I have not measured it. I will be measuring the narrow distance this weekend though. I just got it tilled up today & need to set the distance in the back closer to the barns. The width isn't something I got to choose. It's the space between the driveway & a line of little trees. The trees are in a "mitigated" area because when the house was built by the previous owners, they ran the driveway through a small area of wetlands, so the county made them plant trees. I am just thrilled to have a flat contained area & really excited for fencing it in with rails as soon as we can afford it. We plan to let that be our winter area because it is drier than the rest of the field area. I don't want them to be out there ripping it up when its all soft & saturated. We live on peat, so it grows things really well, its really dense & springy, but when its wet its easy to damage.
We plan to section off 2 smaller pens around the shelter so I can split the horses sometimes & not always have them turned out together. They are mother/son & son can get pretty crazy when mom isn't there for him to pick on.
I have pictures of the arena before/after Tilling & will post them when I can. Unfortunately this forum doesn't allow me to post from my phone, which is vast majority of my internet access Posted via Mobile Device
