MF weak drop arms

[Hard at work]

I have seen several fail . Worst was when a loaded sprayer was on rear linkage , sprayer was written off but usually when ploughing ask you local dealer how many they’ve sold you’ll get an eye opener

Id say 9.9/times outta 10 its the operator that's at fault regarding tractor linkage just suddenly breaking like what your on about.
There is lads on here do far more work on same linkage as i have on current & previous masseys here, but hand on heart
ive never had any issues.
28 years of 6cyl masseys from 3080 right thru to 7499 had most of the models inbetween.
All have had new Top-links mind, not cause they broke neither, they were getting slack & always change them at that point.
5 fr plough is twice as safe on 7499 than my standard lift cap 6480 which has it on its limits
The 7499 uses the much beefer Top-Link also now.
I think your making a lot of noise for nothing.

Have a 6f auto reset, hydraulic vari width plough with 3m packomat slung on the back of our MF and never had an issue. Carry plough on road.

be a fair size massey tho upfront? my 7499 would iam sure carry a 6fr with no issues.
but i have it on 5 & its just the right tractor for it.
Toplink gets far more stress than the lower links anyways.

I’ve bought a 5 leg auto reset discaerator (about 2.5 ton) this summer to go behind my 6616 d6. I’d be more concerned about top links and buying quality linkage balls, chewed through 2 cheap top link 3/3 balls within 50 acres of spud land. Bought a genuine agco one,did another 150 odd acres without a scratch on it.
I try to remember to dump the oil pressure out the reset rams when on the road, hopefully limiting the damage when the legs smack the tarmac

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.

 

[Cowabunga]

Since these are standard CBM parts, it is possible that these could be changed for knuckle type parts if you delved into their parts inventory.

If the plough is a five furrow, heavy type with all the toys, I'd venture to suggest that the 7718 is not sufficiently heavily built to handle it and that serious consideration should be given to buying a larger chassis model instead. A 7720S would be a far stronger machine all through.

I have a 6490 already, looking at replacing a Deutz 4cyl 6160.4 with a MF 6718S.
The plough is a 4F with a mounted furrow press, but would be used too much on this tractor, it is mainly the mounted disc harrow is my biggest concern.

It should handle a mounted folding 16ft disc harrow no problem. I had [still have] a mounted folding 12ft disc harrow behind a MF590 for goodness' sake and the only issue I had was that it stretched the check chains and bent the pins in the triangular link in the chains. I believe it may have ripped the ear off the anchor plate on the axle side one side of the chain as well, but it was a long time ago. Certainly no other issue with the links. It weighed a ton and a bit.

Current heaviest implement I have is the fertiliser spreader, which weighs 3.8 tons when full. That needs a large frame tractor on my steep land. I would limit it to a 2.4 ton cargo if fitted to a 7718, no doubt about it.

Check the tractor's gross weight limit, including any implement, and deduct its bare weight, not forgetting to add the front end weights, to see how much weight is sensible to carry on its links. You may be surprised at how little you should carry on the links.

I was struggling to see the issue so had a look at my selection.

I thought these..

were pretty standard issue, I've never heard of them failing. my old 6260 has the same and she's done all the heavy lifting work since her arrival. But after looking a bit further they do straight ones too

does that look stronger? I'm still unsure

 

[Lofty1984]

Have you seen how thin they are on a 215 r

 

[Farma Parma]

ive got both types here & the diff setup on the fendt backend on the 7499 which i think is a better idea anyways.
i'll get sum pics tomorrow

cant agree more here esp regarding the 5fr plough issues.
any 7618/7718 should be fine with a 5fr tho as they have the extra lift cap over the 6290/6480 lift.
but the larger framed 6485 up over & 7619/7719 up over tractors are heavier again.
Without looking at the spec on the 7499 iam guessing its about 9.6t lift or somewhere about there.
The max even a 7718 can be is about 8t again not looking at brochure.

 

[Farma Parma]

I ploughed using my Plough a 5fr KV on a 7718 4 years ago & it handled it a lot better than my 6480 did
7499 still better than both tho

 

[Farma Parma]

7718S is 8100kg rear lift in dyna-6 or 9600kg in dyna-vt
the bigger Framed masseys are a mix of 9300 or 9600kg
unless you get the 7724 or 7726 & they up things slightly to 9950kg regardless of type of Trans

I think you are worrying unnessisarily @gone

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.
