Sicma RD 185 Rotary Tiller — 73" | 35–65 HP | 4-Speed | 8" Tillage Depth | Cat. 1/2

The Sicma RD 185 is a fixed, medium-heavy duty 4-speed rotary tiller with a 73″ working width and up to 8″ tillage depth, built for tractors from 35–65 HP and engineered for demanding, high-output tillage operations. A SICMA-built 4-speed gearbox with tapered roller bearings, side gear drive in oil bath, boxed frame, and “long life” sealed rotor bearings deliver four selectable rotor speeds — from 180 to 259 RPM — to match soil conditions and optimize performance. Adjustable side skids for depth control, a lower 3-point hitch with adjustable width, a Universal shaft size 6 with flexible clutch, and a parking stand round out a tiller built for producers who need serious ground-engaging capability.
