The elderly farmhouse had a lower probability of employment in most agricultural forms compared to a non-elderly farmhouse but it was analyzed that the effect will be large on special crops and mushrooms in the case for short term employments, and inn middle to long-term employments the effect was large for animal husbandry. The possession of agricultural machine can be thought to be related in the replacement relationship of manpower employment but it was analyzed that in most of agricultural forms, it was only related with high employment probability, and if it is related to manpower that can operate the agricultural machine, it can be analyzed that it is possibly a mutually complementary relationship (+).
