MOTOQUEEN 1/2" Poly Cutting Edge Scraper Bar- Replacement for John Deere 54" Front Mount Snow Blade Plow, Replaces for M75679 Two-Part Assembly

What It Is

The MOTOQUEEN 1/2" Poly Cutting Edge Scraper Bar is a replacement wear blade for John Deere 54-inch front-mount snow plows. It scrapes snow and ice from driveways and pavement, designed to bolt onto the plow’s moldboard as a sacrificial edge that protects the plow from damage.

Fitment & Compatibility

• Primary fit: John Deere 54" front-mount snow blade (models 54, 54S, 54H, 54HC, 54HP, 54HS). Replaces OEM part M75679 (two-part assembly).
• Check your plow model: This fits only the 54-inch front-mount blade, not rear blades or smaller decks. Verify your blade model number on the frame tag or manual.
• Measurements: 1/2" thick, 54" wide poly cutting edge. Poly is softer than steel—expect faster wear on abrasive surfaces.
• Mounting: Uses existing bolt holes from the OEM two-part assembly. You’ll reuse your plow’s hardware (bolts, nuts, washers). No drilling or modification required if your plow originally took the M75679 edge.

Key Things to Know

• Material trade-off: Polyethylene is lighter and won’t rust, but it wears faster than steel on rough pavement or gravel. Best for smooth concrete/asphalt.
• Installation difficulty: Easy—unbolt old edge, bolt on new one. One person can do it in 20-30 minutes. No special tools needed beyond a socket set.
• Common gotcha: The edge is a single piece, not a two-part assembly like the OEM. Some users report it’s slightly less rigid than the original steel-and-poly combo. Tighten bolts evenly to avoid warping.
• Wear indicator: No built-in wear line. Check thickness periodically—replace when worn to 1/4" to avoid damaging the plow moldboard.

Should You Buy It

If you have a John Deere 54" front-mount snow blade and want a budget-friendly, rust-resistant replacement edge for light-to-moderate residential snow removal on smooth surfaces, this is a solid pick. Avoid it if you frequently plow gravel, heavy ice, or need the rigidity of the OEM steel-reinforced assembly.
