3PK 391-614 Mulching Blade Gator G6 16-1/2" Replaces 1759055YP

What It Is

This is a 16-1/2-inch mulching blade set (3-pack) with a Gator G6 design, engineered to shred grass clippings into fine particles for natural lawn feeding. It replaces OEM part 1759055YP and is intended for residential zero-turn or riding mowers with a 54-inch or similar deck that uses three blades.

Fitment & Compatibility

Before buying, confirm your mower deck requires three 16-1/2-inch blades. Measure your existing blade length (from tip to center hole) and ensure it matches exactly. Check the center hole size (typically 1-inch) and the blade thickness (usually 0.203-inch). This blade replaces OEM 1759055YP, used on select Husqvarna, Craftsman, and Poulan Pro models with 54-inch decks. Verify your mower’s model number against the OEM part number—this is not universal for all 54-inch decks. Avoid assuming fitment based on brand alone; always cross-reference your deck model.

Key Things to Buy

• Quality: Gator G6 blades use hardened steel with a serrated edge for superior mulching. They are thicker than many OEM blades, which can reduce lift if your deck isn’t designed for them.
• Installation: Easy if you have a socket wrench and blade removal tool. Torque to 70–90 ft-lbs. Sharp edges—wear gloves.
• Common gotchas: The G6 design may not fit decks with low-clearance spindle housings. Check for blade-to-deck interference before tightening. Also, these blades are for mulching only; they won’t bag or discharge well.
• Price: $104.89 for three blades is mid-range; comparable OEM sets run $90–$120. Two reviews mean limited feedback—buy from a reputable seller with return policy.

Should You Buy It

Buy this if you have a compatible 54-inch deck (e.g., Husqvarna, Craftsman, Poulan Pro) and prioritize fine mulching over bagging or side discharge. The Gator G6 design is proven for clumping reduction and even lawn feeding. Skip it if your deck is not listed for OEM 1759055YP or if you need a universal fit—measure twice first.
