I have an old style new holland quick attach, I purchased this adapter, hoping it would work, it took a slight modification to make it work, but it fits and works perfectly now. Plus it was a lot cheaper than the $1800.00 version. The unit is built very well, and im sure i will get years of use from it, thus extending the usefulness of my old john deere loader. I'm now able to use all the newer buckets and attachments.
