8TEN LawnRAZOR Mower Blade Set for Murray Lawn Tractor 46901X92A 46 inch Decks 92117E701 92117E701MA (High Lift)

What It Is

This is a set of three high-lift mower blades designed for 46-inch cutting decks on Murray lawn tractors, specifically replacing OEM part numbers 46901X92A, 92117E701, and 92117E701MA. High-lift blades create stronger upward airflow, improving grass clipping discharge and bagging performance, especially for thick or damp grass.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Fits only 46-inch wide decks. Measure your deck if unsure.
• Model/brand: Designed for Murray lawn tractors with 46-inch decks. Also compatible with some MTD, Yard Machines, and Craftsman models using the same OEM numbers, but cross-check your model number with the listed OEM part numbers.
• Measurements: Each blade is approximately 20.5 inches long, 2.25 inches wide, with a 1-inch center hole and 7-point star center. Check your existing blade’s length, center hole shape, and width to confirm fit. High-lift blades may not fit decks with limited clearance under the spindle or low-hanging chutes.

Key Things to Know

• Installation difficulty: Moderate. Requires jacking up the tractor, removing the deck or accessing blades from underneath. Use a blade removal tool and torque to 70-80 ft-lbs. Mark blade orientation before removal.
• Quality: 8TEN blades are aftermarket but well-reviewed for durability and sharpness out of the box. Some users report slight balancing issues; check with a blade balancer before installing.
• Common gotchas: High-lift blades increase engine load and may cause belt slipping on older or underpowered tractors. They also throw clippings farther—avoid using near gravel or flower beds.
• Mulching note: These are not mulching blades. They are designed for side discharge or bagging. If you need mulching, look for a low-lift or mulching-specific blade set.

Should You Buy It

Buy this set if you have a Murray or compatible 46-inch lawn tractor, need to replace worn or bent blades, and want better bagging or discharge performance in heavy grass. Avoid if your deck has limited clearance, your tractor is underpowered, or you primarily mulch. For the price, it’s a solid aftermarket upgrade for most users.
