This left-side chisel is the replaceable ground-engaging tip for a reversible plow body. It mounts to the plow leg and fractures and turns the soil ahead of the moldboard. The chisel carries the primary wear load during operation; a worn tip reduces penetration depth and increases draft force, causing uneven furrow depth and higher fuel consumption. This part is machined to match the mounting pattern of the original assembly so that the bolt holes align without modification. When installing, use the specified bolt grade and torque to the manufacturer's value.
