I have experienced the same as far as the JD-Hitachi parts, Hitachi is always cheaper even if it's not in stock. Just to clear some things up though, John Deere makes the following of their products---All skidsteer models, not the older ones, New Holland made them,---- the bulldozer line from models 450-550 series, the 650-1250 are built by Liebherr and painted in yeller bellied yellow, I got into a good argument with a JD sales rep over this and I proved him wrong when I showed him a printed out PDF of Liebherr's same machines,---- the TLB (tractor loader backhoe) line from the smallest little compact 110 TLB to the biggest 710 series, no questions there, tractors are what they are good at, anything painted green is questionable, some farm tractors are made in pieces in countries like Mexico and France and shipped to North America so it's a grey area,---- all the Excavators are made by Hitachi, Deere owns over 50% of the Hitachi name,--- all graders are made by Champion from the smallest to biggest and the Articulated Dump Trucks (ADT) are made by Moxy and painted yeller.
