Lower 3pl arms quick hitch options?

[tractor240]

I just got sent some pics of the Walterscheid by their rep.
He said that they are cast and assembled in Germany.

AMA told me that theirs are cast in India and assembled in Italy.
Pricewise the Waltersheid are around $1000 for the kit. The hooks on their own are only slightly less so not worth it because the balls off the shelf from other suppliers may not be a good fit.

The CBM are around $600 for a pair of hooks.
The AMA is around $340 similar to above kit.
All Cat.2 prices

I have the CBM, and about the only "issue" I have is that occasionally I need to blow the chaff/grass/detritus out of them after a slashing session.

Maybe that's necessary whichever brand you use, but it's certainly not a big deal.

Just be sure you get the correct size balls. Down here, most available balls are metric (~50.0mm) and the 2" (~50.8mm) just won't fit!

Does anyone know how useful the ball guide cones are with the hooks, or do they tend to just get in the way?

Personally I can't see the need for the extendable lift arms with the hooks. Unless the tractor being fitted with the hooks, already has the extendable arms. You don't really rely on extending the arms with this system.

With the hooks, if the tractor is not exactly square with the implement, just push it a little bit with using the hooks and it's done.

Anyway, as far as ball sizes, it is as follows:

Cat 1 - 44 mm
Cat 2 - 56 mm
Cat 3 - 64 mm
Cat 4 - 85 mm

I've had 3 different types of quick hitches, frame, Pat's, and hook.

If you don't have all QH compatible implements and don't have extendable links, the Pat's are the easiest I used.

For the hooks, I made new slide in adaptors so I wouldn't have to cut up my factory ends, which worked out, since I had to switch back.

Just check your clearance of the implement around the hook. If any part loads the tip of the hook they can break!

..... they can break!

Are they AMA?

To be fair, it was a bit more than loading the tip of the hooks if I recall correctly. Weren't you extending the top link when the bottom of the hook hit the frame of the implement?

Ahh - I might have been thinking of tow ball sizes...

Regardless of whether TMGT was or wasn't abusing the hooks, it looks like those hooks have a built-in failure point where they're scalloped out on both sides at the bottom of the opening.

All three brands have the scallops. The quality of the casting is probably the potential weak point and that's likely to be what causes the considerable price difference between the three. Question is, are the Walterscheid's castings worth $400 more than the CBM and where are the CBM castings made 'cos aside from Europe, they have two factories in India and one in China.

Those indents are clearance points for the lower pins when tilting the implement left and right.

They don't really break under normal use.

I don't dispute what you've said. I simply observed that the failures occurred at the area with the smallest cross section as one would expect.

What angle are those welded?

It varies from model to model. I do not have these sitting here; they are built to what the tractor needs.

Yes, they help for connections, you don't have to be as close to centered as you do without that feature.

My dealer has asked if I want the CBM Cat.2s (small) or the 2 size.
The bar itself just before it becomes thicker for the socket is 17x60mm (A). Does anyone know where these are supposed to be cut ie before they become thicker (A) for the socket ie just plain bar or incorporating part of the thicker socket area (B)?

Should I oversize so as to get a better chance of hitting the implement target or should the hook and bar weldable area be as closely matched as possible.
CBM Cat.2s=Welding area: 32x80mm. Working length of hook:105mm, Outer Ø (mm):56mm
CBM Cat.2=Welding area: 35x100mm. Working length of hook:130mm, Outer Ø (mm):56mm

#1 for the weld-on hooks. It also helps that my implements are stored on a flat concrete floor.

Heck, I remember the shenanigans hooking up the 6' slasher to my old Fordson Super Major (before the new shed with the concrete floor came along). The procedure was to hoist the slasher from the mid-point with an endless chain dangling from the roof beams, and swing the slasher like a 500kg pendulum while trying to jam the pins in when the pendulum swung just the right amount! Ahh - the good old days...

I don’t have concrete to park implements and almost no level ground either and that make the extendable lower arms work best for me as they have vertical movement (a bit of horizontal too). I also have telescoping stabilizers too.

Negative, the lower mounts are not fixed, they are attached to the drop down bar that the scarifiers are mounted to so its impossible for the top link to have enough travel to bind the hooks.

No abuse, this was on a 32hp 6,000lb tractor, first use of the hooks. Had a box blade on, dropped the scarifiers. I believe the bar for the scarifiers contacted the tip of the hook and loaded that point and basically ripped it appart.
The lower 3pt links attach to the scarifier mount which is hinged.

Looking at the casting, I would say there is nothing weak or flawed with it, just loaded in a way it wasn't designed to be.

Not making comment on what happened with yours and I'm not an expert on casting metallurgy but from what I was told the other day, the quality of the metal and mixture used determines in large part the strength which is not something that can be seen by the naked eye. Swiss cheese effect on really bad castings is a good indicator but there are other factors apparently.

...Anyway, as far as ball sizes, it is as follows:

Cat 1 - 44 mm...
Cat 2 - 56 mm
Cat 3 - 64 mm
Cat 4 - 85 mm

Now I'm curious as to what category this one is, and for lower arms or top link? I bought a pair of these (by mistake as I soon discovered when I got back to the farm) but never got around to taking them back for exchange.
