A dielectric ceramic that can be sintered at a sufficiently low temperature and has a desired specific resistance at a high temperature, and a multilayer ceramic electronic component using the dielectric ceramic are provided. The system is comprised of a sealed battery pack enclosure configured to hold a plurality of batteries, where the battery pack enclosure is divided into a plurality of sealed battery pack compartments. One or more shear assemblies are affixed to the frame in a spaced relationship along a length of the frame, wherein each of the one or more shear assemblies includes a shearing blade disposed at a distal end of the shear assembly and configured to operate below the surface of the soil to sever the roots of planted vegetation as the plow is pulled through a field.
