The Digit company made a couple of different sizes, including there 12" they had an 18",24", and a 36" grave digging bucket. i cant seem to find any of them on the internet though. I plan on making one thats capable of holding about 2 cubic feet of dirt. i have looked at other small excavators and they all seem to have a different configeration on top of the bucket for there pins. alot of these buckets take a larger pin than what my digit takes, I have contemplated making bushings to slip over the pins i currently use so that my machine could accommadate a larger different brand bucket.
