The Ford 8N was largely designed around pulling a 2-14 plow, and a lot of them did just that back in the day. Plowing is why the 3 point hitch was originally designed, before that, if a plow hit a stump or a tough patch of soil, the front wheels were coming off the ground.
The first tractor that was marketed for landscaping tasks and other not-strictly-ag purposes was the International Cub. The Ford N series were absolutely marketed as regular ag tractors and people used them as such.
