No doubt on scratching. This time of year the black dirt is hard as a rock. Easily ran B2 out of C4 gears at PTO rpms.
I had 2 main concerns which were satisfied: One was I thought it was much longer that it is (little over 6') and concerned at how much it weighed when thinking about foot-pounds hanging out there behind the 3 pt.
Length is a double edged sword with the longer the easier to get tangled in a fence on turning around and second the ft-lb thing I mentioned.
Passed both tests.
The discs are 20", the hubs are about 4" so when things soften up I ought to get at least 6" of penetration. That will be adequate.
Thanks for the help
