Nuffield / Leyland / Marshall

Here is the translation of the provided text into English:

---

The 6-cylinder models 285 and 2100 were more robust than the 4-cylinder ones in many ways: they had more lifting power, oil-immersed brakes, hydrostatic steering, a standard 1000 rpm power take-off, and a stronger rear axle manufactured by County. The 6-cylinder models were also equipped with County four-wheel drive, in which case the model designations were 485 and 4100. In Finland, these models also used the British Victor Euroscan cab. The 285–4100 models also received silver-colored striping at the same time the 262 and 272 were introduced.

In the autumn of 1975, the model 255 was replaced by the 262, and the 270 was replaced by the 272. The visible difference compared to the previous models was the silver-colored stripes. Along with the new model series, Finland also switched to the original Q-cab manufactured by Victor, which was criticized for inadequate ventilation, high noise levels, and peculiar pedals.

Primarily, international technical data has been used here. In Finland, power was indicated somewhat higher according to the BS standard. Lifting capacities and other specifications were also reported as higher in Finland.

Tractors

Leyland 262-4100

In the autumn of 1984 the six-cylinder Marshall 100 was introduced, using the same Leyland 6/98 engine as the six-cylinder Leyland tractors. The engine developed 103.5 hp. A little later that same year the turbocharged Marshall 115 was launched, its horsepower rating matching its model designation. Both engines were equipped with a viscous fan. The 100 was also available as a two-wheel-drive model, while the 115 was only offered in four-wheel drive. In 1988 the 125 was introduced to replace the 115.

The gearbox offered 20 forward and 9 reverse gears, of which 8 forward and 4 reverse were in the so-called creep range. Even in the lowest gear the maximum speed was 1.6 km/h. The transmission, made by ZF, was largely the same as in the IH 1255/1455. The clutch was 13 inches in diameter. The cab, made by Sekura and called the Explorer, was almost identical to those in the smaller models, though the interior trim had been slightly upgraded. The new technology feature was an electric lift. Lifting capacity was 4.5 tonnes and feedback was through the draft arms. The front driveline shaft for four-wheel drive was on the left side. A trailer brake valve was standard equipment.

Production of the Marshall 100 continued until 1989, as did that of the smaller Marshalls. The 115 and 125 remained rare. After Leyland engines went out of production, there were plans to continue these models with Perkins engines, but that project never progressed beyond the prototype stage.

Marshall 100-125

For the year 1981, the Leylands turned yellow. The 262 was replaced by the 602, the 272 by the 702, and the turbocharged 282 by the 802. The corresponding 4-wheel drive models had a model number ending in 4. The 502 equipped with a Perkins 3-cylinder engine and the small tractor 302 were not imported to Finland. The cab in the models brought to Finland was the Sekura Explorer. A more basic QM cab based on the old design was also available. Exterior changes were minimal, but there were more updates in the technology.

The hydraulics now featured a double pump with a capacity of 55 liters per minute, and the hydraulics were powered directly from the engine. Draft control was still in use. The brakes were now oil-immersed.

Marshall bought Leyland's tractor production in 1981, and the brand changed to Marshall at the end of 1982. At the same time, imports to Finland ended. The Marshalls also had XL versions, which included crawler gears (15+5) and a slightly longer wheelbase. The lineup was expanded with the 92-horsepower 904 at the end of 1984. The small 302 was replaced in 1986 by the angular 132. It was essentially an IMT 539 fitted with Marshall fenders and a Duncan cab. It had a 35-horsepower Perkins engine manufactured by IMT.

Leyland / Marshall 302-804

In March 1978, the old 10+2 gearbox was replaced with a synchronized 9+3 gearbox. The gearbox was one of the first where engaging the reverse gear was possible without completely stopping the tractor. However, the range gearbox was still unsynchronized. The range shift lever was on the left side of the driver, and the main gear shift was on the right. The external change was the red stripes on the decals. New features introduced included the four-wheel-drive models 462 and 472, equipped with a Carraro front axle and a central driveshaft.

