This is a three-blade mulching set designed for many 46-inch cut Murray lawn tractors. It replaces OEM part numbers 56631E701 and 656631, and its primary use is to finely chop grass clippings and return them to the lawn as natural fertilizer.
Fitment & Compatibility
Before buying, confirm your mower’s cutting deck is exactly 46 inches (measure from blade tip to blade tip). This set fits most Murray 46-inch models, but check your owner’s manual or existing blade part number to ensure it matches OEM 56631E701 or 656631. The blades measure 16.5 inches long with a 1-inch center hole and a 0.5-inch offset, and they use a 5/16-inch bolt. If your Murray deck uses a different spindle pattern or bolt size, this set won’t work. Also, verify your deck has three spindles—this is a three-blade set, not a two-blade design.
Key Things to Know
- Build quality: Blades are made of heat-treated steel and come pre-sharpened, but they may require light honing for optimal cut performance out of the box.
- Installation difficulty: Easy—remove the old blades, install these with the sharp edge facing the direction of rotation, and torque bolts to 50–60 ft-lbs. Use a blade removal tool to avoid slipping.
- Mulching performance: The curved design and extra lift create a finer clip than standard blades, but they work best with dry grass. Wet or tall grass may still leave clumps.
- Common gotcha: Some users report the blades are slightly thinner than OEM, so they may wear faster on rocky or sandy soil. Check deck clearance to avoid blade strike.
Should You Buy It
If you own a Murray 46-inch tractor and want a budget-friendly mulching upgrade that beats standard discharge blades for lawn health, this set is a solid choice. It’s not the most durable option for heavy-duty or commercial use, but for typical residential mowing, the price and performance are hard to beat. Just double-check your deck size and spindle count first.
