Summary:The subject matter of the present invention relates to a plow guide for a chain-pulled plow for use in underground mining operations, with plow guide troughs 20 and 50 having multiple parts and being connectable to one another by means of coupling elements so as to be tension-proof and angularly movable. Each plow guide trough has a center piece 21 and 51 with superposed chain guide channels 10 C, 10 B, 10 D, to both sides of which center piece an end piece, 22,23 and 52,53 is joined by welding, which end piece is a single-piece casting with superposed chain channel sections that are separated by a sliding spacer piece that is cast on. To make available a high-performance Gleithobel system with a high tool life, cast-on holding pockets 24,25 and 54, 55 -which are open on the working face side-for toggle connections with toggles 1 as coupling organs are disposed on end pieces 22,23 and 52, 53 .