At the end of 1979, a turbocharged 282/482 (82 hp) was introduced, and with its introduction, the production of 6-cylinder models ended.

From the beginning of 1980, the models imported to Finland were equipped with the Sekura cab.

The last attempt to revive Leyland tractors was JWD, which bought the remains of the Marshall factory. Like the Marshall 752-954, Perkins engines were used in JWD Fieldmasters. In the 274/474 models, the engine was naturally aspirated, and in the larger ones, turbocharged. The standard number of gears was 9+2, meaning the previously largest reverse gear was no longer available. With creeper gears, the total was 15+4 gears.

The brochure mentions that the clutch was redesigned. Otherwise, the differences in technical specifications compared to the Marshalls were limited to tire sizes and a smaller fuel tank than before. The Explorer cab was also unchanged. Only the gauges looked different compared to the Marshalls. The cab could be tilted to the side for maintenance work.

JWD production ended in 2003, and only about 50 tractors were manufactured.

In 1987, the Leyland-based models were replaced with new Marshall 752/754, 852/854, and 954 models, which featured Perkins 3.9-liter engines. The angular exterior was new, but the Explorer cab remained almost unchanged. However, the cab now had a separate cold air blower and an air filter that was easier to clean. The transmission in the X models was the old 9+3, and in the XL models, it was a 15+5 with crawler gears. The drivetrain was partially reinforced. The front-mounted fuel tank was significantly larger than before. All models now had a long wheelbase, which resulted in a large turning radius.

Sales of Marshall remained low, and production ended in 1989. After this, Steyr tractors were sold for a short time as Marshalls in England.

Marshall 752-954

At the end of 1972, the Leyland model designations were updated: the 253 became 245, the 344 became 255, and the 384 became 270. The last digits indicated the engine power. The updated engines of the 255 and 270 featured, among other things, larger valves and thicker cylinder liner walls. In Finland, the 3- and 4-cylinder models were still equipped with a Junkkari cab instead of the original Q cab. The 245 received the Q cab in 1976.

At the same time, the lineup was supplemented with 6-cylinder models 285 and 2100 (see 262-4100).

More from this manufacturer

William Morris, the founder of Morris Motors, later became Lord Nuffield, and he gave that title to Morris’s agricultural division, which was established in 1948. At the 1948 Smithfield Show, the Nuffield Universal M4 and its petrol‐fuelled version, the PM4, were introduced, along with the three‐wheeled M3, which was aimed primarily at the American market. Their engine was the side‐valve unit from a Morris commercial truck. In 1950 the DM4 was unveiled, fitted with a Perkins diesel engine. The petrol engine’s displacement grew from 3.2 liters to 3.8 liters in 1952. After Morris Motors merged into BMC, the diesel engine was replaced in 1954 by one of BMC’s own designs. By 1955, diesel models accounted for 95 percent of production.

At the time, the Nuffield was a fairly large tractor. The petrol version produced 48 hp, had five forward gears, and could reach almost 30 km/h on the road. It used an 11-inch Borg & Beck clutch and a 12-volt electrical system. The rear‐axle track width was adjustable in true American style—infinitely—by sliding the wheels along the axle.

Nuffield Universal M4-DM4

Nuffield was an early user of direct injection diesel engines: already in 1954, the DM4 model equipped with a Perkins engine, which replaced the previous model (later known as the 4DM), was introduced to the market, and alongside it came the three-cylinder 3DL in 1958. At this point, the models were also known by the designations Universal Four and Three. These models had BMC engines with displacements of 2.5 and 3.4 liters. A differential lock was added in 1959. A dual clutch had already been offered since 1956.

