Oregon 96-346 Grasshopper Gator Mulcher 3-In-1 Hi Lift Replacement Lawn Mower Blade 21-Inch,Black

What It Is

The Oregon 96-346 is a 21-inch, 3-in-1 hi-lift mulching blade designed for EGO cordless walk-behind mowers. It replaces the stock blade to improve mulching, bagging, and side-discharge performance by generating more lift and finer clippings.

Fitment & Compatibility

Before buying, verify your mower has a 21-inch cutting deck—this blade is standard on most EGO 21-inch models (e.g., LM2100, LM2101, LM2102SP, LM2135SP). Check the blade’s center hole (must be a star-shaped 5-point pattern, common on EGOs) and overall length (21 inches from tip to tip). This is an aftermarket replacement for OEM part EGA2100-0000 or similar. If your mower uses a different blade-mounting system (e.g., keyed or oval hole), it won’t fit. Measure your current blade’s width and thickness—Oregon’s is 2.25 inches wide and 0.180 inches thick—to confirm deck clearance.

Key Things to Know

• Lift difference: Hi-lift blades increase suction for better bagging but may reduce runtime slightly on battery mowers due to higher drag.
• Installation: Use a torque wrench to tighten the center bolt to 35-40 ft-lbs (spec per EGO manual). Over-tightening can strip the star mount.
• Mulching vs. bagging: The “3-in-1” design works for all three modes, but if you primarily side-discharge, a standard lift blade may be quieter.
• Sharpness: Oregon blades come pre-sharpened but may need a light touch-up after a few uses for optimal cut quality.

Should You Buy It

Yes, if you own a 21-inch EGO mower and want better mulching and bagging performance than the stock blade delivers. It’s a solid upgrade for thicker grass or fall leaf cleanup, but skip it if you only side-discharge or prefer OEM simplicity.
