120-5225 Mulch Plug for Toro Ex-Mark 30" Timemaster and Turfmaster Lawn Mowers Fits ECKA30, ECS180CKA30000, 20199, 20200, 20975, 20976, 20978 Models

What It Is

The Toro 120-5225 is an OEM mulch plug designed to block the side discharge chute on select Toro Ex-Mark 30-inch Timemaster and Turfmaster mowers, converting them from bagging or side-discharge to mulching mode for finer grass clipping recirculation.

Fitment & Compatibility

Before buying, verify your mower’s model number—this plug fits specific 30-inch deck models only. Compatible models include: ECKA30, ECS180CKA30000, 20199, 20200, 20975, 20976, and 20978. It will not fit other Timemaster or Turfmaster 30-inch decks (e.g., 20334, 21030) without checking. Measure the chute opening: the plug’s dimensions are roughly 6.5 x 4.5 inches. It is OEM Toro, not aftermarket, so no adaptation needed. Check your deck’s side discharge chute for two mounting holes (approx. 3 inches apart) to confirm compatibility.

Key Things to Know

• Quality: OEM Toro plastic—durable but can crack if overtightened or forced. Avoid over-torquing the wing nut.
• Installation: Easy—slide plug into chute, secure with included wing nut and bolt. No tools required for most models, but some decks may need a wrench for the bolt.
• Common Gotcha: The plug may not seal perfectly if your chute has debris or rust buildup. Clean the chute area before installing.
• Performance: Works best with high-lift blades (check your mower’s blade type). Dull blades will produce poor mulching results even with the plug.

Should You Buy It

If you own one of the listed Ex-Mark 30-inch Timemaster or Turfmaster models and want cleaner mulching without side-discharge clumping, this OEM plug is a reliable, easy upgrade. Skip it if you prefer bagging or side-discharge only, or if your deck isn’t on the fitment list.
