ENGINE DETAIL
The AGCO Allis 8785 features a robust Sisu 6-cylinder turbocharged diesel engine with a displacement of 6.6 L, providing substantial power for heavy-duty tasks. Its high compression ratio of 16.5:1 enhances fuel efficiency but may necessitate careful operation with lower-quality fuels to prevent knocking. At a rated RPM of 2200, this tractor is well-suited for agricultural applications, although its performance may be limited by the dual dry element air cleaner's need for periodic maintenance in dusty environments.
