Kioti backhoe subframe and mounts

[Amvcane]

I have a KB2475 hoe on a CK35. The manual only showers a DK and a DS subframe. The DS diagram looks like what came with my tractor. Cannot get pics right now.

Interesting. I have never seen the factory manual on the 2475. Your 1st photo shows the toplink
mount on the hoe. Do later pages tell you to use the toplink, or not?

Using the toplink connection or not, was/is an issue, but I think it should be used, based on
photos and a video of fatigue damage on well-used units. This is an old-fashioned design; I
much prefer a "4-point" style of subframe, even if you have to go custom.

On CK20s and the new CK35 replacement (CK3510), the fuel tank is behind the driver's seat.
This caused some minor changes to the newer 2475 subframe, making it stick out back even more.
On my property, I would not be able to even drive across places where I have swales.

This is great - thank you! Can you tell me how part #3 (the rear bracket) mounts to the hitch? I can't see how that attaches at all.

I'm not a expert on these but as for your comment re: top link: if you're talking about part #4 from the second image, I believe that's just a cross bar from the subframe to the hoe; not a top link. There is one on each side.

The manual does not tell you to hook up a top link. Actually the seat support and center platform is in the way. They are both removable, I'm guessing that whoever makes the hoe also makes a 3 pt hoe and this is a shared part.




Here are some pics of the rear mount 2012 CK35. Different from the parts diagram of the DS35, the rear mount has two legs and an arch going over the pto.

Wouldn't a 3-point hoe also need the seat?

The earlier 2375 also has the toplink hole, and factory folks said to use it. Dealers sometimes
said not to use it.

You get a lot of flex if you don't use it. Hence the damage on hoe frames with lots of hours.

Next time I mount the hoe I'll see if I can hook up the top link. It definitely will help stop the hoe from rolling back when putting down force on the bucket.
The top link would be in compression and putting all the force to the mount on the back of the transmission case. Not sure if it was designed to take a large compressive force on the top link.

Yeah this is definitely different than what the diagram shows. Are both versions bolted to the hitch or are they welded?

 

[Amvcane]

Not sure what you mean by hitch. The diagram and pics show 6 bolts at the bottom of the tractor and 2 bolts below the pto. The unit on my tractor shows this and also, 2 legs going above the pto secured with 4 bolts about the top link mount. Nothing is welded to the tractor.

Only with a 3-point setup would the toplink take all the forces (tension and compression) of the hoe
in use. In the factory Kioti subframe setup, the forces on the toplink are only the forces that
flex the subframe, since the hoe is not free to rotate as it is in a 3-point setup.

I have never seen this hoe or the 2375 in a 3-point setup, and I do not know where or if it was ever sold
for 3-point mounting. It seems strange that Kioti would provide a toplink mounting point
that would not be used.

With hoes on CUTs, a flexing subframe is not good.
