I "drive" a 3010 diesel.
It handles well at 22 mph...... and also gets nearly 20 mpg.
I didn't want to hijack the thread, as the original post said most of what needs be said, and well..... but I wholly concur that a tractor is FAR more sensible an investment than a car, especially per this ragtag assembly of forum posters.
I am well known in these parts, but not for having my big wheels parked at the local bar.
Jim, these tires do wear a bit more on the highway.
I'm finding that four or five years of service is to be expected when driving pavement 70% of the time.
The upside is, my tires never blow for weather cracks.

They give out for
wear.
Dollar for dollar, all uses considered, the tires are not that expensive for what they accomplish. For me, it's the incidentals of getting the bugs ironed out of an older tractor.
Obviously, one of the big benefits of a 61 vintage tractor over most cars and trucks is the ease of maintenance and repair. I enjoy the mechanic work, just don't like a bent rocker arm or a burst hydraulic line 20 miles from home.
