History and service record of FD45P-1

A Furukawa dozer. Owners in a 2013 Heavy Equipment Forums thread and a 2018 Yesterday's Tractors thread discuss the FD45 as a Furukawa machine and say the Hitachi DX45 dozer looks just like it, with parts and manuals hard to find for either.

Furukawa's background. Furukawa's company history begins with the Kusakura Copper Mine in Niigata in 1875, records a machinery works at the Ashio Copper Mine in 1900, and lists the first rock drill made in Japan in 1914. History, Furukawa Co., Ltd..
