I would keep the little tractor if you can possibly swing the payments. I would have been in a world of hurt several times with tractors getting stuck in sink holes or backfilled areas. Just a couple days ago, I had to get my LS to pull out the Kubota B26 that went down in a stump hole. I couldn't even lift it out with the back hoe or FEL bucket but the 7010 sucked it out on idle without a grunt. Without my second tractor I would have been looking for trees and timbers to put under the stabilizer to jack it up then more trees to put under the rear tires to roll it out on. Then I would have had to clean it all up. As it was, just pulled it out, then ran the FEL over the ruts to smooth them out. I may have to put some rocks in that hole to make it hard enough to run over.
Again congratulations on your BIG tractor. I need to line up my two for a photo op.
