What is a Pay Scraper?
A pay scraper, often referred to as a motor scraper, is a piece of heavy equipment that combines a scraper and a motorized vehicle. It is designed to scoop, transport, and spread earth or other materials over a construction site. The key components of a pay scraper include:
- Scraper Blade: This is the cutting edge or blade at the front of the machine that scrapes the material from the ground.
- Hopper or Bowl: The material scraped from the ground is collected in a large hopper or bowl mounted at the rear of the machine.
- Ejection System: After the scraper has collected enough material, it can transport the load to a designated area where the material is then ejected.
Key Features of International Harvester Pay Scrapers
- Durability and Strength
- One of the main reasons IH pay scrapers became so popular was their rugged design and high durability. These machines were built to withstand the harsh conditions found on construction and mining sites. The steel components, robust engine options, and powerful hydraulic systems made them suitable for heavy-duty tasks.

- Hydraulic Power
- IH pay scrapers relied on hydraulic systems to operate the scraper blade, bowl, and ejector. The hydraulic system enabled precise control over the depth and speed at which materials were scraped and ejected. Hydraulic control also allowed for smoother operations compared to earlier mechanical systems, improving the machine’s efficiency.
