I finally got all the parts to convert my D120 pin-on bucket to an H120 quick attach bucket system. The reason for this was I want the Artillian fork setup and after speaking to Chris and finding out the pin-on system does not work with his forks.......well that did it! I HAVE to own his forks! Parts can be obtained through John Deere for around $340. First step was to remove the 4 bolts or "pins" that hold the D120 bucket on. Once this was done, the brackets that are welded to the bucket must come off. I used a 4 1/2" electric grinder to quickly remove all the factory welds and the brackets were off. I them bolted on the quick attach brackets to the loader frame. This was pretty straightforward with the long pin going through the lower holes of the brackets. The existing upper D120 pins are a perfect fit into the new H120 brackets. I then positioned the bucket up against the brackets to make sure the bucket will be oriented properly to the loader brackets. I made sure that up/down height was also correct. I didn't want the bucket to have a higher or lower full raise height that stock. I then painted all cleaned metal surfaces with weld-through primer. This stuff is necessary whenever welding must be done to bare metal where parts of the welds can never be painted due to access. The paint is a silver color in the photo. After tack welding the upper hook brackets in place, I removed the bucket and did a complete weld job to both brackets. After the upper brackets were welded it was time to move on the lower lower quick attach pins. I reinstalled the bucket on the loader frame and raised the whole thing up enough so I could mark where the pins would go. I had to cut about 1/4" off the new pins because they stuck out too much and I did not want the bucket to flop around with the lynch pins installed. Once pin position was marked I fully welded them to the bucket. Note here that although you can't see it I ground the pin surface to be welded at a deep 45 degree angle so the finish weld was flush with the pins. This is necessary because if any weld protrudes outside of the pin diameter the bucket will not sit flat against the brackets. After everything was welded and proper fit was correct I painted everthing and reinstalled the bucket. And there you have it, a quick attach bucket for the D120 loader.

Wow, what a great job! That really shows why one should purchase the H120 up front!:good2:

Oh, this "weld through primer" sounds interesting as well-gonna have to research that a bit.

Thanks Kenny, I thought I would save money going with the D120 but....... As far as weld-through primer goes, it's a MUST! Just think when you clean 2 pieces of metal for welding and then weld them together. The welds may not completely seal the bare metal surfaces and then you have corrosion from the inside out. Our bodyshop uses it on everything, it is a staple to any well done welding job. The reason it is weldable is the paint contains iron particles which conduct electricty. I use the 3M version which is readily available at any good parts store.

Nice job indeed. Thanks for the info on that weld-through primer. Wish I had known about that before. Gotta get some.

is the D120 bucket that much smaller? my 200cx(predecessor to the H120) has the hooks slightly below the upper surface of the bucket.
Great job BUT you need to support the top hooks better on the bucket. as they are, they are either going to bend or tear away from the bucket and possibly break the lower pins.
they need some support added above the upper surface of the bucket.

Nice job. I have a project for my 3720 with the CX loader that I need the hooks and pins. I am struggling to find them on the jdparts website. Do you have those part numbers for the hooks and pins? Thanks

Hello scrappy, I agree with you, I think I may need to add gussets to the top of the brackets to support them. They don't appear to stress in any way now but I'm afraid over time they may. I will keep a close eye on them and add support if needed. The bucket is a little smaller and that is why the brackets are a little higher. Also, the brackets I used are not the exact ones on the H120 bucket. They are just universal JDQA brackets.

Hooks I used to build my grapple W43359, Pins: W47211 Two of each run about $70- Hope that helps! I used mine on a 4200 w/loader. ~Scotty

Scotty, I think those are different numbers than what I got. I'm sure yours would work fine. My numbers started with a "BW". I'll find out tonight

We have also discussed recently about making your own with CAT2 pins and angle iron.

Yeah, I was going to make them myself but because I was unfamiliar with what they look like (my dealer is 54 miles away) I decided to just purchase JD brackets the first time around. Now that I know I will make my own next time.:unknown:

P/N W47211 is $20 each. I'm thinking a CAT2 pin cut to fit is more cost effective. I think someone mentioned it here. I will order the hooks. I am making a quick attach for a BOTA for a friend.

Just to mention, Gents, those pins from Deere are what are known as a medium carbon steel which is supposed to be preheated and stress relieved upon welding to prevent cracking. I don't understand why Deere would be using such a material. It's definitely not necessary for what those pins do.

Here is an old photo from the early days of some Deere pins being preheated before welding into the fork frames. I remember thinking they looked like a regiment of Weebles in there, ha ha. Other than that, I don't miss those things at all. (The Deere pins were abandoned for a custom made version designed specifically for the fork frames)
