I'd like to swap a 12v cummins engine that i already have into a 1850 and wondered what were some of the weak points in the transmissions and rearends. The motor is estimated around 900-1000hp (im taking it out of my modified dodge pulling truck). I dont know anything about these tractors but have seen tractors with the swap and thought it would make a neat pulling tractor if i can get it to hold the power. I'd appreciate any idea's or suggestions on this, like i said i dont know anything about the tractors just thought it would make a neat pulling tractor since i already have the motor.

Thanks, Brett
