While you're waiting for the ground to dry, take Dawico's advice and ask around a bit. It might be cheaper to hire someone to do the work than rent a skid steer. If you've never driven one, there's a learning curve. It's not very steep, but it can get expensive if you're renting and you don't want the machine to sit idle while you're renting it. For perspective, a neighbor of mine is a builder who used to own a skid steer but rented one for a week to do some work on his property. He only needed it for a couple days so to recoup some of his cost he put a notice on the neighborhood facebook page for anyone who might need work done. I hired him to take out about 10 stumps and relocate some very large rocks. He charged $50 per hour, which he reminded me was a good deal. He knew how to run it and got the work done in 4 hours. Yes, I could have rented the skid steer and I've driven them, but wouldn't have had time during the week to use it and it would have taken me longer to do the same job.
For the record, I bought a 32 hp JD tractor for my 6 acres and use it a lot.
