EPR 4PK Anti Scalp Deck Roller Wheel for Simplicity 1668513 1668513SM

What It Is

This anti-scalp deck roller wheel prevents the mower deck from digging into the turf during turns or on uneven ground. It’s designed for Simplicity and certain Broadmoor/Regent lawn tractors with 38- to 50-inch stamped steel decks.

Fitment & Compatibility

Before buying, confirm your deck uses OEM part numbers 1668513 or 1668513SM. This EPR wheel replaces those directly, so it fits Simplicity 1694286, 1694550, 1694554, 1694573, and similar decks. Measure your existing roller’s overall height (approx. 4 inches) and wheel diameter (approx. 3.5 inches). Check that your deck has two mounting holes spaced 2.5 inches center-to-center. This is an aftermarket part, not OEM, so it may differ slightly in plastic hardness or color.

Key Things to Know

• Installation difficulty: Easy. Remove the two bolts holding the old roller, slide the old one off, slide the new one on, and reinstall bolts. No special tools required.
• Quality: Users report the wheel is slightly stiffer than OEM, which can reduce bounce but may be louder on rough ground. The plastic seems durable for residential use.
• Gotcha: The included hardware may not match your deck’s bolt size exactly – check that your existing bolts are 5/16-inch or have M8 threads. If they’re different, reuse your original bolts.
• Deck clearance: Make sure the roller doesn’t contact the deck shell when installed – spin it by hand to verify free movement.

Should You Buy It

If you need a direct replacement for a worn or broken anti-scalp roller on a Simplicity or compatible tractor and want an affordable aftermarket option, this is a solid choice. It’s not for heavy commercial use, but for residential mowing it does the job without breaking the bank.
