ILONPA 48" 3-in-1 Toothed Mulching Blades for 48-inch Zero-Turn Decks — Black, Hardened Steel, Raised Air-Lift

These ILONPA 48-inch 3-in-1 mulching toothed blades replace OEM part numbers for Bad Boy, Scag, Hustler and other zero-turn and walk-behind decks to restore cutting performance and improve clippings dispersion.

When your mower’s cut quality slips or mulching efficiency drops, installing a robust set of replacement blades gets decks back to factory-style performance. This ILONPA blade set is engineered to fit a wide range of 48" decks (and some 32", 50" and 52" decks) and matches multiple OEM part numbers so you can swap blades without modifying spindles. Made from hardened steel with a raised air-lift profile and a toothed mulching edge, these blades help maintain an even cut, reduce scalping, and break clippings finer for faster decomposition.

Which machines and OEM numbers are these blades compatible with?

These blades are designed to be a direct fit for many popular zero-turn and stand-on decks, replacing several OEM numbers across brands. Check your deck size and center-hole dimensions to confirm fit before ordering.

• Bad Boy: fits ZT Elite, Maverick, Maverick HD, CZT, Revolt and MZ/Magnum 48 decks (OEM 038-5000-00, 038-5350-00, 038-5350-0050).
• Hustler: compatible with Fastrak and Raptor SD 48 decks (OEM 795757, 795757X, 796623, 796631).
• Scag: fits Tiger Cub, Cheetah and Freedom Z models and other listed SCZ/SFZ/STC variants (OEM 481706, 482461, 482877, 483316).
• Also fits certain 32", 50" and 52" applications that use the same center-hole and lift profile.

How do these blades affect cut quality and mulching?

The 3-in-1 toothed profile combines side discharge, bagging and mulching capabilities to keep your options open while improving mulch processing. The raised air-lift and tooth geometry promote better grass circulation under the deck, producing a more uniform finish and finer clippings.

• Toothed cutting edge chops clippings finer for faster breakdown.
• 1" air lift improves grass lift and reduces uneven cutting or scalping.
• Balanced design maintains even rotation to minimize vibration and spindle wear.
• Works for mulch, discharge, or bagging depending on setup and RPM.

What are the precise dimensions and mounting details?

Measure your blade against these specifications to ensure compatibility—matching size and center-hole type is crucial for safe operation. These blades use a standard circular center hole and a common thickness that suits many commercial and residential spindles.

• Overall blade length: 16-3/8" (416 mm).
• Cutting width: 2-1/2" (63.5 mm); thickness: 1/5" (5 mm).
• Center hole: circular, 5/8" (16 mm); air lift: 1" (25 mm).
• Type: 3-in-1 mulching toothed blade compatible with 48" decks (also listed for select 32", 50", 52").

How should I install and maintain these replacement blades?

Installation is straightforward for anyone familiar with blade swaps; use the correct torque and anti-seize if recommended by your mower manufacturer. Regular sharpening, proper torque, and inspection for damage will extend blade life and preserve cut quality.

• Tighten blade hardware to your mower OEM torque spec and re-check after first hour of use.
• Keep blades sharp and balanced; replace if bent or cracked.
• Inspect spindle and mounting hardware while blades are off to avoid collateral wear.
• Use appropriate PPE and secure mower before servicing blades.

Who is this for: These ILONPA 48" mulching blades are aimed at homeowners and commercial operators who own compatible Bad Boy, Scag, Hustler, Snapper or similar zero-turn and stand-on mowers and want an affordable, OEM-replacement-quality blade set. If you need reliable mulching performance, improved clipping dispersion, and a direct-fit replacement that covers multiple OEM numbers, this set is built for routine maintenance and season refreshes.
