Hydraulic System for New John Deere 60 Series 4WD AG Tractor

A new hydraulic system was developed for a four wheel drive (4WD) agricultural tractor to coincide with the new modular design of the vehicle. Challenges such as lubrication and cooling of separated drivetrain components, adaptation to stand alone transmission modules, decreased maintenance time, and design of an optional electrohydraulic controlled 3-point hitch for implement lift were addressed. System considerations and design approaches are outlined.
