SA 424 3 Point Stabilizer replacement?

[TnAndy]

My previous tractor was a 1998 Model 1925 New Holland (not seeing what that has to do with it) As I stated, it used the exact same system, and never bent. My feeling is the Yanmar used holes too large, leaving too little metal to withstand any compression, and/or the metal is crappy.

What exactly do you mean by "zero compliance" ? Do you mean the link must be tight and allow zero sway ? How is that possible with a hole in a link with some distance (whatever it is) from hole to hole ??? With a turnbuckle, one can tighten them to zero sway.....not possible with the pin hole type.

What I meant by zero compliance is there is nowhere for the link to compress or move if the link is put in compression. Turnbuckles can go in any direction if put in compresion.

Well, unless Yanmar is making them better than the crappy ones that came on my 410 (and maybe they quit), you're better off with the turnbuckle version if that is what you have.

I had the pin type on my previous tractor (New Hollard 1925) for 13 years and NEVER had one bend using the tractor the exact same way I used my new Yanmar......which includes using a blade in reverse, backing up a bush hog, that kind of thing....stuff you OUGHT to be able to do with a tractor and stuff not bend.

Not bent:

Bent:

The pin links would bend at a 30-45 degree angle under much pressure at all. I think they either made them out of cheap, soft metal, OR they drilled the holes for the pin too large not leaving enough metal on the outside of the hole, or a combination of the two. As I said, 13 years with a NH and never happened. Few months with Yanmar and it happened several times. Dealer replaced them under warranty, but I could see it was going to be MY problem eventually, so I started in on them, and the factory rep, and some Japanese engineers they sent out to my place, saying "SURELY you guys can do better than this" I was starting to think I've have to buy a set of New Holland links and use them !

They finally sent me a set of turnbuckle ones. and for 8 years now, they have worked just fine. I wonder if they just finally threw in the towel on the pin type.

New turn buckle type on the left, original pin type on the right, with one of the bent ones.

The turn buckle style is what came on my EX450 .
