85/2 Power Steering Pivot Bolts

Hey folks - looking for some help on how to de-tension the power steering belt on an 85/2. I was following the NC944er video but my pivot bolts are somewhat different. Can anyone give me a tip on how to loosen this off? Can’t get a wrench on the front bit of the nut that’s protruding but I’m guessing that’s not correct anyhow.
