What It Is

The GY20569 M115496 High Lift Toothed Mower Blades are a 3-pack of aftermarket replacement blades designed for 54-inch John Deere and Scotts lawn tractor decks. Their high-lift, toothed design improves grass clipping lift and discharge, making them ideal for thick or damp grass where standard blades might leave clumps.

Fitment & Compatibility

• Deck size: Only fits 54-inch decks. Measure your deck width before buying.
• Compatible models: John Deere 325, 335, S2554, GT2554, 2254HV, 2354HV, G100, and Scotts 54-inch decks. Check your model number on the deck or manual.
• OEM cross-references: Replaces John Deere M113518, M115496, and M135590. Not an OEM part—verify blade hole pattern (center hole size and offset) matches your spindle.
• Measurements: Blade length is approximately 18.5 inches, with a 7/16-inch center hole. Confirm spindle bolt size (typically 5/8-inch or 7/16-inch) and blade thickness (about 0.25 inches) to avoid fit issues.

Key Things to Know

• Quality: Rated 4.2/5 stars from 27 reviews—generally good for the price, but some users report balance issues out of the box. Check balance before installing.
• Installation difficulty: Moderate. Requires lifting the mower, removing the deck, and using a torque wrench (specs: 70-90 ft-lbs for spindle bolts). Use thread locker on bolts.
• Common gotchas: High-lift blades consume more engine power—may bog down in very tall grass. Ensure your deck has adequate discharge clearance (not for mulching or bagging without a high-lift kit).
• Wear: Toothed edge wears faster than standard blades; inspect monthly for dullness or damage.

Should You Buy It

If you have a compatible 54-inch John Deere or Scotts deck and need better lift in heavy grass without upgrading to OEM, this 3-pack is a cost-effective choice. Avoid it if your deck is smaller than 54 inches or you need mulching blades—these are strictly for side-discharge use.
