Abstract

Costs of maintenance on combines are a subject of interest thus it constitute a large investment and cost for the individual farmer. Therefore it is important to have up to date knowledge and the right facts to be able to do reliable calculations on one of the largest investments for a farmer. The aim of this study was to compare costs of maintenance on combine/threshingmachine with the computer program for advising environmental issues in agriculture, STANK. Interviews took place and data were collected by handing out questionnaires to 20 farmers. A similar study conducted by Neuman (2003) investigated costs of maintenance and compared these with STANK. The results of this study have also been compared and examined related to data from SLA - Skogs och Lantarbetsgivarförbundet. The result shows that 18 out of 20 combines were given a higher cost of maintenance when using STANK compared to the numbers in this study. The total cost of maintenance in STANK and this study shows that STANK were in average 49, 4 % higher. While comparing yearly using hours and cost of maintenance we found that the cost raised with increased using hours, but there are no proportional connection between increased yearly using hours and increased labour/own work. While checking the condition between costs of maintenance and machine-age the study could not see that the cost raised with machine age. The study was used for a different model of calculation where we calculated with the cost, SEK/foot cutting width and year. This model of calculation was used when comparing the cost SEK/foot cutting width and year for SLA and the study. This model of calculation gave a better result than STANK did. The model gave a deviation of 32,8 %. Our conclusions • The equation in STANK overrated the cost of maintenance by 49,4%. • There were only some tendency of correlation between cost of maintenance and yearly use. • There is no relation between the cost of maintenance and the age of the machine. • The maintenance should not be connected to using hours and the cost of buying an equal new machine today. • In our study we found that it is better to use a yearly cost in SEK/foot when calculating the cost of maintenance on combines. However, this is a model suitable for our study but this might not work for a general use.
