Gravely also released an economy version of tractor in 1970, featuring a belt-driven 4-speed transmission and eight-horsepower (Kohler) engine, known as the 408. The engine was mounted at the front. This did not sell nearly as well as the popular all-gear units and was discontinued in 1977, when it was replaced with a heavy-duty professional ...
The R also incorporated live hydraulics. PowrTrol, as it was known, provided the operator the ability to lift equipment by the pull of a lever. A pump powered by the PTO clutch provided 1,800 psi (12 MPa) of hydraulic pressure to a lever controlled valve. At 45 hp (34 kW) at the drawbar and 50 hp (37 kW) at the belt, it was the most fuel ...
Larger than the 8N, the Golden Jubilee featured live hydraulics, a 50th-year Golden Jubilee badging, an overhead-valve "Red Tiger" four-cylinder engine and streamlined styling, but just as significantly, it was the first tractor Ford built after losing its court battle with Harry Ferguson in 1952 over the patents the Irish inventor held on the ...

Hydrostatic transmission, using hydraulic motors to convert the fluid energy into rotary propulsion; Hydraulic drive system § Hydraulic cylinder, using hydraulic rams acting on a swashplate or crank to convert the fluid pressure into rotation; Hydrokinetic transmission, involving one or more torque converters; commonly used in railway locomotives
The Ford N-series tractors were a line of farm tractors produced by the Ford Motor Company between 1939 and 1952, spanning the 9N, 2N, and 8N models. [1]The 9N was the first American-made production-model tractor to incorporate Harry Ferguson's three-point hitch system, a design still used on most modern tractors today.
Hydraulic power pack; Transmission lines Hydraulic hoses; Passive components Hydraulic cylinders; For the hydraulic fluid to do work, it must flow to the actuator and/or motors, then return to a reservoir. The fluid is then filtered and re-pumped. The path taken by hydraulic fluid is called a hydraulic circuit of which there are several types.
