reduced cutting performance, this kit will save you time every single mow.
• DIY mechanics and equipment tinkerers who own multiple mowers or a zero-turn. The 2-pack lets you outfit two machines at once, or keep a spare on hand for when the original plastic nozzle cracks.
• Anyone replacing a worn or broken deck wash port on a John Deere, Husqvarna, or similar brand. These nozzles are a drop-in match for the common 490-900-M061 and 490-900-0025 patterns, so you won’t need to modify your mower’s mounting hole.
• Budget-conscious buyers who want stainless steel durability instead of the plastic nozzles that often split after a season. At $10 per nozzle, this kit undercuts most OEM replacements by half.

Key Features Breakdown

Stainless Steel Construction (921-04041 & 737-04003D)
Most OEM wash ports use plastic or brass. Plastic cracks in cold weather; brass can corrode over time. Stainless steel is the right call here—it resists rust from constant water exposure and won’t deform when you crank the hose fitting tight. The 737-04003D nozzle in this kit is machined, not stamped, so the threads are clean and won’t cross-thread on your mower deck.

2-Pack Value
You get two complete nozzle assemblies (each includes the adapter and the nozzle body). That means you can install one on your riding mower and keep the other for your zero-turn, or stash a backup in your garage. Given that a single OEM nozzle often runs $12–$15, the 2-pack at $19.99 is a no-brainer.

Direct Fit for Multiple Models
This kit replaces 490-900-0025, 921-04041, 737-04003D, and 731-07487. That covers a huge swath of John Deere 100, 300, and X-series riders, plus many Husqvarna, Craftsman, and MTD decks. The adapter threads into the standard 1/4-inch quick-connect port, and the nozzle itself screws into the deck’s existing hole—no drilling or adapter plates needed.

Universal Garden Hose Compatibility
The adapter uses a standard male quick-connect fitting that snaps onto any standard female garden hose end. No proprietary connectors or special tools required. Just click, turn on the water, and let the spinning deck blades do the cleaning.

Compact Design
Unlike some bulky wash ports that stick out and catch on tall grass or debris, these nozzles sit nearly flush with the deck surface. That means less risk of snapping them off on a rock or root, and they won’t interfere with blade removal during sharpening.

Pros

1. Stainless steel won’t rust or crack—I’ve watched plastic nozzles shatter in freezing temps. These will outlast your mower.
2. Two nozzles for the price of one OEM—At $19.99, you’re essentially getting a free spare. That’s real value.
3. Dead-simple installation—Unscrew the old nozzle, screw in the new one with a bit of PTFE tape, and you’re done. No special tools, no cussing.
4. Cleans thoroughly in under two minutes—With the blades engaged and water flowing, the spinning action flings clippings off the underside. You’ll see clean metal where there was once a green cake.
5. Universal fit for most riders—If your deck has a threaded hole (usually 1/4-inch NPT), this will likely work. The included adapters cover the two most common thread patterns.
6. Compact profile—No more snagging the wash port on branches or having it collect debris. It tucks away cleanly.

Cons

1. Not compatible with every brand—While it fits many John Deere and Husqvarna decks, some older MTD or Craftsman models use a different thread pitch. Measure your existing port before buying.
2. Requires a quick-connect hose fitting—If your garden hose doesn’t have a quick-connect end, you’ll need to add one (about $5 at any hardware store). Not a dealbreaker, but worth noting.
3. Doesn’t include the hose adapter—The kit gives you the nozzle and the deck-side adapter, but you’ll need your own male quick-connect for the hose. Most people have these, but it’s not “all-in-one.”
4. Stainless steel is heavier than plastic—It’s a minor weight addition to the deck, but negligible for mowing. More of a note than a true con.

Bottom Line

This 2-pack deck wash kit is one of those rare aftermarket purchases that actually outperforms the OEM part. The stainless steel construction eliminates the cracking and corrosion issues that plague plastic and brass nozzles, and the price is absurdly low for what you get. If you mow wet grass, live in a humid climate, or just hate scraping crusted clippings off your deck, buy this kit. Install it in five minutes, and you’ll wonder why you didn’t do it years ago. Strong recommendation for any homeowner with a compatible mower deck.

Frequently Asked Questions

Q: Will this fit my John Deere D140?
A: Most likely yes. The D140 uses the 490-900-0025 pattern, which is one of the direct replacements in this kit. The nozzle threads into the deck’s existing port—no modifications needed. If you’re unsure, check your deck for a threaded hole near the discharge chute.

Q: Can I use this with a pressure washer instead of a garden hose?
A: You can, but be careful. Pressure washers deliver much higher PSI, which can force water past seals and into blade bearings. Stick with a standard garden hose at full flow—it’s plenty of pressure to clean the deck without risking damage.
