6PK Oregon 92-029 Blade for 48" Exmark 103-6381 103-6391 103-6396 103-6401 Toro 109-6872

What It Is

This is a 6-pack of Oregon 92-029 replacement blades designed for 48-inch Exmark and Toro zero-turn mowers. They’re aftermarket equivalents for OEM part numbers 103-6381, 103-6391, 103-6396, 103-6401 (Exmark), and 109-6872 (Toro), intended for commercial or residential cutting on medium-to-large lawns.

Fitment & Compatibility

Before buying, confirm your deck is exactly 48 inches—these blades won’t fit 42” or 52” decks. Check your mower model against the OEM numbers listed: Exmark Lazer Z, Lazer Z X-Series, or Toro Z Master models with those specific blade part numbers. Measure your current blade length (should be 18.5 inches long, 2.25 inches wide, with a 5/8-inch center hole and 0.25-inch pin holes). Oregon blades are aftermarket, so if you need OEM-only for warranty or dealer requirements, stick with Exmark/Toro originals.

Key Things to Know

• Quality: Oregon blades are heat-treated and hardened, offering good durability for residential and light commercial use, but may not match OEM steel in heavy commercial conditions.
• Installation difficulty: Easy—just remove the old blade, clean the spindle, and torque to 70-80 ft-lbs. Use a blade removal tool and block the blade to prevent spinning.
• Common gotcha: These blades have a “sail” lift design that improves bagging and mulching but can create more noise and vibration if not balanced. Always balance after installation.
• Pack value: Buying a 6-pack is cost-effective if you need multiple replacements, but if you only need one or two, single packs may be cheaper.

Should You Buy It

Buy this if you own a 48-inch Exmark or Toro zero-turn and want reliable aftermarket blades at a lower per-blade cost than OEM. It’s ideal for homeowners or light commercial users who change blades regularly and don’t require premium OEM steel. Skip it if you need exact OEM fit for warranty, or if your deck is a different size.
