335-422 7037723BMYP Air Lift Kit for Sna-pper 28" and 33" blades, Replaces 3-7723, 60480, 7037723, 7060480, 7060480SM

What It Is

The 335-422 7037723BMYP Air Lift Kit is an aftermarket accessory designed to increase airflow and lift under the deck of Snapper 28-inch and 33-inch walk-behind mowers. It replaces worn or missing OEM lift kits (part numbers 3-7723, 60480, 7037723, 7060480, 7060480SM) to improve grass clipping discharge and reduce clumping in tall or damp grass.

Fitment & Compatibility

• Deck size: Only fits Snapper 28-inch and 33-inch side-discharge decks (not 30-inch or 36-inch models). Measure your deck width before ordering.
• Brand/model: Works with most Snapper rear-engine riders and walk-behinds that originally used any of the OEM numbers listed. Does not fit other brands (e.g., John Deere, Craftsman) without modification.
• OEM vs aftermarket: This is a direct replacement for the factory lift kit. Verify your existing kit is the same shape—some Snapper decks use a slightly different bracket design. Compare the mounting hole spacing (typically 3.5 inches center-to-center) against your current part.
• Measurement check: The kit includes a stamped steel lift blade and mounting hardware. The blade length is approximately 7 inches from mounting hole to tip. If your deck has a different lift blade length, it won’t fit.

Key Things to Know

• Quality: Made from stamped steel, not cast. It’s durable enough for residential use but may bend under heavy commercial use or hitting large obstacles.
• Installation difficulty: Easy—requires only a socket wrench and basic mechanical skill. You’ll need to remove the existing blade and spacer, then install the lift kit between the blade and the spindle. Tighten to manufacturer torque spec (typically 40-50 ft-lbs).
• Common gotcha: The kit includes a new blade bolt; do not reuse the old one if it’s worn or stripped. Also, the lift blade must be oriented correctly—the curved side faces upward toward the deck for proper airflow. Installing it upside down will severely reduce lift and cause poor discharge.
• Performance note: Works best with sharp, balanced mower blades. If your main blade is dull or damaged, replace it at the same time for optimal results.

Should You Buy It

If you own a Snapper 28-inch or 33-inch mower and notice clumping, poor discharge, or wet grass sticking under the deck, this $15.99 kit is a cheap fix that restores factory lift performance. It’s not for commercial use or other brands, but for residential Snapper owners, it’s a reliable, easy upgrade.
