Oregon 91-620 Blade for 48" Scag 48110 481706 482877 Lesco 21871 50111 Hustler 601123

What It Is

The Oregon 91-620 is a replacement mulching blade designed for 48-inch zero-turn mowers, specifically compatible with Scag, Lesco, and Hustler models. It’s intended for homeowners or light commercial use, providing a clean cut and fine clippings for mulching.

Fitment & Compatibility

Before buying, check these specifics:

• Deck size: Fits 48-inch cutting decks only. Measure your deck width to confirm.
• Model fit: Directly replaces OEM blades for Scag (part #48110, 481706, 482877), Lesco (21871, 50111), and Hustler (601123). Also fits some Gravely and Bob-Cat models with the same spindle pattern.
• Measurements: Blade length is 18.5 inches, center hole diameter is 5/8 inch, and thickness is 0.203 inches. Verify these against your current blade.
• OEM vs aftermarket: This is a high-quality aftermarket blade, not OEM. It’s often cheaper than Scag or Lesco brand blades but may have slight weight or balance differences. Check your spindle clearance—some older decks may need a spacer or washer.

Key Things to Know

• Quality: Oregon is a reputable brand, but the 3.8-star rating (6 reviews) suggests mixed feedback. Some users report premature dulling or chipping on rocky lawns.
• Installation: Easy with basic tools—a wrench and a blade removal tool. Torque bolts to 70-90 ft-lbs. Use a blade balancer to avoid vibration.
• Common gotcha: These are mulching blades (curved, with more lift). If you prefer bagging or side-discharge, they may not perform as well—stick with OEM high-lift blades for those tasks.
• Price: At $108.99, it’s a mid-range option. OEM blades for these decks often cost $120-$150 each, so it’s a value pick if mulching is your priority.

Should You Buy It

Buy this if you need a reliable mulching blade for a 48-inch Scag, Lesco, or Hustler mower and want to save money over OEM parts. Skip it if you primarily bag or discharge clippings, or if your lawn has heavy debris that could chip thinner blades. For light residential use, it’s a solid choice; for heavy commercial use, consider OEM for longer edge life.
