Zusammenfassung:A row unit for a seeding machine includes a frame supporting a gauge wheel and a seed meter. A depth stop assembly includes a stop setting an upward travel limit of the gauge wheel with respect to the frame, and a handle that is lockable and releasable to move the stop to select among seeding depths. A downforce actuator is operable to generate downforce to be applied through a gauge wheel arm and the gauge wheel to the soil. A downforce sensor is incorporated into the depth stop assembly and movable therewith. The depth stop assembly includes a multi-piece body having a first piece receiving the handle, and a second piece defining a pivot. The first piece of the multi-piece body includes a handle-receiving receptacle portion, a fastening portion for fastening to the second body piece adjacent the pivot, and a portion therebetween forming a housing of the downforce sensor.
