Performance evaluation of tractor drawn rotavator for dry and wet land preparation

This research paper gives details about the performance of the tractor-drawn rotavator for dry and wet land preparation in the farmer's field. The rotary tiller is used as a primary as well as secondary tillage implement and having three different shapes of the blade. The L-shaped blades were attached to the rotavator’s rotor to evaluate the performance. The wheel slippage was found 1.22 to 2.10% and 3.90 to 5.88% for the dry land conditions and wetland conditions, respectively. When the moisture in the soil increases the wheel slippage also increased. The research found that the puddling index varies indirectly proportional to the speed of operation. The study revealed that the average wheel slippage 3.90, 4.07, and 5.58% were found at an average speed of operation 1.5, 2.0, and 2.5 km/h, respectively on wet land field conditions.
