Guess I'm extreme
A lot of my hogging is done by backing down over a creek/ditch bank. The cutter drops down and then when I come back up the top link would then bind up. I found I was actually compressing the top link into the back of the tractor. Got lucky, only think I broke was a few lynch pins. Went to this setup and haven't broken anything since.
One word of warning. I have caught the front of the mower on stuff and caused the back of the mower to raise up a couple of times. Scares you at first especially when it slams back down. I try to make sure to keep the front of the mower up so it doesn't catch the ground, but once in awhile.....
