I've never bought a pressure washer, so I'm all ears for suggestions. My goal is to wash my saw logs before trying to cut them. With all the clay and gravel in our area I'm dulling a lot of chains trying to cut off the bark slabs to make a cant. Seriously, yesterday I had to sharpen after every cut before I got the bark off the log. I have no idea what to look for in a washer and don't really know how to go about searching.
