Snow Plow Blade Types: Straight, V-Plow, Wing, and Underbody

Snow plows come in four basic types — straight, V-plow, wing, and underbody — and each one places different demands on its cutting edge. The blade type determines the mounting position, the cutting geometry, and the wear pattern, which means the cutting edge should be selected for the plow, not just for the truck. The snow plow blade product lineup covers cutting edges for all of these applications.

Different Types of Snow Plow Blades

The four families are straight blades (the universal workhorse), V-plows (directional control for heavy snow), wing plows (wide coverage on large roads), and underbody blades (truck-mounted scraping). Each has a distinct cutting edge profile and mounting pattern, so blade selection starts with knowing which family your fleet runs.

Straight Blades Explained

Straight blades are the most common: a flat moldboard mounted on the front of a truck or loader, pushing snow to the side. Their cutting edges carry the full scraping load and wear fastest, which is why carbide edges on straight blades deliver the biggest cost-per-mile improvement on highway duty.

V-Plows and Their Uses

V-plows angle into a V shape to break through deep drifts and push snow to both sides. The cutting edge works at an angle and takes heavy impact when hitting drifts and ice. Carbide edges with strong insert retention are preferred because drift impacts punish weak bonds.

Wing Plows for Large Roads

Wing plows extend the plow’s reach to clear shoulders and multiple lanes in fewer passes. Wing edges run at sharp angles and often contact gravel shoulders, which is extremely abrasive. Carbide cutting edges on wings extend service life where steel fails quickly.

Choosing the Right Blade Type

Choose the plow type by duty — depth of snow, road width, and clearing speed — then choose the cutting edge by wear and surface conditions. The Clear Roads program evaluates high-performance blades across these real-world duty profiles so agencies can match edges to applications.

Cutting Edge Needs by Mounting Position

Front edges take the full load and wear fastest; wing edges run against abrasive shoulders; underbody edges scrape packed ice under trucks. Each position needs a different balance of wear resistance, impact strength, and surface protection — one blade specification does not fit all positions.

Underbody Blades for Truck Duty

Underbody blades mount beneath trucks to scrape hard-packed snow and ice. They operate close to the pavement at speed, so edge geometry and surface protection matter as much as wear life. Carbide underbody edges reduce changeouts on high-mileage trucks.

Carbide Configurations for Each Position

SENTHAI configures carbide blades for front, underbody, and wing mounting, including reverse operation with tungsten cladding where needed. Matching the configuration to the position is what turns a good blade into a long-lasting one.

Wing Plow Edge Profiles and Angles

Wing edges cut at steep angles against gravel and pavement edges, so profile and attack angle determine both wear life and shoulder contact. Ask for edge profiles engineered for wing duty rather than using a front-edge blade.

Upgrading an Existing Plow’s Edge

Upgrading a plow to carbide edges is usually a direct fit: standard AASHTO bolt patterns and existing clamping hardware. The upgrade changes wear life and cost per mile without changing the plow — the fastest winter-fleet improvement available.

Frequently Asked Questions

Which plow type wears edges fastest?

Wing and underbody edges face the harshest conditions — abrasive shoulders and close pavement contact — while front straight blades carry the largest scraping load on long routes.

Can I use the same blade on different plow types?

Only if the bolt pattern and length match. The edge profile and material should still be matched to the position for best life.

Are carbide edges available for wing plows?

Yes. Carbide blades are manufactured for front, underbody, and wing mounting, with configurations for each position.

Is upgrading to carbide a direct fit?

Usually yes — standard AASHTO bolt patterns work with existing clamping bars and Grade 8 hardware, so the upgrade is a same-day changeout.
