The study looked at how agricultural machinery is used to support rice farming in Grobogan District. They wanted to see which machines were being used and how well they were managed. The researchers found that two-wheeled tractors and Big combine harvesters were commonly used, while other machines like trans planters and hand sprayers were not being used much. The best management of machinery was seen at the military district command, where machines were lent out carefully and borrowers had to keep them clean and undamaged. Overall, the study showed that certain machines were more useful for rice farming in the area, while others were not being used effectively due to not matching the local conditions.
