I think the term "friend" is overly used. A co-worker got upset with me when she realized that I do not call her, or anyone else I work with, "friend." I simply stated that its not a negative thing. Do we hang out outside of work? Do you call or text me after hours? Do you talk about your personal life with me? All answers were, no.
I have different categories of people in my life:
Strangers, acquaintances, co-workers, neighbors, friends, family.
Calling someone my "friend" is something special to me. My friends are people who support me no matter what. I could call them to bail me out of jail and they wouldn't even hesitate. We hang out on a regular basis, have similar hobbies and interests, and our families get together just about as often as we do. They are completely welcome in my life, I would trust them with my life. I need both hands to count how many friends I have, but not a third.
So, to answer the thread question: Out of my friends, 3 do not have tractors. Not even a riding lawn mower! Two live in town, one in a down town condo! They have no use for a tractor and are happy in their living environments... just so long as they can come out to my place for some fresh air from time to time.

The other guy, he has an ATV he uses to plow the driveway of snow, a walk behind tiller for the garden, and that's about it. His property is pretty simple. Though I have hauled my tractor to his place a few times to do some work. 3 times since 2018. That's not enough to justify a tractor purchase.
