It looks like they just put bolts in where the ball type knuckles would normally be?That is an odd plough, spring loaded furrows with the springs removed, I never realised that the subsoiler legs were fitted in that position.
They just used a blanking plate at the end of the connecting rod, where the springs usually connect, I have never seen one like it before.It looks like they just put bolts in where the ball type knuckles would normally be?
I wonder what the reason for that is. Perhaps they wanted to put on the subsoiler legs but that was causing the spring loaded furrows to lift too much when in work?
Serious gear, that person has a few videos of that outfit on YouTube. In fairness it’s a fairly intensive operation for big scale, normally that scale would be min till and fast trailed drills, whereas they are plough/press, power harrow, fertiliser down the spout (looked dark like Phosphorus), jcb for picking stones. The ground had already been tilled too (probably rape stubble for slug control).
