MF weak drop arms

[Farma Parma]

Still the same stabilzers which bang side to side though which when out of work a simple pin to stop it from happening would be nice.

true but ive got a pipe made up with Cat3 balls on to hold link-arms wide apart when not in use & then just tighten turnbuckles
up against them.

7499 heavier Genuine TopLinkView attachment 747926

Probably more important to have this

i couldn't believe that size of Tractor didnt have that as standard.
Only comes on the dyna-6 gbox versions.
Bugger that i bought one & the 6480 a rep new one at the same time.
Not worth the risk i thought.

 

[Farma Parma]

The 7499 does however have CAT3 size of pin at Tractor end on factory toplink.
where as the 6480s is a smaller hole even tho it looks much the same

I snapped one of those slightly offset lift arms on my 7718 and 5f Lemken with it in the air on a headland. Gently dropped the rear wheel into the furrow and BANG. No damage, other than that lift arm done, could have been terrible on the road. Looked like it had been going for some time though.

I have what looks exactly like your top link, a standard Cat3 CBM one, from new on my 1997 NH8360. Same colour too.

The black one fitted to my 2004 7490 has a flat each side of the threaded rod at the implement end where the rotation latch sits. That must be a CBM top link as well but a different model.

Yeah sounds much the same Mr Duck
That Rod on the top to adjust it has a piece of shaped metal underneath that drops into a slot cut out thru the big threads all the way along the rear of the link it seems to do the trick.
Run Cat3 pin/ball on Plough with this now aswell

Anyone come up with a solution to the weak spot where the drop arm is cranked? Can they be replaced with a straight one?

I just don't trust them with heavy implements.
TIA.

Some I have seen are even angled at the top. This is one on a 7718, it doesn't seem to be a big issue as no one else is seeing as an issue.

Broke one in the spring time this year. Turned plough over reversed back wheel dropped into furrow bottom and bang plough hit the ground.

It is a serious design flaw that creates a stress point that will fail, it is not fit for purpose and dangerous. MF should be sued for allowing this dangerous flaw without doing anything to fix it. It is a stupid thing that badly lets down a good range of tractors and it would be easy for them to fix.

What about claas then too if your gonna sue people they use the same backend.

If there was another hole in the link arm further back toward the implement end that you could put the drop arm in this would cut the strain on the drop arms and cross shaft and the arms themselves by a hell of a lot providing that there was still enough lift range for the implement, some older tractors use to have this option

There are two holes

This happened to me this year

so has a 7480

 

[Speedstar]

this is all so a common problem on MF if using a heavy plough on them or any heavy machine on the 3 point linkage.

That part had been bent beforehand through misplacing the pin through the links at some time and lowering or raising the arms [I forget which]. It is easily replaced and there really is no need to bend it in the first place. However, once damaged, it should be replaced with a new part immediately. It costs near bugger-all.

Most of MF's rear linkage parts are fairly standard off-the-shelf items from the CBM company. Including this particular rear linkage.

Oh right. I probably did it myself then somehow, I lift the arms up and put the pin under the arm to keep them up and away from the pto shaft on bedder and baler etc. Yes a quick easy fix. Got a fright though

Yes, that is exactly what causes that part to bend. No flies on me
