Oregon 6PK 91-620 Lawn Mower Blades Compatible with Scag 32" 48110, 481706, 482877 A48110, 48" Tiger Cub Freedom Z

What It Is

The Oregon 6PK 91-620 is a set of six aftermarket mulching blades designed for 32" and 48" Scag mowers, specifically the Tiger Cub and Freedom Z models. These blades are intended for residential or light commercial use, offering a cost-effective alternative to OEM Scag blades for mulching grass clippings.

Fitment & Compatibility

Before buying, verify your mower deck size and model. This set fits Scag 32" decks (part numbers 48110, 481706, 482877, A48110) and 48" Tiger Cub/Freedom Z decks. Measure your blade length—these are 16.5" long with a 5-point star center hole and 2.5" diameter. They are not compatible with 36", 52", or 61" Scag decks. Confirm your Scag model year; older models may use different blade patterns. Aftermarket blades like these may require minor balancing or filing to match OEM fit.

Key Things to Know

• Quality vs OEM: Oregon blades are durable for residential use but may not last as long as Scag OEM blades in heavy commercial mowing (daily use on rough terrain).
• Installation: Easy DIY job with a socket wrench and blade removal tool. Torque to 70-90 ft-lbs. Ensure blades spin freely after mounting.
• Common Gotcha: These are mulching blades, not lift blades—expect finer clippings but less bagging efficiency. Check your deck’s blade orientation; some Scag decks require specific offset.
• Balance Check: Blades may arrive slightly out of balance; use a blade balancer (~$10) to prevent vibration and spindle wear.

Should You Buy It

Buy this set if you own a compatible 32" or 48" Scag mower and want affordable mulching blades for regular residential lawn care. It’s a solid value for the price, but skip it if you need OEM-grade durability for daily commercial use or if your deck requires lift blades for bagging.
