MaxPower 561156XB 3 Commercial Mulching Blade Set for 54" Hustler mowers, Replaces OEM Numbers 797704, 797712, 438-0001-00

What It Is

The MaxPower 561156XB is a set of three commercial-grade mulching blades designed specifically for 54-inch Hustler mower decks. These blades lift and recut clippings into fine particles to return nutrients to the lawn, ideal for frequent mowing on large properties.

Fitment & Compatibility

• Deck size: Only fits 54" Hustler mower decks. Measure your deck width before ordering.
• OEM cross-reference: Replaces Hustler OEM numbers 797704, 797712, and 438-0001-00. If your current blades match any of these numbers, these are direct replacements.
• Bolt pattern: These use a 5-point star center hole. Verify your spindle bolt pattern matches—most Hustler commercial decks do, but check your spindle for star or hex shape.
• Length & thickness: Each blade is approximately 20.5" long and 0.203" thick. Measure your old blade length to confirm. Thickness is slightly heavier than standard residential blades, so ensure your spindle can handle the added weight.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket wrench and torque wrench. Tighten bolts to 70–80 ft-lbs (check your mower manual). Left-hand threads are common on some Hustler spindles—verify rotation direction before tightening.
• Balance: These blades come pre-balanced, but always check with a blade balancer after installation to avoid vibration. Unbalanced blades can damage spindles.
• Mulching performance: The high-lift design works best with sharp blades and dry grass. Wet or tall grass will clog and reduce cut quality. Consider switching to high-lift bagging blades if you mow infrequently or in dense growth.
• Durability: Heat-treated steel holds an edge longer than standard blades, but hitting rocks or roots will still chip or bend them. Inspect after each use.

Should You Buy It

If you own a 54" Hustler commercial mower and want a rugged, OEM-compatible mulching blade set that improves clippings recycling and reduces bagging frequency, this is a solid value at $45.77. It’s not for residential decks or other brands—double-check fitment first. For heavy-duty commercial use, these blades are a reliable upgrade over basic steel sets.
