You absolutely don’t need anything this big to tow most of that stuff, most farmers I know do fine with a ute half as tall. The only case I can think of where one of these gigantic US-sized SUVs could be necessary is with an equally gigantic caravan.
Yes, a tiny 15 HP tractor from the 1950’s can tow a big trailer around a farm no problem. What it can’t do is tow it at much more than 2 mph. Owners of these trucks can tow a 20 foot boat down the freeway at 80 mph. Now whether or not they use them for loads like that (they rarely do) is another issue.
They aren’t talking about tractors. Ute is what Australians and New Zealanders call pickups.
So smaller pickups can do much of the same as the large.
My brother’s Ford Ranger got pancaked because he was pulling his new boat that was too big for the truck and couldn’t stop in time at a traffic light before ramming the car in front of him.
