Development of the John Deere 700 Series Engine

The 700 Series John Deere Engine was created to accomplish two basic objectives-increase Deere engine power available from the present 215 kW to a new maximum of 340 kW, and provide heavy duty engines for use in new larger Deere vehicles. An extensive program has developed an engine that meets stringent requirements for durability, performance, noise, and compact package size.

The 700 Series V-8 engine has a 140 mm bore, 127 mm stroke and 15.6 liter displacement. The engine has special design features which include unique solutions for the inherent difficulties of its “V” configuration.

This paper will emphasize the technical solutions to problems encountered and illustrate practical application of analytical skills available to a Deere engine designer. Sections on selected major engine parts will be included to project an image of the engine and to Illustrate design features and specific solutions.
