Dutra D4K B Tractor for FS2019

Dutra D4K B for Farming Simulator 2019

The D4K-B was produced from 1964 onwards as a further development of the D4K.

The D4K-B was equipped with the six-cylinder diesel engine Csepel 613.15 (7983 cm³ displacement, 90 HP at 1850 rpm) driven. This engine was also used in some bus models of the manufacturer Ikarus.

For export to non-socialist countries, engines from other manufacturers such as Perkins or Scania were also used.

Including the creeper gears, the tractor with three-speed transmission and countershaft reached speeds of 1.0 to 25.3 km/h. Since the same transmission was always used, export variants with higher revving engines reached speeds of up to about 30 km/h.

Partly engines from Steyr (WD610) were used. The tractor was then called Steyr-Dutra 110 or Steyr-Dutra 1300. The WD610 engine is a further development of the 613 Csepel engine, which in turn was a licensed replica of a Steyr engine.

However, the WD (WD: water diesel) 610 is a direct injection engine, unlike the Csepel 613, which is a prechamber diesel. Its power is 105 DIN PS with just 5.995l displacement, it runs with a speed of up to 2300 rpm which accelerates the tractor to about 30 km/h.

As the Steyr engine delivers its highest torque at about 2200 rpm, but the Csepel engine at about 1800 rpm, a reduction gear was installed in the transmission of the Steyr-Dutra tractors, which reduces the transmission so that the Steyr engine reaches its optimum torque at PTO speed.

Thus the tractor ran at 2300 rpm with the reduction ratio even at only 25km/h, the 30 km/h it reached with direct drive. This also resulted in a doubling of the gears: 6 forward gears in the field group, 6 forward gears in the road group and a total of 4 reverse gears.

The D4K-B were particularly suitable for heavy soil cultivation. A total of about 15,000 D4K B were produced between 1964 and 1975. The largest export customer was the GDR, which purchased about 4,000 D4K B. The list price at that time was 39,500 marks from the German Central Bank, in Great Britain the cheapest version cost 3,445 pounds.

The D4K used in the GDR was replaced by the ZT 300 and the K-700. The agricultural production cooperatives only received subscription certificates for the K-700 if they could prove that a D4K had been scrapped. Therefore and in the course of the extraction of secondary raw materials, practically the entire GDR stock of D4K was scrapped [2].

The Hungarian-built Dutra 1000 (successor of the D4KB) had a safety cabin and could be entered through either a right or left side door. Its brake system is an air pressure controlled hydraulic brake, unlike the D4KB, which has a pure air pressure brake, controlling each wheel via an air pressure cylinder with brake linkage. But the engine is also a Csepel 613, and no changes have been made in the gearbox. The safety cab was designed to protect the tractor operators from accidents, because the old cab was basically just a weather roof and it offered no protection whatsoever if the tractor overturned. If the tractor overturned, the cab was simply crushed, which meant a high risk of serious or fatal injuries. The new safety cab has an integrated safety frame that keeps the cab stable even if it falls over, giving the driver a better chance of survival.

Although the Dutra 1000 was built from 1970 to 1975, it did not have the reduction ratio built into the gearbox as was the case in the Steyr-Dutra, which was built before 1970, so that only 3 gears each were available in the road and field groups.
