From Hojer in Denmark, the Lille Bjorn Pulling Team around Lasse and Dieter Bjorn have built a completely new Ursus tractor for the 7700lbs / 3.5t limited super stock class on component basic during the last winter. After many years in the 4.5t / 9450lbs fram stock class with an Ursus 1201, Dieter and Lasse sold the tractor at the end of 2018. The ride had a turbocharged 6 cylinder Ursus engine with an 8.3l displacement and 3200rpm on diesel fuel. After the farm stock was sold, the Danish team decided to try something new with more horsepower this time. After some thinking and brainstorming, diesel or methanol, farm stock or limited super stock, Lasse and Dieter decided to build a new Ursus limited super stock machine on methanol. Another point was to make the switch into the new limited super stock class, the alky burner tractors are cheaper to manage and the wear is not so high during the season like on a pro stock or a top farm stock tractor.
In the fall of 2018, the team started with the construction of the new machine. The new component limited super stock got a completely new Strenx 700 wedge frame with a newly built chrome-moly roll cage (ROP), new homemade wheelie bars, a Kirkey Racing driver seat, a homemade front axle with hydraulic steering, a Scania 81 semi truck rear end and a newly constructed drawbar.
The Strenx wedge frame and the Scania 81 rear end with the new drawbar were built by the Hvilsom Pulling Team from Hobro in Denmark. Berrie Boer of the Screamin' Bobcat Pulling Team from Ijsselmuiden in the Netherlands has constructed and built the new 3 bar chrome-moly roll cage for the new Tractor.
The new Ursus 1201 hood and the fenders are homemade and were built off steel sheet metal. The hood isn't original on the tractor, it's a copy of the 1201, the team did this new hood wider and higher than the original one. Also, the rest of the sheet metal work around the tractor was done by the team himself in their workshop.
A little bit history about the Ursus company: Ursus is the name of a traditional polish company from Warschau, which produced agricultural machinery and tractors. After the bankruptcy in 2011, the ZP Ursus SA company was taken over by the Polish group Pol-Mot Holding from Lublin. The
Pol-Mot Holding continues to sell tractors and agricultural machinery under the Ursus brand.

The Scania rear end of the component limited super stock was shortened and received a stock Scania 81 center section with an improved Scania 81 differential, a stock ring and pinion gear, new custom built half shafts, aluminium planetaries carrier housing with Hanomag planetaries and new billet aluminium Engler Machine & Tool brake calipers from the USA with new steel brake rotors.
The improved diff got a new better custom built diff cross with needle bearing from the John Deere Pulling Team in Thy, Denmark. The completely rear end was built together by the Hvilsom Pulling Team too.
Also completely new on the Ursus tractor is the driveline. The newly built driveline has a Profab 4 speed transmission with a homemade steel driveshaft between the transmission and the clutch, and 11" inch centrifugal clutch with 4 discs and a billet aluminum flywheel. The centrifugal clutch was manufactured by the Bukke Bruse Pulling Team from Batum in Denmark and is protected by a Browell steel bell housing.
The rear wheels on the new ride are a set of new homemade steel rims with new cut 24.5-32 Pro Puller tires from the USA. The new tires were purchased and cut by the John Deere Pulling Team in Thy.
The new Lille Bjorn Limited Super Stock is powered by a newly built turbocharged 6 cylinder Ursus 1201 engine with an 8.3l / 510cui displacement on methanol fuel. The original 1201 power plant on diesel fuel in the stock tractor made around 112 hp. After the transformation to methanol and a lots of other changes, the Polish engine should make around between 1500hp - 2000hp.

The power plant received a machined stock Ursus 1201 engine block with Darton sleeves, a new billet steel crankshaft of the company called ''Nuyts'' from Belgium, new CNC-milled billet steel rods from the John Deere Pulling Team with new GMS (Gene's Machine Shop) billet aluminium pistons, a revised Ursus 1201 cylinder head with new Inconel valves and stronger valve springs, a billet VSP (Veldhuizen Special Product) steel camshaft, a Holset HX82 turbocharger with a 102mm air restrictor, a homemade intake and exhaust manifold, a Aviaid 3 stage oil pump, a homemade stainless steel oil pan, a homemade sheet metal fuel tank, a VSP methanol injection system with a Waterman fuel pump, a MSD 8 Dual Coil ignition and a RPM Performance data logger.
After the tractor was almost completely done, the Dieter and Lasse Bjorn went to Willem Veldhuizen with the limited super stock at the beginning of April. Willem built up the new fuel system and the ignition system for the Ursus in his workshop in Loosdrecht, the Netherlands.
The first hooks in front of the sled with the new component tractor were pretty good so far. After the first pulls in Denmark, the Danish team is very satisfied with the new limited super stock and looking forward to having a nice competition against Soren Lüchan Hansen´s John Deere machine called ''Never Done New'' in 2019.
The Dieter and Lasse Bjorn will compete with their new Ursus component limited super stock in the Danish Championship and maybe on some events outside of Denmark this season.
