The 4200 series models, which went on sale in the summer of 1997, offered familiar basic technology in new bodies. More advanced technology was available as an option, but for example, the electro-hydraulic lift was priced so that only a small portion of buyers opted for it.

The 4255 (95 hp) was the successor to the 398, meaning it was the largest 4-cylinder model, equipped, as usual, with a wastegate turbo. The 4260 was a 100 hp six-cylinder, and the new flagship of the series was the 4270 (110 hp). The 4255 and 4270 were also promised to have a few extra bonus horsepower. The importer equipped some 4270 models with a turbocharger, increasing the power rating to 130 hp.

Compared to the smaller models, these had, among other things, more robust axles both front and rear, mixing adjustment for the lift hydraulics, and in Finland, 38" rear wheels. The six-cylinder models featured key switch cut-off, a reinforced rear housing, and 40 mm auxiliary cylinders on the lift, achieving a lifting capacity of 5000 kg. Unfortunately, the tractors were equipped with pushrod sensing for the lift. The six-cylinder models were also fitted with an additional fuel tank.

The transmission options initially were either 18+6 or 12+12 (see 4215-4245). In 1999, a hydraulic shuttle became available as an option, which could also be equipped with a creeper gear for a total of 24+24 speeds. A common problem with the transmissions is that the first gear in the largest range is too fast, which, combined with the main and range gears controlled by the same lever, makes starting to move with a heavy load difficult. The four-wheel drive and differential locks for both axles were electrically engaged, and now the four-wheel drive also engaged during braking.

The most important innovation in the 4200 series was the cab, which, however, was not quite up to the current standards. The noise level was relatively high, and for example, the single-lever gear shift and the positioning of the lift levers left something to be desired. Additionally, the gear shifting mechanism had the problem of the range shift spring breaking. On the other hand, visibility from the cab was good.

The 4200 series lineup included about ten different transmission options, five types of driven front axles, four different rear axles, and a large number of other equipment options, so the information provided here applies only to models sold in Finland. Elsewhere, versions sold may often be much more basic compared to those sold in Finland.
