I do the same thing with my oil filters... I find that practice keeps me on track better. This was last pic of this one, as I had enuff & it was sold & waiting for new owner coming.
Knobs aren't really a substitute for power steering. The mechanical advantage on old non-power steering tractors resulted in more lock-to-lock turns and the knob was just a way of compensating for that when the tractor is moving. They don't do anything for you if the tractor isn't in motion whereas power steering's biggest advantage is when you're stopped. True, but you can really whip it around in motion. And you can still turn it stopped, but not as easily obviously.
