I'm looking at a used 843. Seems to be in good shape; minor dents, dings, surface rust. Fires right up, idles and runs really smoothly, drove very well, bucket and arm worked great. Overall, I'd say it's in great shape. The owner did tell me that there is a hydraulic leak on the left side. He couldn't find the source so he just adds more fluid. Any ideas what this could be? Worst case? I'll be using this on a 1.5 acre bluff lot that has steep hill and lots of trees. I'll be clearing the trees, digging a basement and digging out a driveway. Also, the lot is 1.1 miles from my current house. Is there any reason I shouldn't drive the bobcat from my house to the lot. I'd really rather not leave the bobcat there and I don't have a trailer for the bobcat.
