I guess your J2030 did not come with the QA loader. LS lists it as optional for that model.
You can order what you need from your dealer or add your own QA assy. Adding your own QA would take some fabrication work. If you are not into fab work then just order from your nearest dealer.
What about my bucket? Won't there be fab work to that? I'm not scared of a little fab work. I'm thinking from the dealer it will be expensive. Any other options?
Yes, There are several aftermarket companies that sell QA plates for both the tractor loader arm side and the mating side for the bucket. Once you get the loader side QA installed then the skidsteer attachments will work.
Here's a few sites. Most are universal but check the sites for New Holland QA which will be the closest match.
