The Evolution of Earthmoving Machines
Track loaders and dozers have long been staples in the earthmoving world, each with distinct strengths shaped by decades of engineering refinement. The track loader traces its lineage to the Drott 4-in-1 bucket systems of the 1950s, which transformed crawler tractors into versatile loading machines. By the 1970s and 1980s, manufacturers like Caterpillar, Case, and International Harvester had developed dedicated track loaders such as the CAT 955 and Case 1155D, combining digging, grading, and loading capabilities into one compact platform.
Dozers, on the other hand, evolved from agricultural crawlers into specialized grading and pushing machines. The Caterpillar D6 series, first introduced in the 1940s, became a benchmark for mid-sized dozers. With the introduction of six-way PAT (Power Angle Tilt) blades and hydraulic rippers, dozers gained precision and power for shaping terrain, especially in road building and site preparation.
Sales data from the early 2000s showed that compact track loaders were outselling dozers nearly 3 to 1 in the rental and light construction markets, driven by their versatility and ease of transport. However, in heavy-duty applications like mining, forestry, and large-scale grading, dozers still dominated.
Choosing the Right Machine for Motocross Track Building
When constructing or maintaining a motocross track, the choice between a track loader and a dozer depends on terrain, material type, and the nature of the work. Motocross tracks often involve reshaping hard clay, moving rocky soil, and sculpting jumps and berms with precision.
A dozer excels at pushing bulk material over short distances. With a wide blade and high tractive effort, it can cut through compacted surfaces and shape long straights in a single pass. For example, a D6C weighing around 18 tons can push material efficiently across 100-yard stretches, making it ideal for rough grading and slope formation.
However, dozers struggle with loading tasks and lack the finesse of a bucket-equipped machine. Track loaders, especially those with 4-in-1 buckets and rear rippers, offer greater flexibility. They can dig, carry, spread, and back-drag material, making them suitable for fine grading, jump shaping, and clearing debris. A Case 1155D, weighing 27,000 pounds and powered by a Cummins 6-cylinder engine, is a prime example of a loader that balances power with versatility.
Transmission and Steering Considerations
The choice of transmission and steering system significantly affects operator fatigue and productivity.
Bucket Configuration and Attachments
The 4-in-1 bucket is a game-changer for track loaders. It combines:
Rippers mounted on the rear of the machine help break up compacted soil and rocky layers, improving bucket penetration and reducing wear.
Operator Insights and Anecdotes
One former motocross rider turned contractor shared his experience maintaining tracks in Finland. Initially using agricultural tractors and wheel loaders, he found they lacked the ability to cut braking bumps and shape jumps effectively. Switching to a D6C dozer with a six-way blade dramatically improved efficiency and fuel economy. He later added a Komatsu D41S track loader for material handling and reshaping, finding the combination ideal for both rough and fine work.
Another operator in Virginia opted for a Case 1155D with a 4-in-1 bucket and rippers, calling it “the perfect beast” for motocross construction. The machine’s weight and power allowed him to clear land, sculpt jumps, and maintain the track with minimal downtime.
Terminology Clarification
For motocross track construction and general dirt work, the track loader emerges as the more versatile choice. Its ability to dig, carry, grade, and clear makes it a one-machine solution for most tasks. However, pairing it with a mid-sized dozer like the D6C can offer the best of both worlds—bulk pushing power and fine sculpting control.
Ultimately, the decision should be guided by terrain type, job scope, and operator preference. Machines with hydrostatic transmission, pedal steer, and 4-in-1 buckets offer the greatest flexibility and ease of use. Whether shaping jumps or clearing clay, the right equipment turns a challenging job into a rewarding craft.

Transmission and Steering Considerations
The choice of transmission and steering system significantly affects operator fatigue and productivity.
- Hydrostatic Transmission: Offers infinite speed control and automatic braking when in neutral. Ideal for precision work and tight maneuvering.
- Powershift Transmission: Provides reliable gear-based control, suitable for medium-duty applications.
- Direct Drive: Less common in modern machines due to higher operator workload and reduced efficiency.
- Pedal Steer: Allows hands-free directional control, freeing the operator to manage bucket and blade functions simultaneously.
- Lever Steer: Requires manual input for direction, increasing fatigue and reducing multitasking efficiency.
Bucket Configuration and Attachments
The 4-in-1 bucket is a game-changer for track loaders. It combines:
- Standard bucket for digging and carrying
- Dozer blade for pushing
- Clamshell for grabbing and dumping
- Leveling edge for back-dragging
Rippers mounted on the rear of the machine help break up compacted soil and rocky layers, improving bucket penetration and reducing wear.
