Kuhn vs kverneland four furrow plough

Aye, but what is the folding ram measurement L3 when in working position? Doesn't matter if it's a rigid link or hydraulic folding ram, distances between pivots of the parallelogram need to be correct for correct plough angle
I’ll check in the morning and let you know. I do think the problem lies with that folding ram. It almost seems like it’s not closing far enough to allow the bodies to become parallel to the tractor. Ie it’s not pulling the main beam to enough of an angle to get the correct angle of the bodies. The problem is is that its set as short as it will go. But again. I’ll check in the morning and get back to you.
thanks mate

Also while I’ve got you, have you got any tips removing the bolts that change the width of the bodies? Those once that move between the four possible holes. Because mine are constantly getting jammed and it usually comes to the point where I have to hit them out and strip the threads of off them.

Grease them. Shitloads of

Then do what I did ten years ago: Set it to 16 inch and don't adjust ever again

Just as a thought, you are definitely on 90cm point to point clearance? As looking at Dr dunc's images on the 100 clearance the bolt is in a different hole for the same furrow width, would throw everything thing miles out if they are angled wrong.

Looks like it is definitely on the short setting,the folding ram looks correct to me(no spacers for 18 inches) what about front wheel width? should be same or slightly less than rear spacing.

Just measured the distance L3 and it is set at 566 like the manual states

It’s definitely 90cm point to point and the bodies are set to the correct position for 18 inches 🤷‍♂️. It does almost look like they are angled wrong. I did try testing them in the 16 inch holes with the plough still set up at 18 inches, just to swing the bodies in the right direction. But it didn’t help at all

Iv got them aswel. They are great
I don’t suppose you’d know the answer to this. But the Massey 5713 s lifts and pulls the MM 113 4 furrow very easily. It has a lift capacity of 5 tonnes. Do you guys reckon it would lift the plough with the added fifth furrow on it ?

On my old kv manual vari width they were a pain to take in and out usually ended up with a block of wood under the and of the landslide and wiggle the plough up and down with the tractor to get them moving but you still usually damaged threads somewhere . Best left alone once set unless you break a bolt

What does each ram do on that plough? It seems to be strange setup that they're both attached to the same pin?

The outside ram was an extra,straightens the beam prior to turnover,it is teed into the turnover ram circuit so happens automatically.Expensive extra but a nice bonus on a used plough.

Ok so without studying a manual it looks like that outside 1 is too long so it's not pull the beam far enough round it was probably better at a narrower furrow width but at 18 it cznt do it ?

Yea that’s pretty much exactly the problem! The ram is simply to long to perform as it should from what I can tell.
