Getting hitched...

I have to build the parts that connect the lift arms to the drag links on my tractor. Currently these are connected by heavy chains.

Questions...
1. What are these parts called?
1b. What are they called in Finnish?
2. How long should they be approximately?
3. How much adjustment should I build in to them?
4. I have a supply of 1" square section tube that has 4mm walls. Will this be strong enough?
5. For the adjustable side I thought to include a section of 30mm threaded rod, with nut welded to the said 1" tube (exact design is in my head). Is this likely to be strong enough?

This is for the Fordson ASP (A rare variant of the 50's Major Diesel!)

PS. At last I've managed a Fordson post, without a single mention of sheep, or horse-ploughs!

You could possibly make these items from the materials you describe however the flexible balls at each end of the linkage arms might be a problem and the linkage on the tractor when traveling over the ground can be subject to forces of nearly 10 tons when an implement bounces. In other words, visit your local scrap dealer and see what he has as far as Ford link arms are concerned. Don't bodge. For safetys sake.

Do you know a company over in Finland called Juko. They make agricultural implements. I work with their agent in England. This may be of some use as far as parts are concerned.

Thanks. OK, I won't try and make them, unless I get desperate, in which case I shall make sure I do a really strong job. The flexible balls aren't too much of a problem because they are available as spare parts (the ball, socket, and a short stub to weld) from the local farm shop. While we are on the subject, someone gave me an old top link yesterday, but it's category 3. That's too big, isn't it?

I do need to find a breakers' yard anyway, I need the part where the top link fixes to the tractor as well as the bits you know about already. At the moment the seat for the backhoe bolts on here, as well as to the casting down by the pto shaft. At present this (seat and support)is held on by a selection of studs, nuts and bolts. Any idea what the original bolt sizes were? Was there anything that bolted to the back of the tractor in the region of the pto? I can't see what could have been bolted here originally. When I unbolt the seat from here, will the axle oil come out, or are these blind holes in the casting?

Yes, Brian, I have heard of Juko, I believe they are a subsidiary of Kongskilde(?), and they are on the other side of Finland (I'm in the South East, Southern Carelia).

Cheers for now

PS. Couldn't borrow that horse harrow, the farmer thought I was a bit daft. He did very kindly offer me the use of his tractor rotary tiller and spring tyne harrow though, but I think that I don't have possibilities to fix the hitch in good time this year.
