2PK Lawn Mower Garden Tractor Anti Scalp Deck Roller Wheel Compatible with Simplicity 1668513, 1668513SM

What It Is

This is a set of two anti-scalp deck rollers designed to prevent mower deck scalping (scraping the turf) on uneven terrain. They are compatible with Simplicity lawn tractors and zero-turn mowers, intended for residential or light commercial use.

Fitment & Compatibility

Check before buying:

• OEM cross reference: Replaces Simplicity part numbers 1668513 and 1668513SM. Verify your mower’s OEM part number matches.
• Deck size: Fits most Simplicity decks up to 48 inches; confirm your deck has the correct mounting holes for these rollers.
• Brand/Model: Designed for Simplicity, but may fit certain Craftsman, Husqvarna, or other brands with compatible spindle mounts. Always compare your existing roller’s shaft diameter (typically 1/2 inch) and overall height.
• Measurements: Roller diameter is roughly 3 inches, wheel width about 1.5 inches. Measure your old roller to ensure the new one clears the deck shell and doesn’t interfere with blades.

Key Things to Know

• Quality vs OEM: These are aftermarket rollers priced lower than Simplicity OEM parts. Expect durable plastic wheels, but metal bushings may wear faster than OEM steel.
• Installation difficulty: Easy—usually requires removing a single bolt or clip per roller. No special tools needed, but check that you have the correct fasteners (not included in all kits).
• Common gotcha: Some users report the roller shaft is slightly loose in the mounting bracket; a washer or slight shim may be needed for a snug fit.
• Scalping prevention: Properly installed, these lift the deck edge 1–2 inches off the ground, reducing turf damage on hills and dips.

Should You Buy It

Buy this if you have a Simplicity lawn tractor or zero-turn with a deck that uses 1668513 rollers and you want a budget-friendly replacement. It’s a good value for typical residential mowing, but if you need heavy-duty durability for commercial use or exact OEM fit, consider the genuine Simplicity part.
