There is a fellow that builds accessories for kubotas, tool holders, steps and a variety of other things. Not sure what the website is, but has some great ideas that he puts up on youtube
Lots of good info on orangetractortalks. Com too
I should go find his channel,here it is https://youtube.com/@7863348
Theres lots to sift through, but any handy guy can use his ideas. @Sublime one could find some ideas there too.
