3PK Oregon 99-132 High Lift Mower Blades Replacement for Simplicity Snapper 1737228 1737228A 1737228AYP 1737228BM 1737228BZ 16-1/8"

What It Is

This is a three-pack of Oregon 99-132 high-lift mower blades, designed to replace OEM Simplicity/Snapper part numbers 1737228, 1737228A, 1737228AYP, 1737228BM, and 1737228BZ. High-lift blades create stronger upward airflow, improving grass clipping discharge and bagging performance, especially in thick or wet grass.

Fitment & Compatibility

Before buying, verify three things:

1. Deck cut width: These blades are 16-1/8" long, so they fit mower decks designed for that specific blade length—typically 38" to 52" decks with multiple blades.
2. Brand and model: Direct fit for Simplicity and Snapper models that use the OEM 1737228 series. Not universal—check your owner’s manual or current blade part number.
3. Center hole and drive: Measure your existing blade’s center hole diameter (usually 1" or 7/8") and ensure it matches. Also confirm the blade drive type (star, oval, or round) matches your spindle.

Key Things to Know

• Quality: Oregon is a reputable aftermarket brand; these blades are made from heat-treated steel and are typically as durable as OEM, though some users report slightly faster wear in sandy soil.
• Installation: Relatively easy if you’re comfortable removing the deck or accessing the spindle. Use a torque wrench—recommended torque is 50–60 ft-lbs for the center bolt. Always install with the lift wings facing up (toward the deck).
• Common gotchas: High-lift blades increase engine load slightly; you may notice a small drop in mowing speed or fuel efficiency. They also throw debris more aggressively—keep bystanders clear.
• Tip: Replace all blades at once for balanced cutting and vibration. Worn or bent blades can damage the spindle or deck.

Should You Buy It

If you have a Simplicity or Snapper mower that takes 16-1/8" blades and you want stronger bagging performance, this is a solid, cost-effective replacement. It’s not for standard lift needs or decks requiring a different blade length—stick with OEM or standard-lift blades for mulching or side discharge in dry conditions.
