I recently acquired a dearborn 10-56 2 bottom plow. The plow will mainly be used for gardening purposes, but i do have some terraces to build up so it may see quite a bit of work. It has seen some wear, but still does a good job. Was just wondering where a good place was to look for parts. Coulters are worn, tail whel seems to need attention, shears could used replaced, leaading moldboard is not far from being worn through, frogs may as well be replaced to. Just curious as to where the best/cheapest place to get parts would be, possibly I should start out by trying to find a parts manual for the plow. Any help or input is appreciated.
