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 have collected data using a query and into space to make them aware of the.A real active and aware of the hoes, farmers in the District of Ubon Ratchathani province and selected the most popular dish, the most popular 3 plow first, sorted by popularity, Golden lizard and Crocodile brands include Carl Sehlieper respectively then brought to chemical analysis by Energy Dispersive method ( Spectrometer) study found that all three brands of hoes is a medium-carbon steel from the survey and analysis of the chemical ingredients, so you can choose to update the Crocodile brand with heat treatment because there are Crocodile brand popularity and most carbon percentage 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 Golden Crocodile lizard and Carl Sehlieper, 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 Carl Sehlieper is the alligator, crocodile, lizard and Golden brand after the adjustment, respectively, which corresponds to the value of every strength value. Examine the microstructure with a light microscope. Microstructure of all three brands are the same but the Martensite structure brand Golden lizard is a structure that Martensite detailed result hardness values most. Crocodile brand and brand Sehlieper Carl section is structured as a coarse Martensite and Austenite structure is also with the little alligator brand, after adjustment with heat treatment found that fine Martensite structure. This has resulted in a less hardness, respectively. Cost analysis after adjustment with heat treatment That cost 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.
