MaxPower's 561145XB 3 Commercial Mulching Blade Set for 52" Hustler Mowers, Replaces OEM Numbers 30227-52X, 785436, 51-2220

What It Is

This is a set of three commercial-grade mulching blades designed for 52-inch cutting decks on Hustler mowers. It replaces OEM part numbers 30227-52X, 785436, and 51-2220, and is intended for heavy-duty mulching—chopping clippings into fine bits to leave on the lawn.

Fitment & Compatibility

Before buying, confirm your deck is exactly 52 inches wide and that your mower is a Hustler model (e.g., Super Z, FasTrak, Z). These blades are aftermarket replacements for the listed OEM numbers, so cross-check your current blade’s part number against those. Measure the blade length (roughly 18 inches), center hole diameter (should be 1 inch), and thickness (about 0.25 inch). Also verify the blade’s cutting edge orientation—mulching blades have a distinct curved shape. If your mower uses a different mounting system (e.g., oval hole), these won’t fit.

Key Things to Know

• Quality: MaxPower’s 561145XB blades are heat-treated steel with a protective coating, matching OEM durability for commercial use. They’re thicker than standard blades, reducing bending.
• Installation: Straightforward—remove the old blade, install with the curve facing up toward the deck. Torque the bolt to 70–90 ft-lbs. Use a blade removal tool and wear gloves.
• Gotcha: These are mulching blades, not for bagging or side-discharge. If you switch between modes, you’ll need a separate set of standard blades.
• Performance: Expect finer clippings but slightly more engine load. Keep blades sharp for best results—dull mulching blades tear grass.

Should You Buy It

If you own a 52-inch Hustler mower and want commercial-grade mulching performance without paying OEM prices, this set is a solid buy. The high rating and low price make it a no-brainer for frequent mulching, but skip it if you need bagging or standard lift blades.