In 1962, improved models 3/42 and 4/60 were introduced. The model numbers indicated the number of cylinders and power output. The displacement of the larger model had increased from 3.4 to 3.8 liters. There were still 5 forward and 1 reverse gears, and multipliers were installed in Finland. A differential lock and draft sensing lift arms were standard. As an option, a power take-off independent of the drive clutch and power steering for the larger model were available. Finland was Nuffield’s most important export market outside the British Commonwealth.

At the end of 1964, the 10+2 speed 10/42 and 10/60 models were introduced. The smaller model’s engine grew to 2.8 liters and a reduction gear was added to the transmission. The brakes were now disc brakes, and the hydraulics featured a dual pump. The dashboard was redesigned, and starting was now done with an ignition key. In 1965, hydraulic output was increased from 31.5 to 35 liters.

In Nuffield’s history, as with Ford, are four-wheel-drive models modified by external British manufacturers, of which Bray Four 10/60 models were also imported to Finland, featuring front wheels equal in size to the rear wheels. Italian front axles were installed in the Universal Four models in Finland.

Nuffield 3DL – 10/60

In 1965, the small tractor BMC Mini 9/16, mainly developed by Harry Ferguson Research Ltd, was introduced to the market. The Mini had a hydraulic pump above the engine and a fuel tank under the seat. Unlike many other small tractors, it was equipped with draft sensing. The original engine was a 950 cc gasoline engine, and shortly thereafter, a 948 cc swirl chamber diesel (15 hp) was also introduced. In 1968, the name was changed to Nuffield 4/25, and the engine options were a 1.5-liter gasoline or diesel.

In 1969, the small tractor was also renamed Leyland. The grille changed, and the color switched to blue. The model number was always Leyland 154, despite the tractor being equipped with both a 1.5-liter diesel and a 1.6-liter gasoline engine.

The model remained in production until 1980, despite relatively low sales, when it was replaced by the 235 model equipped with a 1.8-liter, 30-horsepower diesel engine. The model's story continued in the 1980s in Turkey, where it was manufactured as the red Leyland 184 and exported as the yellow 302 until 1985.

BMC Mini, Leyland 154

The Nuffields had looked almost the same for a long time, but in 1967 excessive styling took over. Unlike the competitors’ angular new models, the exterior was still rounded, but there was plenty of ornamentation. The 3/45 was a 3-cylinder model and the 4/65 was a 4-cylinder. The DIN horsepower ratings were 45 and 60 hp, while the SAE figures were 50 and 70 hp. The engine was not part of the load-bearing structure.

There were 10+2 gears as before. The hydraulics were more powerful than before. The cab and the arrangement of the controls were redesigned. In Finland, Nuffields were equipped with a Junkkari cab. Both models came in two versions: an economy model and an estate model, the latter featuring a dual clutch, and in the 4/65 estate model additionally power steering. The clutch was 11 inches in diameter. In some countries, the 4/75 was also known, with increased power of 66 horsepower by raising the nominal engine speed to 2400 rpm, and it also had larger wheels.

Nuffield 3/45 – 4/65

BMC merged with the Leyland group in 1967, and the tractors were renamed Leyland instead of Nuffield. The first Leylands were the 344 and 384, introduced at the end of 1969. They were equipped with 3.4- and 3.8-liter four-cylinder engines, a 10+2 transmission familiar from the Nuffields, and a dual clutch. The model numbers indicated the engine displacement and number of cylinders. Compared to the Nuffields, the most noticeable changes were the blue color and new design. In addition, efforts had been made to reduce vibration and noise as well as to improve the placement of controls.

At the end of 1971, the 253 model was introduced, equipped with a Perkins 2.5-liter three-cylinder engine (47 hp). The technical differences between this model and the larger Leylands were quite minor. Power steering was available as an optional extra, as it was on the bigger models as well. The cab used in Finland and manufactured by Junkkari resembled the factory-fitted cab in design but had slightly smaller windows.

In Finland, Leylands were sold as Economy and Manor models, the latter featuring hydraulics and a power take-off independent of the drive clutch, as well as power steering.
