The new Koljatti 3

The Karhukopla Pulling Team from Finland have built a new 4.5t / 9900lbs. Farm Stock Tractor during the winter of 2016 / 2017.
The new Farm Stock received a homemade Domex 650 wedge frame with a homemade chrome-moly Rollcage and a Ford TW25 rearend. The new Ford 9000 aluminium hood on the Tractor is homemade. The fenders are orginal John Deere fenders. The Ford TW 25 rear axle has a Stock TW 25 differential with special built gears, a special made ring and pinion gear, special built shafts and Ford TW25 stock planetary carrier housing and planetaries. Also the gearbox housing is original of a Ford TW25 and has 2 forward and 1 reverse gear. The gears and the shafts in the gearbox are special manufactured. All the gears and shafts were built by Kaarlo Finnilä from Finland. The Ford bell housing received a homemade steel liner and Christer Örn of Eagle clutches from Finland have built the 11" inch centrifugal clutch with 4 discs. The clutch also got a homemade steel fly wheel. The Finnish Team bought for their newly rebuilt Farm Stock a set of polished aluminium rims with new cut 24.5x32" Firestone Puller 2000 HP tires.
The new Ford 9000 Tractor is powered by a 6 cylinder New Holland Powerstar power plant on diesel fuel. The power plant has a modified New Holland engine block with homemade sleeves, a revised New Holland Powerstar cylinderhead (dry head) with a billet camshaft from Jan Burgraaf (New Generation Pulling Team), 56mm intake and 51mm exhaust valves, new stronger valve springs, a original Powerstar crank, special made steel rods and billet pistons, a selfmade intake and exhaust manifold, a Holset HX82 turbocharger, a aluminium Intercooler, a Basic data logger from the Netherlands, a Sigma fuel injection pump with 17mm elements and RSV regulator by Dikkenberg from the Netherlands.
The special made rods for the engine were built by Antti Jyräkoski from Finland.
The company Kunimek in Finland have built the billet pistons for the New Holland engine. The first season with the newly rebuilt Tractor was pretty successful for the Team. Driver Harri Laitamäki, together with his brother Jukka Laitamäki (owner of the Tractor), won the Finnish Championship and finished on a good 5th place at the 2017 European Championships in Stroe, the Netherlands.
