ENGINE DETAIL
The Best Sixty tractor, featuring a 4-cylinder gasoline engine with a substantial displacement of 1128.2 ci (18.5 L), offers strong torque for heavy-duty applications. With a bore and stroke of 6.50 x 8.50 inches (165 x 216 mm) and a rated RPM of 650, it is optimized for low-end power, making it suitable for plowing and hauling tasks. However, its lower RPM may limit its top-speed capabilities, making it less ideal for tasks requiring higher velocities.
