ASAE/ASABE S591.1 (R2022)

The purpose of this Standard is to establish a uniform method of measuring the static point trip force and trip height of agricultural tillage shank assemblies (see Figure 1). This includes field cultivator or conditioner shanks, chisel plow shanks, and subsoiler (or ripper) shanks. It is limited to those shank assemblies utilizing a spring cushion, or “S” tine/coil shank design. Rigid, non-flexing shank assemblies are excluded.
