Active-passive and passive-passive configurations of combined tillage implements for improved tillage and tractive performance: A review

Proper selection of energy-efficient agricultural machinery helps to reduce drudgery, increase cropping intensity and time required for field preparation. With conventional tillage implements, multiple passes are obtain desired seedbed which soil compaction due repeated movement tractor in field. combined implements two or more fuel energy In this paper, various researches on active-passive passive-passive configurations have been discussed along with their working principles. It was found that these were associated less draft, specific energy, tire slippage compared provides a sound basis using them suitable engine power improve the utilization tractors. Hence, use could help compaction, labour, cost as well save preparing seedbed. More analytical studies classical approaches needed predict requirements from knowledge individual proper matching tractor-implement also develop decision support systems. Considering promising outcomes, they will emerge effective tools mechanization.
