Two Legendary Two-Cylinder Diesels — One Complete Factory Repair Reference

This manual covers both iconic John Deere two-cylinder diesel tractors in a single factory document:

John Deere 720 Diesel — introduced as part of the 20-Series lineup, the 720 Diesel brought the two-cylinder diesel engine to the high-horsepower end of the John Deere row-crop tractor range. The 720 Diesel is powered by the John Deere 360.5 cubic inch two-cylinder diesel engine — one of the largest displacement two-cylinder tractor engines ever produced — delivering the power and torque that made the 720 Diesel one of the most capable row-crop tractors of its era. The 720 Diesel features the unique John Deere starting system using a small V-4 starting gasoline engine — the pony motor — to start the large two-cylinder diesel, and the hand clutch starting procedure that is one of the defining operational characteristics of the late two-cylinder John Deere diesel tractors.

John Deere 730 Diesel — the 730 Diesel is the 30-Series successor to the 720 Diesel and represents the absolute peak of John Deere two-cylinder diesel engineering. Sharing the same fundamental two-cylinder diesel engine architecture as the 720 Diesel with refinements developed through the 720 production run, the 730 Diesel was the most powerful standard-production two-cylinder diesel tractor John Deere ever built. The 730 Diesel retains the pony motor starting system, the same fundamental Powr-Trol hydraulic system, and the same core transmission and drivetrain architecture — with updates to the operator station, instrumentation, and selected mechanical components that distinguish the 30-Series from the 20-Series. The 730 Diesel remains one of the most sought-after two-cylinder John Deere tractors among collectors, restorers, and working vintage tractor owners worldwide.
