Corn Planter

Corn Planter 

a machine that plants size-graded corn kernels while simultaneously applying granulated fertilizers.

In the USSR, the SKNK-6 and the SKNK-8 corn planters are used for square-nest planting, for which they are equipped with a checkrow wire. For single-grain planting they are used without the checkrow wire. The SKPN-8 planter is also used for sowing kernels singly. The working parts are driven by drive-support wheels and the checkrow wire. The SKNK-8 has been standardized with the SKNK-6. The SKPN-8 does not have nesting attachments. The productivity of the SKNK-6 is as high as 3.5 hectares per hour (ha per hr); of the SKNK-8, 2.2–2.9 ha per hr; and of the SKPN-8, to 4.5 ha per hr. The operating widths are 3.6–4.2 m, 4.8–6.3 m, and 5.4–6.3 m, respectively. The SKNK-6 plants six rows; the SKNK-8, eight; the SKPN-8, from four to eight. The width of the interrow spaces is 60, 70, or 90 cm with the SKNK-6; 60, 70, 90, or 105 cm with the SKNK-8; and 70, 90, 105, or 140 cm with the SKPN-8.
