John Deere 4640 Specifications & Technical Data on this page.
The 40 Series tractors from John Deere were presented in 1977 and introduced to Europe late 1979. The objective of the series was to provide a tractor with large engine size for heavy lifting, and this is amply met. This model includes engines that range up 7 litres, which has 177 horsepower at 1400 rpm – these are some powerful motors! Standard transmission included 16 gears + 2 speeds or full powershift technology; optional upgrades include fuel injection technology as well as cab options.
