I'm guessing maybe you were here after some really really wet conditions which can sometimes leave those long putty like clumps that won't break up . That's always a tuff call when prepping Its usually best not to disc under those conditions , but then you have those people that think your not putting In the effort , sometimes discing isn't always the answer . We think our prep has been great this year especially with some of the tuff weather conditions this year . If you decide to come out and I hope you do look me up I'd like to meet you and get your opinion . Tks ART
