Abstract

The research aims to design and fabrication of a tractor-mounted animal feed chopping and mixing machine is capable of shredding fresh feed such as cornstalks or napier grass, while also mixing dry feed. The objective of this project is to design, construct, and assess the efficiency of a tractor-mounted. The development concept for the machine focuses base on engineering design on ensuring its durability by using materials readily available in the market. It is designed to be a versatile device capable of both chopping and mixing, utilizing the power from the tractor. The mixing tank has a capacity of 100 kilograms. The researchers tested the machine with a group of dairy farmers in a case study in the small-scale farm of Khon Kaen province, where there were 20 dairy cows. The test results for mixing dry feed revealed an average processing time of 7 minutes for a 100-kilogram batch, which is twice as fast as manual labor. This resulted in a cost reduction in the purchase of concentrated feed, decreasing from 35 Baht per kilogram to 10 Baht per kilogram. Consequently, this optimization yielded substantial annualized savings amounting to 182,142.29 Baht. When considering the investment in the purchase of the forage shredder and mixer for tractor use, the payback period was found to be 0.378 years or approximately 4.54 months.
