Programmers are responsible for programming.
I'd recommend looking at makers of the sort of equipment you have an interest in making and see what openings they have. There are plenty of YouTube videos showing demonstrations and end users of field equipment - planting, fertilizing, irrigation, pest control, harvesting, and all the agriculture adjacent activities.
There are also all the non-field equipment, such as used for feeding and milking cows, managing chickens.
I recommend you find something you like.
