Why does farming equipment require such low horsepower compared to your average car?

This question seems to miss the understanding that horsepower is a measure of work done- that is, some amount of mass multiplied by some amount of distance all divided by some amount of time. (Horsepower a a unit is kinda weird like most US customary units, so you would have to pay around with the numbers a bunch to get mass, distance, and time out of the force, rotational speed, and constant that make up this particular unit)
In an application where your work gets done at a slow speed and doesn’t need to change that speed significantly or quickly like towing or farming, a better unit of measurement to use would be in units of force. How much force can this machine apply to this load. For things that rotate, the force is torque.
Horsepower is calculated from torque and rpm. The equation is (torque × rpm)/5252. If all the torque needed is generated at a very low rpm, as is the case with large diesel engines, the horsepower is going to come out small.

First thing is the premise of the question. cars don’t require that much horsepower. We like and want that much horsepower.
But horsepower is only one part of the equation when it comes to any vehicle, or piece of equipment. The engine usually drives a transmission of some kind, or a pump for hydraulics, etc.
My daily driver has an excess of 300 horsepower. I have a military truck that weighs 8,500 pounds, that has a whopping 92 horsepower. I also have a tractor with a front end loader, that’s 38 horsepower, And it’ll drag both of them around the yard. It’s all about application.

Ive been operating the new cat 982(loader) lately and those things have balls.. to get that much weight, loaded or not, moving so quickly, is impressive.

Horsepower is a function of torque and speed. Since farming equipment generally requires higher torque & lower speeds, horsepower won’t be high. I could go in more depth, but other people already covered it fairly well.

Id like to know what equipment you’re looking at, a John Deere S 980 has like a 900hp MTU engine. The new Nexat has an 1100 hp engine. Some silage choppers have 11-1200 hp engines. A typical 4wd modern tractor is 380-600 hp with 900-2000 lb-ft of torque.
