Homemade quick attach

[Baby Grand]

<snip>

Getting your finished product to the intended dimensions and alignment is a pretty basic fabrication skill.

<snip>

It may be basic, but as you are learning, it aint necessarily easy. I think this one ability is what distinguishes a top notch fabricator from us mere mortals. When you watch them work, they often appear to be just sticking things together and it all works. But if you could see inside their heads you'd see all the cogs and cams spinning, all the what ifs and what if nots playing out.

As an apprentice welder in a fab shop it took me a while to recognize that I had a lot more to learn than I thought would be required for the "simple" work that I was doing. There was an "old hand" who would make suggestions whenever he walked by my station. I'd ask "Why would I want to do that?" and he'd stop and talk for 10 minutes, telling me all the reasons he "would do that". I learned a lot from that guy, and the shop steward didn't seem to mind me talking with him, which was unusual.

There's some of those guys on here and they are happy to share their years of experience, which I think is best part of TBN. So stick to your guns, and if it doesn't look right to you, then cut it apart, tack it back together and reweld it until it does. You're close to having the quick attach that you want, the way you want it.

I had planned on doing this untill i looked up pricing on all this stuff. At the time NO WAY in **** was I spending that much on an SSQA. Thats precisely why i made this thead and built my own pin on QA. In the meantime this product came out at a very awesome price point, at least in my eyes its well worth it and would have definatly went that direction rather than building one.

The very reason I ordered my Kubota with their QA. The Titan one (without the boxing) is about the same price as what I paid as part of my deal. But now I have bucket and forks that fit this, soon to have grapple. Perhaps I should switch before I build anything else......Personally I'd prefer the $179 for the non-boxed version, but either way it's WAY cheaper than anything previously available.

Nothing wrong with ending up with a paper weight if the QA doesn't turn out the way you wanted if the learning experience was the primary goal.

So you have Kubota's "Pin on quick attach" like we all are copying in this thread? If thats the case I could still take off mine and still convert over my buckets and all that if I wanted the SSQA setup. I may eventually do that depending on how the one I built works, etc etc. It works good now but in 5 years it may be worn out or broken, who the **** knows. Thats kind of the beauty of the pin on quick attach, almost everything is able to be brought back to the way it was before hand. The only thing I had to modify was my bucket curl back stops had to be removed, other than that its all right back to the way it was.

I built mine a little differently then everyone else. It doesn't push the bucket out like kubotas design but I do have to cut the ears off the bucket. Anyway I used square tubing and cut one side off so make the brackets. This keeps the welding from messing up the alignment of the bushings. Here is a link to my build.

Using the square tubing is doggone clever.

Yup, ordered it that way. I knew I wanted QA but the dealer wanted to add $800 for the SS style and only an extra $150 for one like we've been discussing. All things considered, $650 was far too much for the loader plate as the bucket should be the same price or cheaper. Now if I could come up with a way to make this pin on style into hydraulic activated, I'd be all set as that's the main reason for me to switch to the SS style.

This is exactly what mine looks like, someone else's pic from another thread:

In your photo, I can see how they get the bottom pins to line up properly. There are two little tabs that catch the bushing on the outside. Excellent!

Gotcha. Thats why I brought up the titan SSQA adaptor. I think i priced the adaptor, and three plates to like 600$ some dollars. For me, thats feasible and not a bad price at all for the amount of time I spent on building the pin on quick attach, and the time it took me to modify a set of forks to utilize this setup. Other setups I looked at before hand were 600$ plus just for the SSQA adaptor.. I'm not putting out a plug for titan, just throwing it out there for people to know because I jsut went through this same thing, it was a lot of work keeping the pins in alignment and just doing the "basic" fabrication of it.

That's awesome. I hadn't thought of doing it that way, only with lever/cam action to slide the pins.

Where did you find that?

I designed and built it and have a patent for it now. I have a working model on my B7800 and I must say I am getting really spoiled by not having to get off the seat to change from bucket to snow plow to forks, whichever the case may be. :dance1: I will be installing one also on the new to me B26 I got last fall. You still have to get off the tractor to hook up the hydraulic lines for a grapple though.

Can you post a little more context as to how it works? From the video, I can see it going back and forth, but I can't really make out what's happening.

it was a lot of work keeping the pins in alignment and just doing the "basic" fabrication of it.

When I built my forks I did as much of the welding as I could leaving the lower bushings to last then tacked them in place with it mounted on the tractor. Had to grind out one of the welds on one bushing also as I took the pin out too soon and it warped. Once re-aligned I fully welded it with the pin in. But I was working on the bucket part not the QA itself so I may have been lucky that way.

From what I see, there's a hyd cyl mounted vertical acting on the sliver linkage which in turn operates the gold cam via the bolt/spring to latch onto the lower pin. Brilliant, as long as it doesn't push the bucket too far forward.

So the bucket has four permanently-mounted pins. The tractor picks up the top pins in a U-shaped cradle and the hydraulic/cam mechanism grabs the bottom pins?

3.75"-4" on average

That is correct.

Maybe you can help set me straight. For me, the use of a pin-based QA is just a money-saving thing. The pin-based QA is cheaper than an SSQA adapter, and I don't have to modify my bucket to use it. It seems to me like the hydraulic mechanism you've got would offset a lot of the cost difference between a pin-based and an SSQA system. At which point why not just go with SSQA?

I don't mean to be rude, and I hope I'm not. I'm just trying to understand the application of your system. Is it for people who already have a lot of pin-on implements, maybe? Or was it just a cool side-project that you did and then patented? Or do you expect it to have commercial application?

You are not being rude but I don't think this is the place to exercise a Bully Pulpit. Out of respect for the owners of the website I would be happy to go into detail if you would PM me. Thanx!

Nothing wrong with that. My Kubota one is 3.75"


I'd consider Magicheater's QA.
For me to convert to SS style, look at it this way: I have bucket & forks = 2 attaching plates @ $125 each ($230 each on EA) = $250 plus the work of installing them. A ready to go SSQA is minimum $600 (WR Long one on EA site is $837). So if I exclude the option of the Titan plates that just came available, it would cost me in excess of $1200 to convert to SS and still not have hydraulic (he has a manual one also). So if I could pick up his for a price point in that range (I don't know what the price is yet) and not have to do anything other than hook it up, it all works out equal for me.

I certainly see a market for it.

I found this tip on another TBN thread, and it would have been really helpful to me during my build, so I thought I would dump it here: for aligning bushings like on a QA adapter, weld in the length of DOM tubing whole, then when welding on the part is complete, cut out the center, leaving behind the desired length of bushing. This basically guarantees that the bushings will align. Awesome.
