Abstract

In the original publication of Coleman (2019), the reported tillage parameters and implement definition for the rotary hoe were based on a power take off (PTO)-driven cultivator; however, the presented energy consumption calculations were for the ground-driven implement. The name rotary hoe is used for two significantly different implements: i) a PTO-driven cultivator commonly used in the UK and Australia for aggressive soil disturbance with slow work rates, and ii) a ground-driven implement used for shallow cultivation in the US with high work rates. (Figure Presented). (Table Presented). fast movement over large fields, with the ground-driven wheels typically measuring 45 to 53 cm in diameter. The authors apologize for this error.
