Introduction
J.I. Case 730 Standard-Tread Tractor
The J.I. Case 730 is a standard-tread agricultural tractor produced between 1960 and 1969 in Racine, Wisconsin. As part of the 700 series, this model was designed as a versatile, mid-range workhorse for general field operations.
Engine and Performance
The tractor is powered by a 4-cylinder, liquid-cooled diesel engine with a displacement of 267 cubic inches (4.4 liters). It features a 15.2:1 compression ratio and generates 62 horsepower. The engine is designed for consistent performance, utilizing a 1-3-4-2 firing order and requiring a 30-quart coolant capacity.
Transmission and Drivetrain
Operators have access to two transmission configurations: the Case-o-matic system, which utilizes a torque converter, or a traditional mechanical dry-disc clutch with an unsynchronized gearbox. Both options provide 8 forward and 2 reverse gears. The machine is configured as a two-wheel-drive unit with manual steering, though power steering was available as an optional upgrade.
Hydraulics and PTO
The hydraulic system is an open-center design capable of delivering a pump flow of 15.5 gallons per minute (58.7 liters per minute) with a 17-gallon reservoir capacity. It supports four valves for implement control. The rear independent PTO offers both 540 and 1000 RPM settings, providing flexibility for various PTO-driven implements.
Dimensions and Hitch
The Case 730 features a Category II Case Eagle Hitch with a rated lift capacity of 1,350 pounds (612 kg). With a wheelbase of 102 inches (259 cm) and a total weight of 7,000 pounds (3,175 kg), the tractor is built for stability. It sits on 6.00-16 front and 14.9-30 rear agricultural tires.
Conclusion
The Case 730 remains a representative example of mid-century American agricultural engineering. Its combination of a 62-horsepower diesel engine, dual-speed PTO, and hydraulic versatility makes it a capable tractor for standard traction and implement-based field work.
