Before Bobcat Became Bobcat
Long before the name Bobcat became synonymous with compact loaders, the concept of a small, maneuverable machine for tight spaces was already taking shape in the American Midwest. The roots of Bobcat trace back to the late 1940s and early 1950s, when farmers and fabricators began experimenting with mechanical solutions to labor-intensive tasks like cleaning barns, hauling feed, and moving manure. These early machines weren’t branded, standardized, or mass-produced—they were often hand-built, modified from existing tractors or powered carts, and tailored to the needs of individual operations.
The idea of a compact loader wasn’t born in a corporate boardroom—it emerged from necessity. In North Dakota, two brothers, Cyril and Louis Keller, were approached by a turkey farmer who needed a machine that could operate inside narrow barn aisles. In response, they built a three-wheeled loader with a rear caster wheel and chain-driven front wheels. This prototype, completed in 1957, was the direct ancestor of what would become the Bobcat skid-steer loader.
Early Loader Designs and Mechanical Characteristics
These pre-1958 machines shared several traits:
The Keller Loader and Its Influence
The Keller brothers’ loader was a breakthrough. Its compact design, rear caster wheel, and front-mounted bucket made it ideal for barn work. The machine was powered by a 6-horsepower Kohler engine and featured a simple clutch system for directional control. It was not yet a skid-steer, but it laid the groundwork for what would become the industry standard.
In 1958, the Melroe Manufacturing Company of Gwinner, North Dakota, partnered with the Keller brothers to refine and produce the loader commercially. The result was the Melroe M-60, followed by the M-200 and M-400, which introduced true skid-steer functionality. By 1962, the machines were branded as Bobcat, and the rest is history.
Challenges of Early Compact Loaders
These early machines faced numerous limitations:
Legacy and Historical Significance
The machines built before 1958 were more than mechanical curiosities—they were the seeds of a global industry. Today’s compact loaders owe their existence to these early experiments in utility, simplicity, and adaptability. Bobcat, now a global brand with millions of units sold, continues to honor its roots with machines that prioritize maneuverability, versatility, and operator control.
In South Dakota, a museum exhibit features one of the original Keller loaders alongside modern Bobcat models. Visitors can see firsthand how a simple barn-cleaning tool evolved into a cornerstone of construction and agriculture.
Conclusion
Before Bobcat was a brand, it was a solution. The compact loaders built before 1958 were raw, practical, and deeply personal—crafted by hands that needed help and minds that refused to wait for someone else to invent it. These machines didn’t just move dirt—they moved the industry forward. And in every modern skid-steer, there’s a trace of that original spark.

Early Loader Designs and Mechanical Characteristics
These pre-1958 machines shared several traits:
- Small footprint for indoor or confined-area use
- Chain-driven wheels or tracks for traction
- Simple hydraulic or mechanical lift arms
- Gasoline engines repurposed from agricultural equipment
- Rudimentary operator stations with minimal shielding
- Manual controls with direct linkage to lift and tilt functions
- Skid-steer: A loader that turns by skidding its wheels, with no steering axle—introduced formally in later Bobcat models.
- Chain drive: A transmission system using chains and sprockets to transfer power from the engine to the wheels.

Challenges of Early Compact Loaders
These early machines faced numerous limitations:
- Limited lifting capacity due to small hydraulic systems
- Poor stability on uneven terrain
- Frequent chain tension issues and drive failures
- Lack of safety features like rollover protection or shielding
- Manual starting and unreliable ignition systems
- Upgrade to modern hydraulic cylinders with pressure relief valves
- Replace chain drive with hydrostatic motors for smoother control
- Add ROPS and seatbelt systems for operator safety
- Retrofit electric start and sealed wiring harnesses
- Use modern tires or tracks for better traction and flotation
