Its compact size allows for maneuverability in tight spaces, while the powerful hydraulic system enables it to handle a variety of attachments, such as buckets, forks, and augers.
Common Issues and Maintenance
Despite its robust design, the Bobcat 773 may experience certain issues over time:

1. Hydraulic System Problems: Users have reported instances where the hydraulic system would intermittently fail, particularly affecting the boom and bucket functions. This issue often resolves itself after restarting the machine, suggesting potential electrical or sensor-related problems.
   
2. Fuel System Failures: The fuel pump may fail, leading to engine stalling or rough operation. Regular maintenance and timely replacement of the fuel pump can mitigate this issue.
   
3. Hydraulic Hose Failures: Over time, hydraulic hoses can deteriorate, leading to leaks or bursts. Regular inspection and replacement of worn hoses are essential to maintain system integrity.
   
4. Parking Brake Issues: The parking brake mechanism, which uses a spring-loaded cable assembly and ratchet system, may wear out over time, leading to failure. Regular maintenance and timely replacement of components can prevent this issue.
