My mx shop has the older version of this... the "air horse" based on a Wheel Horse mower. Works quite well, although it's not very fast.Air Deere. These are are quite nifty. https://tiffinaire.com/aircraft-tugs/
I’d suggest this, but with a gas cart. Electric Is nice, but not for all day, everyday use. Or when operated by idiots…Local fbo does this for the flight school but with archers. They use an older jd gator retrofitted with car tires. I assume they did the math and found that to be the best balance of speed vs cost.
I would be inclined to try a 48v golf cart. That's what I use as a tug and I love it. Very maneuverable, pretty cheap, and useful as a runabout. I've made several trips to the mx shop, which is about a half mile, without a charge and never seen the charge gauge move. It's also light enough to push/pull that last inch or two.
I'm not convinced the centrifugal clutch in a gas cart would hold up very long. It would also be jerky, which is my complaint about an atv/utv, although as I mentioned above my fbo seems to get along fine.I’d suggest this, but with a gas cart.

This, with Brackett tow bar and hitch on the front.Used ATV with appropriate hitch.
That'd be nice, for sure, but the OP did mention budget considerations.A Lektro tug. No towbar needed, fast and efficient.
