8TEN Deck Roller for Simplicity SunStar Courier 1690252 1690271 40 42 60 Inch 1668513SM 1668513 4 Pack

What It Is

This 8TEN Deck Roller 4-pack replaces the OEM anti-scalp rollers on Simplicity SunStar and Courier zero-turn mowers, preventing grass scalping on uneven terrain by lifting the deck slightly.

Fitment & Compatibility

• Exact fit: Simplicity SunStar (40", 42", 60" decks) and Courier models with OEM part #1668513SM or 1668513.
• Check your deck size – 40", 42", and 60" decks use the same roller, but verify your existing roller diameter (approx. 4" OD) and axle hole size (5/8").
• OEM cross-reference: Replaces Simplicity 1668513SM, 1668513, and 1690252/1690271 for SunStar decks.
• Before buying: Remove one roller and measure the shaft diameter (likely 5/8") and roller width (about 1.5"). Confirm your mower model number (e.g., 1690252) on the frame plate.

Key Things to Know

• Quality: Solid urethane construction – more durable than OEM plastic, but slightly heavier. No premature cracking reported.
• Installation: Simple – remove a cotter pin or bolt, slide off old roller, slide on new one, reinstall pin. No special tools needed.
• Gotcha: The 4-pack covers most decks, but some 60" decks require 6 rollers (check your count). Also, ensure your axle isn’t rusted or bent before installing.
• Performance: Reduces scalping on bumpy lawns, but may slightly increase deck height – re-level after installation if needed.

Should You Buy It

If you own a Simplicity SunStar or Courier with worn, cracked, or missing deck rollers, this is a direct, affordable replacement. Perfect for DIY owners wanting to prevent scalping without paying OEM prices. Skip it if your deck uses different roller sizes (rare for these models) or if you need only 1-2 rollers.
