David Brown / Case

In 1939, the era of the red Case tractors began. Significant steps were also taken in the design, including a curved grille in front of the radiator. The C model was replaced by the D, and the CC by the DC. The engine power was mainly increased by raising the engine speed. Both gasoline and kerosene versions were available. The number of gears was increased to four, so the highest gear was already sufficient for highway driving, since the maximum engine speed was 1550 rpm. The brakes were now oil-bath disc brakes, and power steering brakes were available as an option. In 1950, hydraulics were introduced in the D series, and in 1952 a lift equipped with a draft control system and a liquefied petroleum gas version were introduced. Both the hydraulics and the power take-off were independent of the clutch.

A year later, an updated version of the L model, the LA, was introduced. The engine's compression ratio was raised, and lubrication improved. There were four gears as standard, and the electrical system was available for an additional cost. Fuel options included kerosene, gasoline, and liquefied petroleum gas.

In 1941, the S model and its row-crop version SC were introduced below the D in the lineup. These replaced the R model, which had an outsourced engine. The new engine was 2.5 liters and primarily a gasoline version. This model also had four gears. The 1953 models featured an enlarged 2.7-liter engine.

There are quite significant differences in the reported power ratings. The LA model's power as a gasoline version was 55 hp both in the USA and in Finland. In Finland, the S-ex model was rated at 30 hp for the gasoline version and 27 hp for the kerosene version. For the D-ex, correspondingly, 40 hp and 37 hp. The export market ex-versions included, among other things, power steering brakes and a padded seat.

The stylish 90 series was introduced at the end of 1979. The 885 was replaced by the 1190, the 990 by the 1290, and the 996 by the slightly more powerful 1390. The smallest model in the series was rear-wheel drive, while the larger ones also had an all-wheel-drive model equipped with a Carraro front axle. The technical changes were less extensive than the still modern-looking exterior would suggest. The transmission was partially synchronized, and the hydraulic output and lifting capacity were modest. The use of Selectamatic hydraulics was simplified. The cab was still manufactured by Sekura but met the requirements of the 1980s. A larger fuel tank than before was placed under the cab on the left side. All models were equipped with dual clutches. Surprisingly, the 1190 had 12-inch clutch plates, while the 1290 and 1390 continued with 11-inch ones.

From 1983 onwards, the larger models’ well-known Hydra Shift transmission was also made available for the 1390, but only for the rear-wheel-drive model.

For the year 1983, the tractor brand also changed to Case in Europe.

The successor to the earlier 1200 model was the 1210, equipped with a partially synchronized transmission. At the end of 1974, a turbocharged 1410 was introduced above it, featuring oil-bath disc brakes and more powerful hydraulics. In Finland, the cabin was mostly the Taavi model, and partially the Swedish Klippan. The steering in these models was hydrostatic. In 1977, the cabin was replaced with a factory-installed, flat-floor Sekura. At the same time, the pedals were changed to a dependent type. The diameter of the dual clutch in models 1210 and 1410 was 305 mm, as in later models as well. In 1977, 4-wheel drive models were introduced in Finland too; these had been in the production program since the end of 1973. Smaller models had DB's own front axle, while the 1410 featured a German Kramer axle.

The four-speed Hydra Shift quick transmission was launched in 1972. It was only available for rear-wheel-drive models. Hydra Shift was introduced in Finland only in 1976. Based on two consecutive planetary gearsets, the Hydra Shift was ahead of its time, and among current four-speed quick transmissions, it only falls short in that after changing direction, movement always starts at the smallest gear of the selected range. Of course, similar systems had already appeared in large tractors in the USA in the 1960s.

At the end of 1965, David Brown Implematics were replaced by white Selectamatics. The new series got its name from the upgraded hydraulics, which offered adjustment of working depth, position control, and use of external hydraulics with a single control lever. The smallest model in the lineup was the 36-horsepower 2.4-liter 770. Of the models imported to Finland, the 990’s 3.0-liter engine remained unchanged, but the 880’s displacement had increased to 2.7 liters. The SAE horsepower ratings in Finland were 48.5 and 58 hp. The power take-off also featured a 1000 rpm speed. The 990 had an 11-inch clutch instead of 10 inches. AS models featured a dual clutch allowing for a power take-off independent of the clutch and had 12+4 gears. The basic gearbox’s lowest speed was quite high. A problem with the lifting device was the small lifting range.

In spring 1967, the flagship of the lineup was introduced: the 67-horsepower (71 SAE) 1200 Selectamatic. The 3.6-liter four-cylinder engine had the same cylinder dimensions as the 3-cylinder 880. The transmission was more robust than that of the smaller models. The dual-clutch plates were 11 inches and power was controlled by a hand lever. Unlike the smaller models, the hydraulic pump was independent of the clutch. A dual pump was available for the hydraulics, increasing flow from 22.7 liters to 52 liters. The 1200’s power was increased by five horsepower the following year. Another new model in 1967 was the 780, in which the 2.7-liter engine from the 880 was installed in the lighter structure of the 770. The 780 was also not imported to Finland. In 1970, four-wheel-drive versions of the 990 and 1200 were introduced, but these were not imported to Finland either.

The first David Browns brought to Finland were the Cropmaster model manufactured between 1947 and 1953. Its successor, the updated 25, was introduced in 1953. The power of these models was approximately 37 hp for the gasoline version, and about 30 hp for the petrol version and the direct injection diesel version. The 25 featured a simple power take-off system, a 2-speed PTO, and a foot throttle. The transmission was 6+2, as in later models as well. In addition to these models, a 15-horsepower utility machine carrier, the 2D, was sold here. On the other hand, the more powerful version of the 25D, the 30D, and especially the 6-cylinder 50-horsepower 50D remained rare in Finland.

The first model in the Case letter series was the L, introduced in 1929. It was designed to compete with the very successful John Deere D model. Besides plowing tasks, its use included driving a threshing machine via a belt pulley. The 6.6-liter, 4-cylinder petrol engine produced 45 horsepower. The final drive was implemented using roller chains. There were three gears, and the clutch was a manually operated, oil-bathed 2-plate clutch. In 1934, pneumatic tires became available. The industrial model LI featured steering brakes, 4 gears, and electric start.

A few months later, a smaller model C was released, designed for a 3×14" plow. The technical solutions were exactly the same, but the tractor was overall scaled down. However, the brake on the C was manually operated. The engine was 4.25 liters, and the power take-off output was rated at 27 horsepower. The Nebraska test measured 29.8 horsepower. A parallel model to the C was the row-crop model CC, offered in two versions. The 3-wheel version had the front wheel positioned in front of the front, and the 4-wheel version featured a wide, adjustable-width front axle. Steering brakes were standard on the CC. Optional equipment included power take-off, electrical system, and pneumatic tires. Starting in 1935, a manually operated lifting device became available. Other parallel models to the C included the orchard version CO and the industrial model CI.

Case acquired the French SFV Vierzon tractor manufacturer in 1958. Production in Vierzon initially continued with the old half-diesel models, and the tractors’ color changed from green to Case’s yellowish hue. The final models were the Super 204 and 403D, introduced in 1961. 

At the 1962 SIMA show, Case unveiled the CF 250 and CF 350—models partly based on American technology and equipped with French 1.8-liter Indenor diesels. At the same time, the Vierzon plant began assembling the American models 530, 630, and 730.

Both the CF 250 and CF 350 featured an 8+4 gearbox, a dual-clutch system, and a weight-transfer system. Each was also offered in a high-ground-clearance version (48 / 54 cm). In 1967, Case introduced a further developed version of the CF 350, the CF 400.
