3pk 90-698 Gator G3 Lawn Mower Blade Compatible with Snapper, Simplicity 1708229, 1708229A, 1716697, 1716697A

What It Is

A three-pack of 90-698 Gator G3 mulching blades designed for Snapper and Simplicity lawn tractors. These aftermarket blades replace OEM part numbers 1708229, 1708229A, 1716697, and 1716697A, and are intended for mowing decks that require a high-lift, mulching blade for fine grass clipping dispersal.

Fitment & Compatibility

Before buying, verify your mower deck size and blade measurements. These blades are 21 inches long, with a 1-inch center hole and a 7/8-inch diameter center hole (check your spindle hub). They fit most Snapper and Simplicity models using the OEM part numbers listed, but not all—cross-reference your model number with the manufacturer’s compatibility chart. Measure your existing blade length, hole diameter, and thickness (typically 0.25 inches). Avoid assuming fit for older or non-standard decks; some Snapper/Simplicity decks use a different blade pattern or offset.

Key Things to Know

• Quality: Gator G3 blades are known for durable steel and a mulching design with curved wings that create vacuum lift. They’re a solid aftermarket choice, but may not be as precisely balanced as OEM.
• Installation difficulty: Moderate. You’ll need a torque wrench (recommended 70-90 ft-lbs) and blade removal tool. Always use anti-seize on spindle bolts to prevent seizing.
• Common gotcha: The 7/8-inch center hole may not fit all Snapper/Simplicity spindles—some use a 1-inch or 5/8-inch hole. Double-check your spindle’s pilot diameter. Also, these are not universal; they won’t fit decks under 42 inches wide.
• Pack size: Three blades typically cover one 42-54 inch deck. If your deck uses two blades, you’ll have a spare.

Should You Buy It

Buy these if you own a compatible Snapper or Simplicity tractor with a 42-54 inch deck, want a reliable aftermarket mulching blade at a competitive price, and are comfortable with basic mechanical installation. Skip them if you need OEM exactness, have a non-standard deck size, or prefer a standard lift blade for bagging.
