The story

The 4430 arrived on 19 August 1972 as part of John Deere's Generation II range, the 30 series that replaced the long-running 20 series. It took over from the 4320 and quickly became the best seller of the new line.

Power came from the turbocharged 404 cubic inch six-cylinder diesel, good for a little over 125 PTO horsepower. The big news was the Sound-Gard body, a cab designed with Henry Dreyfuss Associates that sat the driver in a quieter, sealed space and set the look of Deere tractors for two decades.

Buyers could choose Syncro-Range, Quad-Range, Power Shift or a creeper gearbox. Some owners felt the engine lacked pull at low revs and that the rockshaft lifted too little, points Deere addressed with the 4440 in 1977.

Did you knowThe Sound-Gard cab that made its name on the 4430 stayed in use on Deere tractors from 1973 until 1994.
