The tractor and implement carrier RS09 (RS = wheeled tractor) with the brand name Mole , later modified GT109 , GT122 or GT124 (GT = implement carrier ), affectionately called "Nulli", "Molli" or "Mull" by its drivers, became the successor to the RS08 and one of the most built tractors in the GDR and the Eastern Bloc as a whole. It was manufactured from 1955 to 1964, in small series for a few years after that, initially at the VEB Tractor Factory Schönebeck and later at VEB Agricultural Machinery in Haldensleben in the GDR.
technology
The RS09 is essentially a further development of the RS08 and, just like this, is designed as a frame construction device carrier. The RS09 has a front unsprung pendulum axle and a rear rigid axle. The engine is installed behind the rear axle, the transmission in front of it. The rear axle with the gearbox and engine forms its own unit, the longitudinal member connects the drive axle unit with the front axle. The RS09 is available in two basic versions , with a two-cylinder engine called GT122, GT109 or RS09 / 122, and with a four-cylinder engine called GT124 or RS09 / 124. One structural change is the additional fall cabin, which is intended to prevent the RS09 from rolling over if it tips over. The vehicle is designed as a bidirectional vehicle, the driver's seat above the rear axle can be rotated 180 °, the gearbox with four gears in two groups does not have a separate reverse gear, but can be switched to the corresponding direction of travel, so you can drive forwards and backwards at the same speed become. The tractor has a motor and a road PTO, the brake is a foot-operated inner shoe brake that acts on the rear wheels and can also be operated manually as a handbrake. The rear wheels can be braked independently of each other. A differential lock can also be activated. The steering is a horse steering . A three-point linkage can be installed at the rear of the tractor.
Engines
The first RS09 / 122 had an imported air-cooled and pressure-circulation-lubricated two-cylinder V- diesel engine from the Austrian company Warchalowski called FD 21 . The engine works with the four-stroke process and has a vortex chamber injection . Bore and stroke are 85 × 90 mm, the displacement is 1021 cm³. The engine has an output of 13.2 kW. From 1958 this engine was built under license at the Schönebeck diesel engine factory, the designation of the engines built under license is FD 21/1 . They provide 11 kW. From 1962 there was another revised engine, now with the type designation FD 22 . It is still based on the FD 21 type, but has been bored out to 90 mm, with the same stroke the displacement is 1145 cm³. The built-in injection pump provides an output of 12.1 kW. The same engine was designated as 2 KVD 9 SVL from engine number 25001 and was equipped with a different injection pump, the output increased to 13.2 kW.
From 1962, the GT124 , which was now being built in the VEB Landmaschinenbau Haldensleben , received the air-cooled diesel engine of the type 4KVD 8 SVL , also called "Cunewalder", developed and manufactured in the VEB engine factory in Cunewalde .

RS09 in the GDR
The RS09 implement carriers were by far the most important working machines in the LPG and VEG of the GDR in the 1960s , even the architecture of the stable buildings was adapted to the track width, height and turning circle of this machine. It was helpful that the wheelbase and track width of the implement carrier can be varied as with the RS08.
The VEB agricultural machinery "Red Banner" Döbeln who made already Attachments for the RS09 in the 1950s, produced from 1957 to jib crane T 157 , with various assemblies RS09 of - mainly referred to as drive axle motor-gear unit of the drive block - were used. The design development that leads to the T 157/2 “Up” universal loader is also optically similar in terms of drive to the implement carrier.
Based on the RS09, the forklift DFG1 RS09 and the narrow-gauge RS 56 tractor, built purely as a maintenance machine, were built in the early 1960s. As a special version, the RS 09 was also available as a portal equipment carrier.
