The list of JD firsts would take several pages, especially if you factor in things they developed but never marketed. They had a powershiftable two-speed unit designed to go inside a two-cylinder belt-pulley in the 20s - decades before IH introduced the Torque-Amplifier, but it never saw production past the prototype stage. They had the first mechanical power-lift on the "GP". The first HYDRAULIC power-lift on the "A" in '34 - otherwise known as the Power-Lift. The first hydraulic system capable of operating a double-acting remote cylinder and the rockshaft - otherwise known as the Power-Trol. The first multi-barrel carburetion - the duplex carbs found on the first numbered two-bangers. The first (and only) rack-and-pinion wheel tread adjustment on the same tractors. First factory-engineered power-steering, not an add-on unit from and outside source. First closed-center hydraulic system on the New Gens. First power-assisted wet-disk brakes on the New Gens. First inboard-planetary final-drives - once again on the New Gens. Starting to wonder if you might get a little more than you bargained for on this question???
