Rotary Ridger
The revolutionary Chieftain-SIRE Rotary Ridger was originally developed by the Scottish Institute of Agricultural Engineering for ridging potatoes. Primary benefits claimed for the design include fewer clods in the ridges for easier harvesting, 15% reduction in rear tractor weight resulting in reduced compaction and clod formation in the furrow bottoms, reduced draft and wheel slippage, and possible use as a cultivator without damaging the crop.
Each ridging unit has a conical hub on each side of a sealed chain case which is mounted on a common pto-driven shaft across the machine frame. Two helically-arranged rows of tines on each hub loosen and shape the soil. Each tine may be individually extended up to five times to compensate for wear. When tines become too short for their original spot, they can be shifted to replace still shorter tines which have become worn. Three and five-rotor models are available with ridge spacings of 28-38 inches.
