731-3005 Anti-Scalp Deck Roller 6-Inch * 2-1/2-Inch - by DECKMAN, Compatible with MTD Stens 210-310 Cub Cadet, Fits 46" and 50" deck Rotary (1)

What It Is

The 731-3005 anti-scalp deck roller is a 6-inch by 2-1/2-inch wheel that mounts to the underside of your mower deck to prevent the blade from digging into the grass or ground on uneven terrain. It’s designed for use on 46-inch and 50-inch rotary decks from MTD, Cub Cadet, and similar models.

Fitment & Compatibility

Before buying, confirm your mower deck size is 46” or 50” and that it uses a roller with a 6-inch diameter and 2-1/2-inch width. This part is a direct replacement for OEM Cub Cadet part 731-3005, MTD 731-3005, and Stens 210-310. Check your deck’s mounting bracket spacing—this roller fits standard stamped-steel brackets found on many MTD/Cub Cadet zero-turn and lawn tractors. Measure the existing roller’s diameter and width; if your old roller is smaller or larger, this won’t fit. Also verify the axle hole size (typically 1/2-inch) and that your deck has the correct bolt pattern for the included hardware.

Key Things to Buy

• Quality: DECKMAN’s version is an aftermarket replacement, not OEM, but uses durable nylon/polyethylene material that resists cracking and wear. It’s lighter than steel and won’t rust.
• Installation: Easy—usually requires removing a single bolt and sliding the old roller off, then sliding the new one on and tightening. No special tools needed.
• Common gotcha: The roller can be tight on the axle if the bracket is bent or rusted. Clean the axle and bracket before installing. Also, check that your deck’s mounting holes align—some older decks have slightly different spacing.
• Alternative use: Works as a front or rear anti-scalp roller on most MTD/Cub Cadet decks, but not on side-discharge chute rollers.

Should You Buy It

If you own an MTD or Cub Cadet mower with a 46” or 50” deck and your current anti-scalp roller is worn, cracked, or missing, this is a solid, affordable replacement. It’s not OEM, but the build quality is good for the price, and installation is straightforward. Avoid if your deck uses a different roller size or if you need a steel roller for heavy commercial use.
