My 7740 is different, lift a turnbuckle on the drop arm and turn. have it on both sides.While standing at the back of the 6640 when removing the transport pin on the tedder I happened to pass my view past the lift arm on the right side which has the adjuster levelling box at the bottom for setting the right lift arm height. The box is screwed together by a 45mm threaded cap which carries the full weight of the lift arm. What my eye caught was that the cap had slipped out of its threaded housing on one side by a few threads and I decided to investigate. Sure enough the locating grubscrew that prevented the cap from unscrewing had come loose and the threads had become damaged. New parts ordered but wasnt impressed on how fine the threads on the cap were, same with the original toplink which got loose quickly. Lucky for me this didnt part company with a big load on board while on the road.

Dammd ingenious to be fair!

It’d be a better job too, the adjuster gear i have is fiddly enough.My 7740 is different, lift a turnbuckle on the drop arm and turn. have it on both sides.
Around €700! Looking at other options now...What sort of money is that levelling arm new ? Genuine?
Put it back together and weld itAround €700! Looking at other options now...
I have it back together as threads weren't totally gone, itll keep me tedding for a few days.Put it back together and weld it

Welding not an option as its cast iron!
I wont be using it on the road at all until I get one. I refitted it squarely last night and it never budged during todays tedding session but I need to replace it. Dealer said he never had to sell one before as they dont wear there, just unlucky mine came loose. Hes going to check for me a breaker in the UK who they have used and is confident the part will be good.Ouch. I had a feeling it would be dear , hence my question.
Something like this ?

You want to take it very handy on the road. If it lets go , it could make bits of your tedder.
I saw both a drum mower and a fertiliser spreader written off , when top link let go.
There were a lot of International tractors around here. The 74/84/85 series had very light drop arms. Many people made a solid drop arm , using 2 pieces of 2" x 3/8 flat welded together , a piece welded at each side at the bottom , with a hole for pin through lift arm , and 2 pieces welded on the flat at top with holes for the knuckle pin at the top.
Ouch. I had a feeling it would be dear , hence my question.

Thought cast could be welded with the right set up and rods?I have it back together as threads weren't totally gone, itll keep me tedding for a few days.

Yes but not structurally strong enough. You'd weld a thermostat housing or a non load bearing plate but not something carrying several tons.Thought cast could be welded with the right set up and rods?
I remember Dad saying they had issues with a Nash and poor linkage.Ouch. I had a feeling it would be dear , hence my question.

I was thinking that exact same thing, and some threadlock might sort it. Then again you'd be thinking about it while on the road with 1000lts of water in the sprayer or with the 3 furrow reversible on. Itd be fine for a loader tractor or light duty work. Will have to go hunting some dark night and swap with someone elses!I’d say you still have serious grip on that but I wonder if you drilled 3 longer grub screws into it so it couldn’t edge out on any side?
Dust sticks to grease and turns into grinding paste.The slides on the rods for pickup hitch could do with some grease!!!
I'd still be wary of it, as said before if the item on the lift arms crashed to the ground onto a car or worse still a person it'd make a new part cheap. And you'd then still have to buy it. I should have a price for a used part next week, for the moment its holding well. Ploughing will be in October so no panic yet.I think you can weld it but you'll have to pre heat cast slowly and after welding let it cool slowly. Depending on size of piece it could take hours.
I just have an ordinary bolt and nut through my adaptor, it’s really only there to stop it sliding off.This setup isnt acceptable.
With the wood chipper removed I have this adapter sticking out, wayyy too big to put the cover on.
I'll have to remove it but its secured with a roll pin, not really designed for taking on and off.
