Kuhn vs kverneland four furrow plough

And is the turnover angle of the plough correct?

Doesn't take much to make the plough crab if the landslides aren't perpendicular to the furrow bottom
Yes turn over is perpendicular. Ploughs running 90 degrees to the ground.
I think I’ll test it with the check chains tight so that the plough can’t pull to either side.

do you guys run your skimmers in line with the points, or are the set slightly towards to unploughed land?
because I’ve also thought that perhaps the tractor isn’t sitting in the furrow quite as well as it should as the furrow wall isn’t a perfect cut. I’ve adjusted the coulters but obviously since the landslide isn’t running straight, it isn’t leaving a smooth wall of the furrow.
do any of you guys run furrow swords? To get a better cut

The way that's running in the furrow with a gap at rear of the landslide it should have the top link pulled away towards the unploughed ground?

Have you tried putting it back to whatever width it was at before to see if it works at a different width
 
Right,while theres a few kuhn ploughmen here

Ploughing right handed ploughs perfect,pulls straight

Left handed pulls to the furrows🤦‍♂️
I'm running out of ideas wondering if any of you guys can point to probably something simple I've missed🤦‍♂️

Definitely same depth rear fur each way? The clamp for the wheel to the beam became a tiny bit loose on mine. Looked at everything before going back to measuring the furrow depth. There was a good half inch difference, and yes, it pulled beautifully straight one way, and pulled to the ploughing the other. Never told anybody I'd missed something so simple, so managed to cover my embarrassment..... Oh wait, bugger....

My plough needs one turnover screw to be a turn or two less than the other for it to follow straight both directions. Never have found why, and there's no obvious difference to the lean angle, but the landslides wear slightly tapered on the side that doesn't pull straight unless the stops are adjusted different lengths.

Is your tractor linkage worn unevenly? I'd one years ago that needed the right arm shorter than the left. Again I never got totally to the bottom of where the wear was, but put it down to many thousand acres cutting with a 10 foot side mower conditioner.

Are all the skimmers at the same offset from the points? The skimmer legs can be in line with the landslide, or turned to cut wider. There's also a grub on each leg for fine adjustment. It might pull offset if one side is cutting more than the other?

Yes 7 inch deep front and rear both ways
I moved the depth wheel back last week but I'll check the in the morning 👍

I can understand the wing adjuster not being identical nothing is perfect

I measured the link arms this morning and set them both identical, tyres both identical
I put the cross shaft in the arms and stood back to look,the linkage is perfect to the tractor axle

All skims are set the same

ive had a play in a different field this morning, its somewhere near,seems better out wide on 18s
Are you certain that every mould board is throwing out the same width? Could it be you've one needing the stay adjusted, but not so obvious when they're throwing more soil at 18"?
