This project is a study on the mechanical properties and use of agricultural equipment (shovel) of Ubon Ratchathani province, farmers, and the objective is to study and improve the mechanical properties of agricultural equipment (shovel) group to collect data by using a query, and for.Hot Plains to the actual usage, and aware of the hoes, farmers in the District of Ubon Ratchathani province and selected the most popular dish plow most popular top 3 sorted by popularity include lizards, crocodiles and gold seal brands respectively, then taken to analyze the chemical way (Ene.Rgy Dispersive Spectrometer) study found that all three brands of hoes is a medium-carbon steel from the survey and analysis of the chemical ingredients, so select the crocodile brand to improve with heat treatment because the crocodile brand has the highest popularity and have signed the most carbon when the updated, better mechanical properties. The lifetime of a hoe it longer worth the price. Then bring to the study of the mechanical properties by hardness test (Hardness Test) tests the hardness of shovel 3 brands of the experimental results is a strong brand is the brand most lizards, and alligators eye check gold respectively. After update with heat treatment makes the crocodile brand hoes with more hardness values. From the impact resistance test of all three brands are brands hoes resistance against shocks most is brand of Catania is the crocodile, lizard and crocodile brands gold after the adjustment, respectively. Examine the microstructure with a light microscope. Microstructure of all three brands are the same but the Martensite structure and brands of lizards as Martensite structure detailed result hardness values most. Alligator brand and brand, part of Catania with a coarse Martensite structure. This has resulted in a less hardness, respectively. Crocodile brand, after adjustment with heat treatment found that fine Martensite structure. Cost analysis after adjustment with heat treatment Be said that the cost of the shovel with the price increasing but compared to the price of a shovel before updating it with heat treatment and then do not differ much in price that farmers can afford to buy a shovel.
