8TEN LawnRAZOR Mower Blade Set for Murray Old Style Universal 38 inch Deck Cut 91742 91742HT (High-Lift)

What It Is

The 8TEN LawnRAZOR Mower Blade Set (91742/91742HT) is a high-lift replacement blade set designed for Murray “Old Style” universal fitment on 38-inch cutting decks. These blades are engineered for improved grass lift and discharge, making them ideal for bagging or side-discharge mowing on residential lawns.

Fitment & Compatibility

Before buying, verify three things:

1. Deck size: This set fits only 38-inch cutting decks. Measure your deck width to confirm.
2. Blade measurements: Each blade is 20.5 inches long, 2.5 inches wide, with a 5-point star center hole (1 inch diameter) and 0.25-inch thickness. Check your old blade’s length and hole shape.
3. Model fitment: Designed for Murray “Old Style” decks (pre-2000s) and universal fit for many Murray, Noma, and Yard King models. Confirm your mower’s model number against 8TEN’s compatibility list. Not for newer Murray or other brand decks without verifying hole pattern.

Key Things to Know

• High-lift design: Provides strong suction for bagging but may cause clumping in wet grass or on uneven terrain.
• Installation: Moderate difficulty; you’ll need a socket wrench and blade removal tool. Torque bolts to 70–90 ft-lbs.
• Sharpness: Out of the box, edges are sharp but not razor-fine. Some users prefer to touch up with a file before first use.
• Durability: Heat-treated steel holds up well against sticks and rocks, but high-lift blades wear faster than standard lift equivalents.

Should You Buy It

If you own a Murray (or compatible) 38-inch deck mower and need a reliable, affordable high-lift blade set for bagging or side-discharge, this is a solid choice. The 4.5-star rating and 96 reviews back its performance. Skip it if you mulch frequently—standard lift blades work better for that.
