Abstract
An electromagnetic bucket positioner having an electromagnet disposed to selectively latch, when energized, a directional control valve of a bucket positioning system. The electromagnet is arranged in such a manner that only when a manually operable control lever is shifted to a rack-back position, the electromagnet serves to latch the control lever in the rack-back position. A normally-closed electric switch is provided and is adapted to be opened upon selected movement of the piston rod of a hydraluic cylinder associated therewith, so as to interrupt electric current flow to the electromagnet, de-energize the same and release the control lever. A loose spring device is provided in the system to facilitate movement of the control lever from the rack-back position if and when desired.
