Murray 7103288YP Lawn Mower 22-in Deck 3-in-1 Blade Genuine Original Equipment Manufacturer (OEM) Part

What It Is

This Murray 7103288YP is a genuine OEM 22-inch 3-in-1 blade designed for mulching, bagging, and side-discharge mowing. It fits select Murray and Noma walk-behind mowers with a 22-inch cutting deck.

Fitment & Compatibility

Before buying, confirm your mower has a 22-inch deck (measure from blade tip to blade tip). This OEM part is direct-fit for Murray models like 42577x92, 42579x92, and 42587x92, plus some Noma units. Check your model number under the seat or on the deck. Aftermarket blades may vary in thickness or hole size – this blade uses a 1-inch center hole and two offset pins for anti-scalp hubs. Measure your old blade’s center hole and pin spacing (roughly 2.5 inches apart) to match. Do not use on 21-inch or 20-inch decks.

Key Things to Know

• Quality: OEM steel holds an edge longer than cheap aftermarket blades, but still check for bends or cracks before installing.
• Installation difficulty: Easy with a socket wrench and blade removal tool. Torque the center bolt to 30-40 ft-lbs. Always disconnect the spark plug first.
• Common gotcha: This blade is not universal – the offset pin holes are specific to Murray’s quick-change hub system. If your deck uses a single bolt and washer, this won’t fit.
• Sharpening: Can be sharpened 2-3 times, but replace if nicked or bent.

Should You Buy It

Yes, if you own a compatible Murray/Noma 22-inch mower and want a reliable, direct-fit blade that won’t require adapter kits or drilling. The OEM build ensures proper balance and cut quality, making it a solid value for $33.38. Skip it if you need a universal blade or have a different brand.
