2PK Oregon 596-370 G5 Gator Blade for 46" Husqvarna YTH22V46

What It Is

The 2PK Oregon 596-370 G5 Gator Blade is a set of two aftermarket mulching blades designed for 46-inch cutting decks, specifically engineered to lift, cut, and recirculate grass clippings into fine mulch. They are ideal for homeowners with Husqvarna YTH22V46 (and similar 46-inch deck tractors) who want a cleaner cut and reduced bagging.

Fitment & Compatibility

Before buying, check three things:

• Deck size: These blades are for 46-inch decks only. Measure your deck’s cutting width (blade tip to blade tip) to confirm.
• Model fit: Designed for Husqvarna YTH22V46, but also fit many other 46-inch decks from Husqvarna, Poulan Pro, Craftsman, and AYP/MTD. Cross-reference your OEM part number: commonly replaces 532 42 76-37, 532 42 76-38, and 532 42 76-39.
• Blade dimensions: Each blade is 20.5 inches long, 2.25 inches wide, with a 1-inch diameter center hole and a 7-point star drive. Verify your spindle’s drive pattern—these are not for standard round-hole spindles.

Double-check your mower’s model number (e.g., YTH22V46) and deck part number (usually stamped on the deck) before ordering.

Key Things to Know

• Mulching performance: The G5 “Gator” design uses serrated edges and deep air lifts to mulch leaves and grass into fine particles. Expect less clumping and faster decomposition than standard blades.
• Installation difficulty: Easy swap with basic tools (socket wrench, torque wrench). Use a blade removal tool or wedge a block of wood to prevent spinning. Torque to 70–90 ft-lbs.
• Durability: Oregon uses heat-treated steel. These blades last 1–2 seasons under normal use, but hitting rocks or roots can dull them quickly. Sharpen with a file or grinder.
• Common gotcha: They are not universal—will not fit 42-inch or 54-inch decks. Also, the star drive pattern is less common; verify your spindle matches before buying.

Should You Buy It

Buy this set if you own a 46-inch Husqvarna (or compatible AYP/MTD tractor), want superior mulching without switching to a bagger, and are comfortable with basic blade replacement. It’s a strong upgrade over OEM blades for a reasonable price, especially if you mow frequently and want a finer lawn finish.
