Oregon 72-311-1 Wheel, Deck, Anti-Scalp, 5" x 2-3/4"

What It Is

The Oregon 72-311-1 is a 5-inch diameter by 2-3/4-inch wide anti-scalp wheel designed to replace worn or damaged deck wheels on select EGO lawn mowers. It prevents the mower deck from scraping or scalping the lawn during turns or on uneven terrain.

Fitment & Compatibility

• Primary fit: Designed for EGO 21-inch and 56-volt mower models, including LM2100, LM2101, LM2102SP, and similar series. Also compatible with some Craftsman and Greenworks models using the same wheel dimensions.
• Critical measurements: Confirm your existing wheel is 5" tall and 2-3/4" wide. Measure the axle hole diameter (typically 3/8" or 1/2") and the wheel hub depth to ensure the new wheel seats flush against the deck bracket.
• OEM vs aftermarket: Oregon is a direct replacement for the EGO OEM wheel (part #3122287001). It is not a universal fit—check your mower’s deck size (usually 21") and model number against Oregon’s compatibility list.
• What to check before buying: Remove one existing wheel and verify the axle bolt size and washer/spacer arrangement. Some EGO decks use a shoulder bolt; the Oregon wheel’s bushing must match.

Key Things to Know

• Quality: Solid aftermarket build with a durable plastic hub and rubber tire. Holds up well to regular use on turf, but not designed for heavy off-road or rocky terrain.
• Installation: Easy—remove the single bolt, swap the wheel, and re-tighten. No special tools required. Takes about 5 minutes per wheel.
• Common gotcha: The wheel may be slightly tighter on the axle than OEM. If it binds, check for debris or a bent bracket. Do not over-tighten the bolt; it should spin freely.
• Quantity: Sold as a single wheel. You may need two or four depending on your deck’s anti-scalp setup.

Should You Buy It

This is a straightforward, cost-effective replacement for EGO owners with worn or missing anti-scalp wheels. If your mower deck is dragging, leaving uncut strips, or scalping grass, this wheel solves it. Skip if you need a larger or smaller wheel, or if your mower uses a non-standard axle size.
