Machine Overview
The Bobcat 773 C-Series, produced primarily in the mid-1990s, is a compact and powerful skid steer loader designed for diverse construction, landscaping, agricultural, and material handling applications. With a balance of strength, maneuverability, and operator comfort, the 773 C-Series remains a reliable workhorse in the skid steer segment.
Key Specifications
The Bobcat 773 C-Series offers dependable power and controls tailored for mid-1990s skid steer operations, featuring optional BICS safety interlocks that may differ in design from later models. In cases of BICS lockout alarms, especially on early analog gauge units with foot controls, locating the lockout solenoid may require hands-on inspection or professional guidance, as manuals might not cover all model variances. Understanding the BICS system functionality and hydraulic control architecture assists in troubleshooting and maintaining safe, efficient loader operation.

Key Specifications
- Engine: Liquid-cooled diesel engine delivering approximately 46 horsepower.
- Operating Capacity: Rated operating capacity of 1,700 pounds (approximately 771 kilograms) under SAE standards.
- Tipping Load: Approximate tipping load is 3,800 pounds (1,724 kilograms).
- Operating Weight: Machine weight around 5,457 pounds (2,475 kilograms).
- Hydraulics: Auxiliary high-flow hydraulic option delivering about 15 gallons per minute, allowing use of high-demand attachments.
- Dimensions: Approximately 130 inches in length and 68.1 inches in width, with a height near 76.3 inches.
- Travel Speed: Typical maximum speed is not specified but aligned with similar models offering efficient jobsite mobility.
- Controls: Typically features foot pedal controls for lift and tilt arms and dual hand levers for travel and steering, with BICS (Bobcat Interlock Control System) as an optional safety feature.
- The BICS system is designed to prevent unintended machine motions, locking out boom lift and tilt functions under certain unsafe conditions.
- In some models, BICS monitors control valve solenoids and other hydraulic components, indicating faults via blinking lights with diagnostic codes.
- A blinking control valve light with three flashes typically indicates a problem with the BICS control valve solenoid; however, variations exist depending on model year and gauge types (analog versus digital).
- Early 773 C-Series models with analog gauges may not feature removable control valve assemblies or individual solenoids, differing from later models with modular designs.
- Unlike later digital gauge models, the 773 C-Series with serial number around 509639321 and foot-controlled hydraulics may have the BICS lockout solenoid located elsewhere, possibly integrated within the control valve housing or mounted remotely in the hydraulic circuit.
- Service manuals for later models may not provide detailed location information for the solenoid on earlier units, requiring physical inspection or consultation with seasoned Bobcat technicians.
- Typical steps to find the solenoid include tracing hydraulic lines from the control valve assembly, checking electrical wiring harnesses for solenoid connectors, or inspecting near the hydraulic valve bank.
- When encountering BICS lockouts indicated by flashing lights with no removable valve assembly apparent, reviewing wiring connections and solenoid integrity is essential.
- Verify all safety interlocks and switches, as faulty switches can cause false lockouts.
- Consulting Bobcat dealer repair centers or experienced mechanics can clarify model-specific configurations.
- BICS (Bobcat Interlock Control System): A safety system preventing accidental hydraulic or travel movements if unsafe conditions are detected.
- Control Valve: Hydraulic valve managing fluid flow to cylinders for lifting, tilting, and other functions.
- Solenoid: An electrically controlled valve actuator enabling or disabling hydraulic flow.
- Foot Controls: Operator input method where pedals control loader arms and bucket functions.
- Hydraulic Circuit: Network of valves, lines, and actuators channeling hydraulic power.
