Alright, back to the thread, sorry for the hijack, if you want a tutorial on WBTs, start another thread, I'm done hijacking the OP's thread (unless, of course, I can find my pics of the WBTs on a very large US Army base deep in the FL Everglades....). Although it has been fun, it's not fair to the OP.
Regarding backing up long hills, especially with a bushhog.
Look at these three pics; note how high the vegetation is, particularity the Poke Salad Annie (don't recall it's scientific name). In these pics, it's about 10-12' high, I was sitting in my tractor (
L4330) when I took the pics.


Basically, there is no way to realistically go backwards against that heavy and high vegetation. I can barely go up the hill forwards and only by taking a small 3-4' cuts instead of a full width 6' cut. I couldn't see crap going forward, there's no way to see anything going backwards.
BTW, that was the first time I bushogged my field after I bought the place. I first BH'd it August 2014 and it was probably 3-4 years since it was last BHd. There was a thread here on TBN about bushhogging my hills from around that time, but I can't find it right now.
