ENGINE DETAIL
The Muir-Hill 171 features a robust Perkins V8.540 diesel engine with 539 ci displacement, delivering 177 hp and 410 lb-ft of torque, making it suitable for heavy-duty agricultural applications. Its 16.5:1 compression ratio and direct injection fuel system enhance efficiency and power output, while the torque peak at 1600 RPM provides excellent low-end performance for demanding tasks. One challenge could be the 24V electric starter; ensure proper battery maintenance to prevent starting issues in cold weather scenarios.
