Mine was TSC as well. Made couple of passes in a newly cleared area before the hard stuff. Interestingly I had major pigweed right along the tracts where the cuts were made. Looked like I had seeded for it. Guess I did! Just used the existing seeds.I found a subsoiler to be a great tool for old very compressed logging decks on my heavy clay soil. With all the negatives of tillage, there are cases where the long-term good outweighs the long term bad. It is a 1 time thing and it is hugely better than a moldboard plow that turns the soil over. Once I get past that initial decompression, I stop any form of tillage.
I will admit, I got an inexpensive single shank sub-soiler from TSC and I bent it with my 45 hp tractor.
Thanks,
Jack
