ABSTRACT:
A trip mechanism 41 for a plow standard 11 includes a pair of toggle links 46, 61 having their remote ends pivotally connected, respectively, to a plow frame 15 and the standard 11. Link 61 includes a leaf spring 63 with a rolled end 86 pivotally connected to the link 46 by a pin 88 normally disposed in an overcenter position; however, when excessive working forces are encountered, the leaf spring 63 deflects somewhat in the manner of a cantilevered beam causing the pin 88 to move from its overcenter position to a tripped position thus allowing the plow standard 11 to swing upwardly about its pivot axis 16.
