8TEN LawnRAZOR Mower Blade Set for John Deere Scotts 325 F510 GT242 GX345 48 inch Decks M113517 M115495 (Toothed)

What It Is

This is a set of three toothed (mulching) blades designed for 48-inch mower decks on select John Deere and Scotts lawn tractors. They replace OEM part numbers M113517 and M115495, intended for cutting grass and mulching clippings.

Fitment & Compatibility

Before buying, confirm your mower has a 48-inch deck and matches one of these models: John Deere 325, F510, GT242, GX345, or Scotts 325. Measure your existing blade length (should be ~18 inches) and center hole size (typically 1 inch). These are aftermarket replacements for OEM M113517 and M115495—check your owner’s manual or current blade part number. Not compatible with 42-inch or 54-inch decks, or non-listed models.

Key Things to Know

• Mulching design: The toothed edge helps chop clippings fine, but may not work well in wet grass or heavy debris.
• Installation: Moderate difficulty—requires a socket wrench and blade removal tool. Torque to manufacturer spec (usually 70–90 ft-lbs). Always use thread-locker and new bolts if possible.
• Balance: Inspect each blade for balance before mounting; aftermarket sets can sometimes be slightly off. An unbalanced blade causes vibration and deck damage.
• Durability: Steel construction holds up for a full season of residential use, but avoid hitting rocks or roots—teeth can dull or chip faster than standard blades.

Should You Buy It

If you own a listed John Deere or Scotts with a 48-inch deck and want a budget-friendly mulching upgrade, this set is a solid choice. It’s best for residential mowing on well-kept lawns. Avoid if you need a standard lift blade for bagging or side-discharge, or if your deck model isn’t confirmed compatible.
