Machine Overview
The Case 680G is a midsize backhoe loader widely valued for its reliability, versatility, and solid performance in construction, agriculture, and utility work. It features an efficient 4-cylinder J.I. Case A336DDC diesel engine delivering 80 horsepower net (88 gross), providing sufficient power for a variety of digging and loading tasks. The engine displaces 5.5 liters (336 cubic inches) and is designed for durability and ease of maintenance with features like a dry air cleaner and direct fuel injection.
Hydraulics and Transmission
The hydraulic system is an open-center design with a 13.8-gallon (52.2 liters) reservoir supporting a pump flow of 27.2 gallons per minute (103 liters per minute). This system powers both the loader and backhoe, allowing smooth operation of implements with precise control. The 680G uses a 4-speed power shuttle transmission that facilitates quick directional changes without clutching, enhancing operator efficiency.
Backhoe and Loader Performance
The cab is available as an option and offers an ergonomically designed space with optional features to reduce fatigue during long work shifts. Electrical components include a 12-volt system with a 40-amp alternator supplying power to the starter and accessories.
Maintenance and Reliability
With a fuel capacity of approximately 30 gallons (113.6 liters) and an engine oil capacity of 11 quarts (10.4 liters), the 680G offers reasonable operation time between refuels and oil changes. The engine’s torque is rated at 233 lb-ft (316 Nm) at 1500 RPM, providing strong low-end power crucial for heavy digging and loading efforts.
Routine maintenance, including regular oil changes, hydraulic fluid checks, and filter replacements, is essential to maximize the machine’s lifespan and maintain performance.
Glossary
The Case 680G’s blend of power, responsive hydraulics, and operator-friendly transmission makes it a reliable choice for medium-sized earthmoving and material handling jobs. Operators benefit from smooth shuttle shifting and ample breakout force, reducing cycle times and fatigue on demanding workdays.
Industry Perspective
The 680G continues to be favored in used equipment markets due to its straightforward mechanical setup and reliable engine, with strong support for parts availability. Contractors note its adaptability to various attachments enhances jobsite productivity.
Conclusion
The Case 680G backhoe loader stands as a balanced machine integrating efficiency, power, and operator comfort, suitable for a versatile range of construction and agricultural operations.
