A method and apparatus for a saw device mountable on a self-propelled piece of equipment, such as tractor, is described. The present invention takes a limit curve provided by the user and combines that limit curve with a scale factor curve obtained from a model of the system to produce an allowable limit curve. The locking boss also has a top end with an inclined surface, which is disposed within the channel of the housing. The hoses and cables are bundled and wrapped in a static dissipative and abrasion resistant open mesh sheath or an overbraid to form the umbilical connection.
