I can tell you from experience that they do not work well in that....even when they dry up to the point you can pull through easy that danged grass stays in huge clumps and you just get a mess you need to clean out of the implement(box blade or scraper) and deeper ruts as well from pulling out the root masses/mats that essentially keep your machine afloat in that crud.
What I need to do is get that part the trail ditched so the water runs off to the side. Right now it just runs to the trail ruts and sits there.
No, I have not. I usually use my 6 foot rototiller for that. However, I may try using the scraper's scarifers to pull and loosen up roots before I till on new plots.
