I'm not exactly sure what you are considering or how you plan to set it up. How you would have to manage it depends on how many chickens you have, your climate, and how the grass and weeds grow.
I've used just a tractor. Those are a commitment. You have to be around to move them every day or two. If you need to go to a funeral, wedding, or something like that, you need someone you can depend in to move them for you. I don't use a tractor anymore.
I currently use electric netting from Premier. I have it set up so the chickens can go out of the coop into the area protected by the netting. It depends on how fast the grass and weeds grow. Sometimes I have to move it every couple of weeks. Sometimes I can go months. Snow can be a problem too. The problem is that the grass and weeds grow up around it and ground it out, especially when they get wet. A weed eater will destroy the netting. I physically take up the netting, mow where I want it to go, and put it back up. The gate part is fixed but I can vary exactly how I run the netting to get new grass.
I don't know what area you are looking at or how it would be set up. I'd suggest you consider building a coop. Make it so you can move it if you wish. Mine's not movable but you are in a different situation than me.
Put your electric netting up around the coop, running it from a door from the coop that you can go through and the chickens can go through. When you are ready to move the netting or the coop, lock the chickens in the coop. It should take you less than two hours to take the netting down, mow, and put it back up. You can put it back up in the same spot or move both netting and coop.
One problem you might have is the gate to get into the netting area and/or coop. The way I get around that is to have a second door on the coop that I can go through without bothering with the netting. But that creates another problem. Climbing predators can go over my coop and come down in the protected area. The way I handle that is to lock the chickens in the coop at night. It's not a perfect solution but I haven't lost any in the year I've been doing it this way.
