Key Insight
Transporting two Caterpillar 637D scrapers across the U.S. can cost upwards of $25,000–$35,000 per unit due to weight, length, and permit complexity. Splitting the machines into tractor and bowl sections may reduce costs but adds labor and logistical challenges.
Caterpillar 637D Background and Production History
The Caterpillar 637D is a twin-engine motor scraper introduced in the mid-1970s as part of CAT’s push to dominate high-volume earthmoving. Designed for large-scale highway, mining, and reclamation projects, the 637D features a push-pull configuration with a front tractor and rear bowl, each powered by its own diesel engine. The machine can self-load and haul over 50 cubic yards of material per cycle.
Caterpillar, founded in 1925, has produced thousands of 637-series scrapers, with the D model being a workhorse in the 1980s and 1990s. Though newer models like the 637K offer improved emissions and electronics, the 637D remains popular in resale markets due to its mechanical simplicity and raw power.
Transport Challenges and Cost Drivers
Moving a 637D scraper from California to Ohio involves several logistical hurdles:
To reduce costs and avoid restrictive states, operators often choose southern routes:
A contractor in Texas once purchased a 637D from Nevada and faced a $40,000 quote for direct transport. By splitting the machine and using two separate carriers, he reduced the cost to $28,000 total. However, reassembly took two days and required a crane rental, adding $3,500. The net savings were modest, but the flexibility allowed him to meet project deadlines.
Recommendations for Buyers and Sellers
Transporting CAT 637D scrapers across the country is a complex and costly endeavor. While the machines themselves are built for rugged performance, their size and weight demand careful planning when moved over public roads. Whether choosing direct haul or split-load methods, understanding the regulatory landscape and equipment limitations is essential to avoid surprises and keep costs under control. For buyers, the freight bill may be the deciding factor in whether a deal makes sense.

Transport Challenges and Cost Drivers
Moving a 637D scraper from California to Ohio involves several logistical hurdles:
- Weight: Each unit weighs approximately 105,000–115,000 lbs.
- Length: Overall length exceeds 50 feet, requiring specialized trailers.
- Axle Configuration: A 2+3+2 setup (jeep, trailer, stinger) may be needed, totaling 10 axles.
- Permits: Crossing multiple states requires oversize permits, with Missouri and Indiana among the strictest.
- Height Restrictions: Machines over 14'6" may require bucket trucks and police escorts in certain states.
- Mileage: ~2,400 miles
- Rate: $13–$15 per mile
- Total per unit: $31,000–$36,000
- Escort and permit fees: $2,000–$5,000 additional
To reduce costs and avoid restrictive states, operators often choose southern routes:
- California → Arizona → New Mexico → Texas → Arkansas → Tennessee → Kentucky → Ohio
- Avoids Missouri and Indiana’s height and axle restrictions
- May reduce escort requirements and permit complexity
- Tractor unit on a 6-axle beam trailer
- Bowl on a 6-axle lowboy
- Reduces per-load weight and height
- Adds labor cost for disassembly and reassembly

Recommendations for Buyers and Sellers
- Always request quotes from multiple carriers, including platforms like UShip.
- Confirm axle and permit requirements for each state on the route.
- Consider hiring a logistics broker familiar with heavy equipment.
- If splitting the machine, ensure both ends have proper lifting equipment and skilled technicians.
- Factor transport cost into the total purchase decision—freight may exceed machine value.
