Oregon 6PK 596-308 G5 Gator Blades for 48" Scag 48110, 48184, 482461, 482877

What It Is

This is a set of three Oregon G5 Gator mulching blades (model 6PK 596-308) designed for 48-inch Scag commercial zero-turn mowers. They replace OEM part numbers 48110, 48184, 482461, and 482877, and are intended for high-volume mulching, bagging, or side-discharge use on heavy-duty turf.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 48 inches—these blades only fit Scag decks with a 3-blade spindle pattern. Measure blade length (should be 18.5 inches), center hole diameter (5/8 inch), and spindle pin count (typically 2-pin). Cross-check your Scag model against the OEM numbers listed: 48110, 48184, 482461, or 482877. If your Scag uses a different OEM part (e.g., 48178 or 482920), these will not fit. Aftermarket blades like these are direct replacements but may require minor balancing—check with a blade balancer before installing.

Key Things to Know

• Quality & Durability: G5 Gator blades are heat-treated and have a hardened steel edge, lasting longer than standard OEM blades under heavy use. They feature a patented “Gator” notch design for finer mulching.
• Installation Difficulty: Moderate. You’ll need a socket wrench and torque wrench (recommended torque: 70–90 ft-lbs). Lift the deck safely or remove the blades with the mower on its side. Always disconnect the spark plug first.
• Common Gotcha: These blades are thicker than some OEM versions, which can cause clearance issues on decks with tight spindle-to-blade housing gaps. Check that the blade tips don’t contact the deck shell before tightening. Also, they are not reversible—sharpen only the cutting edge, not the mulching notch.
• Performance Note: They mulch aggressively but may leave clumps in wet grass. Use at full throttle and keep blades sharp for best results.

Should You Buy It

Buy this if you have a 48-inch Scag with the listed OEM part numbers and want a high-quality aftermarket blade that excels at mulching and lasts longer than standard steel. It’s ideal for commercial operators or large lawns, but skip it if your Scag uses different OEM blades or if your deck has known clearance issues with thicker aftermarket sets.
