The use of software in agriculture allows the achievement of specific objectives in the sector. One of most complex objectives is to choose properly agricultural machines and implements, mainly due to the wide variety of equipment available in the market and the range of tasks and work situations that they are subjected in the field. The objective of this study was to develop a piece of software to calculate the power requirement of farm machines and implements used to carry out field operations, from soil preparation to planting. The software was developed using the PHP language and based on ASAE Standard D497.4 - Agricultural Machinery Management Data, as reference to develop calculations. The software developed allowed the performance of tasks to calculate the demanded power of agricultural machines and implements in a simplified way using the internet.
