Abstract
Abstract This log splitting device is designed to be attached to a backhoe vehicle, in place of its digging bucket, which will enable the vehicle to be driven through the woods, brush or mud to split logs by the hydraulic components existing on the vehicle. Primarily, it consists of a base plate or platform, having an "I"-beam attached. The "I"-beam includes brackets for securing it to the beam of the vehicle, and a wedge member is slideable on the beam by an attached channel, so as to split a log on the base plate, and the hydraulic cylinder of the boom structure is used to apply hydraulic force to the wedge member, to split the log.
