I heard you were considering a tractor to feed with. There are a lot of problems with that that offset the reliability of your team. You have to build a heated house for it or hydrolics won't work or it won't start when it's cold. It'll get stuck in a foot of snow and won't go on ice. It's expensive to buy fuel for it and to heat the house you have to build for it. Besides these days parts don't work or fit because each one is made in a different country and all seem to be a few thousands off. If there ever is a trade war parts will be none existant. I find a peace of mind having a system you can rely on. If I was you I wouldn't sell the team. At least then you'd have a back up and you could use them to pull the tractor out when it gets stuck
