Yes, I guess you could do that Leroy.
We always rolled the tractor off and then unhooked the dolly from the truck. I didn't have a jack on it. I originally built mine to be balanced, but had to scratch and claw getting up the hills on our lane. I cut the spindles off and moved them a few inches to the rear and it made it usable. It's been a long time since I've seen it. I can't remember if I traded it or loaned it out and it didn't come home. I remember that it was real easy to loan out, in fact it usually took several phone calls to figure out where it had "moved" to. I started to weld my name on it one time, then it dawned on me that some borrower could get in a wreck and right there real convenient would be my name. A lawyer's gift from heaven.
I used to make hay all over the neighborhood, and it was handy for getting equipment to the field with just one driver.
