1668487SM - Snapper / Simplicity Deck Roller 2" X 3.5" - Original Snapper Part

What It Is

The 1668487SM is an OEM Snapper/Simplicity deck roller measuring 2 inches in diameter and 3.5 inches wide. It reduces scalping and protects the mower deck by guiding it over uneven terrain, primarily on 33-inch and larger Snapper walk-behind mowers and Simplicity lawn tractors.

Fitment & Compatibility

Check your deck model before ordering. This roller fits Snapper 33-inch, 36-inch, and 48-inch walk-behind decks (especially classic rear-engine riders) and Simplicity 48-inch and 50-inch fabricated decks. Confirm your existing roller’s dimensions—the 2" x 3.5" size is standard for these, but measure the shaft hole diameter (typically 3/8" or 1/2"). This is an OEM part, so it matches factory specs; aftermarket alternatives may use different bushings. If your deck uses a 1" x 3" roller, this won’t fit.

Key Things to Know

• Quality: OEM Snapper part, made from durable rubberized plastic—holds up better than cheap aftermarket rollers that crack in UV or heat.
• Installation: Simple bolt-on replacement—remove the old roller, slide on the new one, and secure with the retaining clip or cotter pin. No special tools needed.
• Common Gotcha: The roller’s internal bushing can wear out over time; if the roller wobbles after install, replace the bushing separately (part 1688487SM).
• Deck Compatibility: Not for zero-turn mowers or most newer Snapper Pro decks—verify your deck’s roller bracket spacing (3.5" width) before buying.

Should You Buy It

If you own a Snapper 33-48" walk-behind or Simplicity 48-50" tractor and need a direct OEM replacement, this roller is the right call. It’s affordable, easy to install, and built to last longer than generic options. Skip it if your deck uses a different size or you’re on a zero-turn—measure first to avoid returns.
