A ABIGAIL 3-Pack 50" Replacement Mower Blades for 50" Decks — 2-in-1 Mulching & Side-Discharge, 65Mn Steel

These are three A ABIGAIL 2-in-1 replacement mower blades designed for 50" cut decks, built from heat-treated 65Mn steel with a rust-resistant coating for dependable mulching and side-discharge performance.

If your lawn tractor uses a 50-inch deck and the OEM blade number matches the ones listed, these 17-1/4" A ABIGAIL blades are a direct-fit, heavy-duty option. Forged manganese steel and a protective finish help resist wear from roots and rocks, and the 2-in-1 cutting profile supports both mulching and traditional discharge. We include exact measurements and a reminder to verify your original blade part number before ordering so you get the right replacement the first time.

How will these blades affect mowing performance?

These A ABIGAIL blades sharpen clippings and circulate grass efficiently across a 50" deck, improving cut consistency and mulching when compared to worn factory blades. The 2-in-1 edge geometry was shaped to create lift for effective side discharge while also finely chopping clippings for mulching setups.

• Precise 17-1/4" length and 2-1/2" width to match 50" decks.
• 2-in-1 design supports both mulching and side-discharge.
• Forged 65Mn manganese steel for improved edge-holding.
• Powder-coated finish reduces surface rust and debris buildup.

Will these blades fit my Cub Cadet, Troy-Bilt, or MTD mower?

The blades replace several OEM part numbers (including 942-05052A and 742-05052A) and are compatible with many 50" models from Cub Cadet, Troy-Bilt, MTD, Columbia and others. Because mower fitments can vary by year and submodel, confirm your original blade number, deck size, and center hole type before purchase.

What are the exact dimensions and mounting details?

Each blade measures 17-1/4 inches long and 2-1/2 inches wide, sized for decks that specify 50" cut blades laid out in pairs or threes. The center hole uses a six-point star pattern; measure center-to-center of the outside holes to confirm the 3" spacing matches your spindle pattern.

• Length: 17-1/4" (per blade), Width: 2-1/2".
• Center hole: six-point star configuration.
• Center-to-center outside hole spacing: 3" for correct alignment.
• Sold as a set of three replacement blades for most 50" decks.

How should I choose and maintain these blades?

Select blades only after confirming your mower’s deck size and OEM replacement number — do not rely solely on compatible model lists. For best results, periodically inspect for nicks and balance, sharpen as necessary, and keep the coating intact to extend service life.

• Verify OEM part number and deck size before ordering.
• Inspect for damage and rebalance after any sharpening.
• Replace in matched sets to maintain deck balance and cut quality.
• Contact customer service for troubleshooting, replacement, or refund if needed.
