How Do Snowplows Work in Snow Removal Equipment?


When winter arrives with its white, icy embrace, the efficiency of snow removal becomes paramount for maintaining safety and accessibility. One of the most critical components of snow removal equipment is the snowplow. These specialized devices play a pivotal role in efficiently clearing roads, streets, and parking lots during snowy weather. This article delves into the intricate workings of snowplows, exploring their types, mechanics, and integration within snow removal equipment.

The Need for Efficient Snow Removal

Before we delve into the mechanics of snowplows, let’s emphasize the importance of efficient snow removal. Heavy snowfall can lead to hazardous road conditions, obstructed walkways, and even transportation disruptions. Prompt and effective snow removal ensures the safety and convenience of residents, commuters, and businesses.

Understanding Snowplows: Types and Functions

Snowplows are specialized attachments designed to clear snow from roads and other surfaces. They come in various types, each with its unique design and function.

  1. Straight Blade Plows: These are the most common type of snowplows. They feature a flat, rectangular blade that pushes snow to the side as the vehicle moves forward. Straight-blade plows are versatile and effective for a wide range of snow-clearing tasks.
  2. V-Plows: V-plows have blades that can be adjusted into a V-shape, making them particularly useful for breaking through heavy and compacted snow. They are ideal for larger snow removal projects and can easily cut through drifts.
  3. Wing Plows: Also known as winged plows, these have adjustable side panels that extend outwards, effectively increasing the clearing width. This design enhances efficiency when working on larger areas like highways.
  4. Scoop Plows: Scoop plows have a curved blade that resembles a scoop. They excel in pushing larger amounts of snow to the side in a single pass. These plows are effective for quickly clearing wide areas.
  5. Underbody Plows: Typically mounted underneath vehicles, underbody plows are great for clearing smaller amounts of snow from parking lots and tight spaces. They are often used in conjunction with other plow types.

Mechanics of Snowplows

Understanding how snowplows work requires insight into their mechanics:

  1. Mounting and Attachment: Snowplows are typically attached to vehicles such as trucks, loaders, and tractors. Hydraulic systems allow the plow to be raised, lowered, angled, and adjusted as needed. This flexibility is crucial for efficient snow removal.
  2. Blade Angle Adjustment: Many snowplows can be adjusted to various angles, allowing operators to direct snow off to the side. This feature is particularly useful for windrow management, preventing re-deposition of cleared snow.
  3. Hydraulic Power: Hydraulic systems provide the necessary power to lift and maneuver the plow. Hydraulic cylinders control the lifting and angling movements, enabling operators to adjust the plow’s position on the go.
  4. Cutting Edge: The bottom edge of the plow, known as the cutting edge, comes into direct contact with the snow-covered surface. It efficiently scrapes the snow off the pavement while minimizing damage to the road.
  5. Weight Distribution: Snowplows are designed with proper weight distribution to ensure efficient snow clearing. Too much weight on the plow can cause the vehicle’s front end to lift, reducing traction on the drive wheels. Thus, vehicles often use counterweights or ballast to maintain stability.

Integration within Snow Removal Equipment

Snowplows are integral components of snow removal equipment, working in tandem with other technologies to ensure effective snow clearing. Here’s how they are integrated:

  1. Salt Spreaders: After the initial snow clearing pass, salt spreaders are often used to prevent ice formation and improve traction. These can be mounted onto the same vehicle as the snowplow or operate independently.
  2. Snow Blowers: In areas with heavy snowfall, snow blowers may follow behind snowplows to clear snowbanks and drifts. These machines use powerful augers to break up and discharge large volumes of snow.
  3. GPS and Telematics: Modern snowplows often feature GPS and telematics systems, allowing operators to track their routes, monitor spreading patterns, and optimize snow removal efficiency.
  4. Advanced Materials: Snowplow blades are constructed from durable materials like steel and polyethylene. These materials are chosen for their ability to withstand the rigors of snow clearing while minimizing damage to road surfaces.

Snow Removal Techniques

Effective snow removal involves strategic planning and execution. Here are some techniques that snowplow operators employ:

  1. Pre-Wetting: Some snowplows are equipped with pre-wetting systems that spray liquid de-icers onto the road before plowing. This prevents snow from bonding to the pavement, making plowing more efficient.
  2. Anti-Icing: Before a snow event, anti-icing techniques involve applying liquid de-icers to road surfaces. This proactive approach prevents ice and snow from accumulating, making subsequent plowing easier.
  3. Snow Storage: When plowing large amounts of snow, proper snow storage is essential. Snow must be piled in designated areas to prevent obstruction and ensure proper drainage as it melts.
  4. Multiple Passes: Depending on the snowfall intensity, multiple plowing passes may be necessary to ensure thorough clearing. These passes also help prevent compacted snow from forming an impenetrable layer of ice.


In the battle against winter’s snow and ice, snowplows stand as stalwart defenders of safety and accessibility. These innovative devices, with their varied designs and precise mechanics, play an indispensable role in modern snow removal equipment. Understanding how snowplows work, their types, and their integration within snow removal practices sheds light on the complex process of transforming snow-covered landscapes into safe and navigable pathways. As technology continues to advance, the efficiency and effectiveness of snowplows in snow removal equipment will undoubtedly evolve, ensuring communities can brave winter’s challenges with confidence.
