You can use a wheeler, but you first have to put the posts in. Next, you will string it on the way back. The following step is to ride along and drop the wire on the takedown. Then you'll pull posts as you go until you reach the end. Then, you'll unhook it, go back to the reel and start reeling. You can walk towards it as you reel until it feeds towards you if it's too long. You can try with a bobbin for multiple fences. Yet, the bobbin is hard to swap on geared reels.
