I have looked all over for a post hole digger to fit on my BX2200. Here's photographic proof that they do exist. This is a Worksaver model 300 w/ 30" auger. A 12" extension is sitting on the bucket but I haven't tried that yet. I think the 30" auger will have to be in the ground before the extension will fit as there is only about 8-10" of ground clearance. I haven't tried drilling extra holes in the lift arms to get more height because my baby is still too new. Prices were $488 for the digger, $94 for the auger, and $79 for the extension. Hope this helps anyone looking for a digger.
