# Integrated group of excavator control assemblies

## Abstract

A system for controlling a track propelled excavator that has an allowable 360 degree swing arc including: (a), a positioning controller for all five (propel, swing, boom, arm,and bucket) motions: (b), positioning of small members that represent the large deck, boom, arm, and bracket by a flow of fluid in series with each large member&#39;s actuator--eliminating a need for transmitting each digging member&#39;s angular position back to the controller; (c), a handle with tooth type edge that represents the large bucket, for scraping along templates for guiding desired earth contours; (d), guide plates and positioning switches for acheiving accurate and safe placement of the bucket during swing and digging motions; (e), a mobile armrest that allows ease of operator&#39;s small scale motions when guiding large scale digging: (f), and, an assembly for pulling the small bucket/handle through a series of desired small scale positions to achieve automatic trench digging.
