I'm looking at purchasing a used skid steer for use on the farm. I have found two that I may go have a look at. First is a Gehl 4640 with around 1600hrs and the next one is a Case 1845c with I think 3000hrs. Gehl priced at 18k, Case at 17900. I have never owned a skid steer so any and all advice would be helpful.
