New Case IH Farm Stock in Germany

Stefan Schöler from Seppenrade, in Germany has built a completely new Case IH Farm Stock Tractor for the 3.5t / 7700lbs. Sport Class in Germany during the last winter. Stefan started with pulling around 3 years ago, on rural youth Brush Pulls with a Standard IH 1246 Tractor in his area. But that wasn´t enough for him, he decided to purchase a second IH 1246 in 2016. In the end of 2016, he started with the building of his first real Farm Stock Tractor. The original IH 1246 was completely dismanteled and the engine, the rearend, the gearbox and the clutch bell housing leftover for the Farm Stock project.
The new Pulling machine received a homemade steel wedge frame with a steel rollcage, a new homemade hydraulic power steering, a self built drawbar, homemade wheelie bars and a IH 1246 rearend. The hood on the Tractor comes from a Case IH Puma 210 and the steel sheet metal fenders are self made. Also all the sheet metal work on the hood and the chassis were made by Stefan himself. For a good grip on the German pulling tracks he bought a set of used cut Michelin 650/65R42 XM 108 tires on steel rims. The steel rims were built by Matthias Böhling of Schlunder - Metal and Pulling Parts from Groin in Germany.
The rear axle was completely dismanteled, checked and received a needle bearing diff with a stock IH 1246 ring and pinion gear. The rest of the parts like the driveshafts, the axle funnels and the planetaries are still original. However on the gearbox is not very much original anymore. The 1246 housing of the 4 speed gearbox was machined and the stock shafts with the gears were replaced by new homemade components. Stefan Schöler also has made all the calculations for the new shafts and gears for the gearbox. Also the cast iron bell housing was machined and a new Freakshow Performance centrifugal clutch with 5 discs working in it now. Because of the safety rules, the cast iron bell housing is protected by a shatter blanket. The shatter blanket is a very important part on the tractor. It protects the driver and the spectators against flying clutch parts, when the clutch should explode.
The Case IH Puma 210 is powered by 6 cylinder IH DT 358 power plant with 6l capacity on diesel fuel.
The engine has a DT 358 stock block with original IH sleeves, a IH 358 stock crankshaft with IH standard steel rods and revised steel pistons, a revised DT 358 head with a grinded camshaft, a homemade intake and exhaust manifold, a Holset HX55 turbocharger, a self built air-water Intercooler, a Bosch P diesel fuel injection pump with 16mm elements and 4 channel data logger.
Owner and driver Stefan Schöler actually wanted to compete again at the rural youth Brush Pulls, but that went a bit out of hand. This year he ran for the first time in the DTTO, but competed  because of the overweight on the Tractor outside the evaluation in the 3.5t / 7700lbs Sport class and in evaluation of the 4.5t / 9260lbs Sport class. 
Stefan has planned to compete in the German Championship again next year.
