Claim 24:
25. A method, comprising steps of:
introducing a lower planting arm vertically below a set of upper planting arms of a row unit;
aligning at least one opening defined in the lower planting arm with at least one aperture defined in a mounting plate of the row unit;
aligning at least another opening defined in the lower planting arm with at least one through-hole defined in a head frame of the row unit;
pivotally engaging the lower planting arm and the mounting plate with one another, via at least one attachment assembly, via the at least one opening and the at least one aperture;
pivotally engaging the lower planting arm and the head frame with one another, via at least another attachment assembly, at the at least another opening and the at least one through-hole;
selectively engaging an actuating device with the lower planting arm via one of a first mount of a first bracket of the lower planting arm and a second mount of a second bracket of the lower planting arm; wherein the first bracket and the second bracket operably engages with the at least one linkage arm;
engaging a first end of the first bracket with a first linkage arm of the lower planting arm at a first position;
engaging a second end of the first bracket with a second linkage arm of the lower planting arm at a second position;
engaging a first end of the second bracket with the first linkage arm of the lower planting arm at a third position; and
engaging a second end of the second bracket with the second linkage arm of the lower planting arm at a fourth position;
engaging at least one outer bushing with a first material inside of the at least one opening of the lower planting arm;
engaging at least one washer of the at least one attachment assembly having a second material with at least one connector of the at least one attachment assembly;
engaging at least one inner bushing of the at least one attachment assembly having a third material with the at least one connector; and
engaging the at least one inner bushing with the at least one outer bushing;
wherein the first material is harder than the second material and the third material;
wherein the first bracket, the second bracket, the first linkage arm, and the second linkage arm collectively define a single, monolithic member.
