One 942-0741A Mulching Blade Fits Troybilt Push Mowers with 21" Deck

What It Is

The 942-0741A is an aftermarket mulching blade designed for Troybilt push mowers with a 21-inch cutting deck. It replaces the stock blade to chop grass clippings into fine particles that decompose quickly, eliminating the need for bagging.

Fitment & Compatibility

• Deck size: Only fits 21-inch cutting decks. Measure your deck width if unsure.
• Model fit: Compatible with most Troybilt push mowers (e.g., TB110, TB120, TB130, TB200, TB230) using a 3.5-inch center hole and a 1-inch diameter arbor hole. Verify your mower’s blade mount type—this blade uses a single center bolt.
• OEM reference: Replaces Troybilt OEM part 942-0741A. Aftermarket, not OEM.
• Measurements: Blade length must be exactly 21 inches (center to tip). Check thickness (usually 0.125 inches) and ensure it clears the deck housing.
• Check your owner’s manual or existing blade’s part number to confirm compatibility before purchasing.

Key Things to Know

• Quality: Customers report it’s sharp out of the box and durable for typical residential use. Aftermarket, but consistently rated 4.6/5.
• Installation: Moderate difficulty—requires removing the center bolt (likely 5/8-inch socket), cleaning the spindle, and torquing to 40–50 ft-lbs. Use thread locker if not pre-applied.
• Common gotcha: This is a mulching blade only—it lacks a lift wing for bagging or side discharge. If you switch between modes, you’ll need a separate blade.
• Fitment nuance: Some Troybilt models with a 21-inch deck use a different arbor size (e.g., 7/8-inch). Double-check your spindle’s shaft diameter; this blade fits 1-inch arbors.

Should You Buy It

Buy this if you have a Troybilt push mower with a 21-inch deck, want clean mulching for a healthier lawn, and are comfortable with a simple blade swap. Avoid if your mower uses a different arbor size or you need a combo blade for bagging/discharge. For the price, it’s a solid upgrade over a worn OEM blade.
