ABSTRACT:
A spring tooth chisel plow has its upper shank secured within a channel retainer pivotally mounted adjacent the rear edge of the retainer to a mounting bracket secured to a tool bar. The shank of the chisel plow is held within the channel retainer by a transverse clamping bar positioned radially from the main pivot, the forward end of the shank being fixed to the channel retainer. The upper surface of the retainer normally abuts a complementary surface on the mounting bracket, which supports an upwardly extending compression spring assembly. A tension bolt pivotally connects the forward end of the retainer to the upper end of the compression spring assembly, whereby force exerted on the chisel point of the plow is resisted by the compression spring assembly.
