Rotary Plow

 

(rotary tiller), a mounted implement for loosening and inverting the soil. There are rotary plows for complete soil cultivation, plows for interrow tillage, and special types. In the USSR rotary bog, forest, and field plows (FBN-0.9, FBN-1.5, and FBN-2.0) are used for complete soil cultivation to dress the soil after the primary plowing of drained bogs, to prepare the soil for planting forest crops, and to improve pastures and meadows; they are also used in hotbeds and hothouses. Rotary orchard and row plows (FP-2, FS-0.9, and FS-0.7) are used for interrow tillage. Special machines include rotary trench plows (KFN-1200, ETR-171, and other models) and rotary trench clearers (EM-202 and D-490M).

The working member of a rotary plow consists of a rotating drum with straight or curved blades or tines fixed uniformly along the perimeter of disks. The drum is driven by a takeoff shaft from the tractor engine. The drum has a diameter of 300–800 mm; there are from four to eight blades on each disk, and the drum rotates at a speed of 160–320 rpm. The operating width is 0.7–4.2 m, and the depth of tillage is 6–20 cm. The machines have a productivity of 0.3–2.0 hectares per hour. Rotary plows are used extensively in foreign countries. They have operating widths of 1.3–2.2 m and cultivate to depths of 25 cm.
