The Kelly Diamond Harrow was yet another implement demoed at Ag in Motion last month. The tool is used with the goal of returning crop residue to the soil, accelerating breakdown and improving soil organic carbon levels, all without the depth of most tillage implements.
Each mulching chain link contains an abrasive-resistant concave disc, designed to add weight, strength and cutting ability. The sets typically last 100, 000 acres, according to Kelly. The harrows range in widths from 19.5? to 65?, needing approximately 100 to 375hp, respectively.
