2 Pcs 3131072001 Roller Wheel Compatible with EGO Power+ Z6 42" Zero Turn Riding Mower, Fits ZT4200L ZT4204L Models

What It Is

This is a set of two replacement roller wheels (part number 3131072001) designed for the EGO Power+ Z6 42-inch zero-turn riding mower. These wheels support the mower deck to prevent scalping and protect the deck from ground contact during uneven terrain mowing.

Fitment & Compatibility

Before buying, verify your model is one of these: ZT4200L or ZT4204L (both are 42-inch deck versions of the EGO Z6). This part is not compatible with the 52-inch deck models (ZT5200L, ZT5204L) or older EGO push mowers. Measure your existing roller wheel’s outer diameter (should be ~5 inches) and axle hole size (typically 0.5 inches). OEM part number is 3131072001; this is an aftermarket replacement, so check that the mounting bracket spacing matches your deck—some aftermarket versions may use slightly different bushings or washers.

Key Things to Know

• Quality: Aftermarket plastic wheels may be less durable than OEM. Check for solid construction with no cracks or thin spots—these wheels take heavy side loads when turning.
• Installation: Easy DIY job—remove a single bolt and slide the wheel off. No special tools needed, but you may need to support the deck with a jack or blocks.
• Common gotcha: The axle bolt can rust or seize; apply penetrating oil before removal. Also, verify the included hardware matches your deck—some aftermarket sets omit washers or lock nuts.
• Wear indicator: If your current wheels are worn flat or cracked, replace in pairs to maintain even deck height.

Should You Buy It

If you own an EGO Z6 42-inch zero-turn and need a budget-friendly replacement for worn or damaged deck roller wheels, this set works—just confirm the fitment and inspect the plastic quality upon arrival. For heavy commercial use, consider OEM parts for better longevity.
