At the first post, this wasn't clear. Torque in first post was engine torque? I believe farmers usually use pto torque rather than engine torque which is looked at by car owners.. In general, everybody (car, tractor, etc owners) takes HP as engine HP and this is normal as it is rated power that engine machine can give from combustion in cylinders in which pistons follow linear motion. We mention torque only about rotating parts from crankshaft to gears to transmission shaft to pto (for tractors) at end side. So, when engine torque is mentioned, it is the torque at the crankshaft actually, measured torque after energy or power losses in combustion and at bearings of crankshaft. When there is no pto, like in cars, it is usual to talk about engine torque which is actually crankshaft torque. At any rotating part, we can mention hp too as it is torque and speed multiplication. Since hp, usually engine hp, is constant for an engine, in general, engine hp is meant when hp is mentioned.. In cars, usually torque is not mentioned, but its max speed (unless it is off-road car.) So, depending of application of engine/vehicle, torque at different points become important and in farm field, it is pto torque is important if attachment is driven by pto.. So, I got the torque in first post as torque at pto. If not, if it was engine torques which are equal while hps are different, then, it is another story, related to engine itself, more about crankshaft, flywheel speed and tyre wheels. In this case, bigger hp vehicle will run faster or vehicle itself is made heavier to spend extra hp to carry its extra weight. Anyway, I believe farmers usually use pto torque rather than engine or crankshaft or flywheel torque which is more important for, say, off-road cars.
PS: Farmers here in Turkey usually use only power, HP when talking about tractors. I have seen here on this forum mostly US farmers participate that the torque is frequently in discussions. While including torque in talks causes confusions, it is a reason for progressing in learning and clarifications.
