Are you not wanting one that attaches to a 3 point because of the price or you dont have a tractor? I, myself, have a bad back and if I can get my machine to do most of the heavy work, I'll go that route.
I'd be wondering about pulling that weight and keeping the fence roll tight enough. Do you have anything else to pull a small trailer with? LT, GT, ATV, etc.? If so, you might be able to adapt a small, low trailer like a two wheel car towing dolly.
Eddie - I don't want to be a turd in your oatmeal but - you don't expect a four foot high mesh fence to stop a coyote, do you? I've witnessed several climb right up and over an eight foot high deer fence. The deer fence was HD 4" mesh.
In the past I've used a hand truck to get the wire where I want it. I was thinking that if I had something with a pole in the middle of the wire to keep it in place, that would be even better.
I'm also considering a dedicated trailer that I can pull it behind my Mule or even my truck. I saw a few that people have built and it looks simple enough.
Another options is to buy a quick attach plate and weld up something that will do all the lifting, and then drive backwards to unroll it.
