This is the Ford 6600 parts catalog, an illustrated breakdown of the four-cylinder agricultural tractor built from 1975 to 1981. Across 724 pages it lays out exploded figure diagrams with part numbers for nearly every assembly on the machine, often listed under the New Holland name as well.
Sections span wheels and weights, brakes and handbrake, front axle and steering, rear axle and center housing, the hydraulic system and linkage, engine, transmission and PTO, cooling, fuel and air systems, electrical and lighting, plus cab, seats, decals, and accessories.
To find a part, use the figure-number index at the front and Adobe search to jump straight to the right diagram. It is the reference to keep beside you when ordering correct components for a repair, restoration, or routine service on your 6600.
