Originally designed by a road contractor for the construction industry, the Cat® MD1003 P Towed Scraper delivers outstanding performance and legendary durability. High-strength, abrasion-resistant steel in the scraper bowl minimizes wear. The rugged hitch, tongue, and structural design ensure long life in the toughest job site conditions. [. . . ] The exclusive walking-beam axle provides a smoother ride for the operator and a variable cutting edge angle for unmatched productivity. Designed to be pulled by Cat Track-Type Tractors or ChallengerTM Tractors, the Cat MD1003 P Towed Scraper raises the standard.
Scraper Bowl
Unmatched Durability.
High-Strength Bowl Design
The scraper bowl is constructed using L-shaped box sections of high strength steel for superior strength and dent resistance. The floor is a box-section structure made from high-strength, abrasion-resistant steel for maximum strength during top loading and rigidity during intermittent push loading. High-strength, abrasion-resistant steel is used throughout the inside of the bowl for maximum wear resistance.
Center Lift Design
The center lift design improves the strength and durability by placing the hydraulic cylinders between the tongue and spreader tube. This eliminates the need for draft arms, reducing weight and complexity.
Cutting Edges
Common Cat® Wheel Tractor-Scraper cutting edges and router bits are used to ensure exceptional performance and great availability. The center cutting edge is in the stinger (drop down) position for good penetration and efficient material flow into the bowl. When worn, the cutting edges can be rotated by 180 degrees, doubling the life.
Ejector
The ejector is constructed from a single plate of highstrength, abrasion-resistant steel. The ejector extends beyond the front edge of the scraper floor to minimize carryback. The exclusive design gives the scraper a smoother ride, reduced side-to-side sway and easier finish grading.
Adjustable Cutting Angle
The MD1003 P is equipped with an additional pair of lift cylinders at the rear of the scraper. An experienced operator can use this exclusive feature to fine-tune the cutting depth for improved productivity. Use a shallower cut when loading lighter materials such as sand or dry topsoil.
Wheels, Brakes
Raising the Standards.
Standard Brakes Construction-Grade
Standard heavy-duty brakes bring a new level of safety to the job site. The hydraulically-actuated, dry-disc brakes are identical to the brakes used on Cat D400E Articulated Trucks.
Standard Radial Tires
Standard radial tires reduce rolling resistance and provide excellent flotation and durability. Wheel hubs are oil-filled and sealed with Cat Duo-ConeTM seals.
