Technical Specifications and Performance: Power and Precision
The Case 990 boasts a David Brown 3.2-liter, four-cylinder diesel engine, a cornerstone of the Case-David Brown partnership. Official Case claims put its power take-off (PTO) horsepower at approximately 52.9 hp, and drawbar horsepower around 45.2 hp. However, independent tests revealed slightly higher figures: 53.77 hp at the PTO and 45.68 hp at the drawbar, a testament to the variations in testing methodologies. While impressive for its time, these figures pale in comparison to the vastly increased power output of modern tractors. Isn't it remarkable how far technology has advanced?
Power transmission is handled by a 12-speed, partially synchronized transmission. While less refined than today's fully synchronized gearboxes, it provided adequate functionality for the era. The 17.9-gallon fuel tank (67.8 liters) minimized refueling interruptions during long workdays, a significant advantage for farmers.
The hydraulic system, while utilizing a less-efficient open-center design compared to later closed-center systems, delivered a respectable 2000 lbs (907 kg) of recommended lift capacity, with a maximum capacity of 4250 lbs (1928 kg). This substantial lifting power facilitated the handling of the era's agricultural equipment. Further enhancing usability, power steering and hydraulic brakes significantly improved control and operator comfort. The addition of a weatherproof cab provided essential protection from the elements, improving operator well-being.
Design and Features: Form and Function
The 990's design exemplifies the typical tractor construction of its time: sturdy, robust, and built for longevity. While lacking the ergonomic sophistication of modern tractors, its practicality is undeniable. The control layout and visibility, unique to its era, are endearing characteristics for collectors and restorers. Many enthusiasts appreciate the machine's simple yet effective design.
Historical Context: A Product of its Time
Manufactured at Meltham Mills in England, the Case 990 represents a key moment in agricultural history, a product of the successful collaboration between Case and David Brown. This partnership epitomizes the industry's mergers and collaborations during that time. Its market positioning likely targeted farmers seeking a dependable, reasonably powerful, and well-constructed tractor. Precise sales figures remain elusive, but its enduring presence and continued restoration efforts suggest a significant market impact.
Restoration and Maintenance: Preserving a Legacy
Restoring a Case 990 presents both challenges and rewards. A primary obstacle lies in parts availability. Original parts may require extensive searching, often relying on online forums and specialized suppliers. However, dedicated enthusiasts and restorers continue to preserve this piece of agricultural heritage.
