Purpose

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. Any Specification published that is not in accordance with criteria of this Standard should be defined.

The static point trip force measurement shall be determined by Section 5 or Section 6 of this Standard, depending on the design of the shank assembly. When the test results are recorded, the test method used shall be identified.

The trip height measurement shall be determined by Section 7 or Section 8 of this Standard. When the test results are recorded, the test method used shall be identified.
