Comparing Acceptability of Three (ICM, SAHAND, New Holland) Combine Brands in West Azerbaijan Province of Iran

Harvesting machines are one of the important sections in agricultural industry and over time, their area of applications has been expanded.There are some important functional factors about their utilization that should be defined to farmers.For comparing the different brands of combinesit is necessary to define some indicators.Work quality, cost per unit, and performance are three main indicators that determine a specific combine's features.The work quality refers to the level of quality that a machine dose a definite duty, the cost per unit shows how much a machine costs to harvest onehectare field and the performance indicator talks about the average time that a machine needs to do its duty and also the dynamism in the farm.These indicators have ever argued among the farmers to answer the differences related to combine brands.To compare two or more than two indicators they are always compared with each other.This analytical method is also useful when the purpose is to find some information in order to choose the best one of things or methods.Comparative analysis has been used in agricultural studies repeatedly.For example, it was used in a study about agricultural mechanization levels in china, the agricultural mechanization levels of 31 provincial areas in China were assessed in order to assess the agricultural mechanization levels of the provincial areas as accurately as possible (Wang et al., 2022).Comparative analysis between some different types of combines to realize performance and optimal costs in order to an evaluation of the economic parameters of combine harvesters in different working conditions is another usage of this kind of analyzing in agricultural machinery (Masek et al., 2015).For assessing the working process of the harvester combines with GPS receiver and grain level sensor in wheat harvesting, the best schedule was detected as a comparative analysis, which could record results in any work regimes (Astanakulov et al., 2021).
