The Rise of LeTourneau and the LP Series
LeTourneau Inc., founded by R.G. LeTourneau in the early 20th century, revolutionized earthmoving with electric-drive machines and massive scrapers that reshaped mining, agriculture, and infrastructure development. By the mid-1900s, LeTourneau had become synonymous with innovation in heavy equipment, producing some of the largest and most advanced machines of its time.
The LP series scrapers—short for “Low Profile”—were tractor-drawn units designed for bulk earthmoving in open terrain. These machines were built with simplicity, durability, and capacity in mind. The LP scraper was typically paired with a high-horsepower tractor and used in road building, land leveling, and dam construction. Though production numbers were never officially published, thousands of LP scrapers were manufactured and deployed across North America, Australia, and parts of Africa.
Terminology Clarification
When encountering an old LP scraper sitting idle in a pasture, the first question is whether it holds value beyond scrap. While the machine may appear rusted, with dry-rotted tires and faded paint, its historical and mechanical significance can outweigh its immediate salvage value.
Scrap dealers may offer a few hundred dollars based on weight alone—an LP scraper can weigh upwards of 9.85 tons. However, antique equipment collectors and restoration enthusiasts often pay more for intact machines, especially those with original components. The cutting edge, apron linkage, and bowl geometry are of particular interest to restorers.
Restoration Potential and Historical Value
Restoring an LP scraper is not just a mechanical endeavor—it’s a preservation of industrial heritage. Many collectors view these machines as the “muscle cars” of earthmoving history. Their rugged design, mechanical simplicity, and connection to mid-century infrastructure projects make them prized additions to vintage fleets.
In California, a group of antique tractor enthusiasts restored an LP scraper and paired it with a rebuilt Caterpillar D8. The machine was showcased at a heritage equipment show, drawing crowds who remembered seeing similar rigs on highway jobs in the 1960s. The restoration involved:
Scrapping an LP scraper is not as straightforward as it seems. Dirt and debris packed into the bowl and frame can make torch cutting difficult. The steel is thick and often reinforced, requiring heavy-duty equipment and time-consuming labor. Additionally, separating cast components like the hitch or apron arms may require specialized tools.
Operators who have attempted to scrap similar machines report that the effort often outweighs the return—especially when factoring in labor, fuel, and torch consumables. In contrast, selling to a collector or restorer may yield a better financial and cultural outcome.
Recommendations for Owners of Idle Scrapers
If you inherit or discover an old LP scraper, consider the following steps:
In Queensland, Australia, a retired contractor found an LP scraper buried under brush on his property. Rather than scrapping it, he contacted a local machinery preservation group. They hauled it out, cleaned it, and restored it over two years. The machine now operates at demonstration events, pulling soil with the same grace it did half a century ago. The contractor remarked, “It’s like watching a dinosaur come back to life.”
Conclusion
The LeTourneau LP scraper is more than a rusted relic—it’s a symbol of a bygone era when mechanical ingenuity and brute strength built the foundations of modern infrastructure. While scrapping may offer quick cash, preserving these machines offers lasting value for historians, operators, and future generations. Whether restored to working order or displayed as industrial art, the LP scraper deserves a second life beyond the scrapyard.

Terminology Clarification
- Tractor-Drawn Scraper: A non-motorized earthmoving bowl pulled by a separate prime mover, typically used for cut-and-fill operations.
- Cutting Edge: The hardened steel blade at the bottom of the scraper bowl that slices into soil during loading.
- Apron: A hinged front gate that opens to allow material entry and closes to retain the load.
- Ejector: A rear-mounted plate that pushes material out of the bowl during dumping.
- Heavy Melt: A scrap metal classification for large, dense steel suitable for recycling.

In California, a group of antique tractor enthusiasts restored an LP scraper and paired it with a rebuilt Caterpillar D8. The machine was showcased at a heritage equipment show, drawing crowds who remembered seeing similar rigs on highway jobs in the 1960s. The restoration involved:
- Replacing tires with period-correct reissues.
- Rebuilding the apron linkage and hydraulic cylinders.
- Sandblasting and repainting in original LeTourneau yellow.
- Fabricating missing ejector components from archival drawings.

Recommendations for Owners of Idle Scrapers
If you inherit or discover an old LP scraper, consider the following steps:
- Document the machine’s condition with photos and serial numbers.
- Reach out to antique equipment clubs or online forums focused on vintage earthmoving gear.
- Avoid immediate scrapping—give restoration groups a chance to assess its value.
- If selling, highlight intact components like the bowl, apron, and ejector.
- Consider donating to a museum or historical society if commercial interest is low.
