Most diesels make low end torque and most gas engines make high end power because that's what their designers intended them to do, not because there in anything inherent in one or the other that dictates that result. Cam profile/duration and stroke length are largely what dictates engine breathing, thus it's torque curve.
If you were to root out the nebraska test results for the Ford 3000 and 5000 tractors in both the gasoline and diesel versions using the 175 cid and 233 cid engines respectively I believe you'll find that they have almost identical curves... much to the point that the profiles are the same excepting that the spark engine will probably achieve peak torque at 100-150 rpm faster than the diesel. This will result in the spark engine being a bit prouder on the top end because the torque rise was basically identical to the diesel. Again... SAME cam shaft in both. Same lift. Same duration. Same stroke and displacement.

It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
