Estimation of the Remaining Value for Grape Harvesters Based on Second-Hand European Market Online Data

Abstract

Assessing the remaining value (RV) of agricultural machines is essential to compute the depreciation costs, especially in the second-hand market, although previous scientific studies have employed the scrap value as an estimate of RV (10 years of life). Since Brazil, a developing country, is at the very first steps of the process of grape harvest mechanization, it is likely that second-hand grape harvesters will be mainly machines that will be imported and employed for this task. ASABE has developed a methodology to evaluate RV based on an experimental formula that takes into account the auction value, the age and the intensity of annual use. Our work adjusted the RV coefficients for grape harvesters based on the online European market (Spain and France) considering 1290 visited reporting brands, models, ages, hours of use and sale value, refined to 89 unique records. For self-propelled grape harvesters, two types of ownership were identified based on the normal distribution of annual use intensity: private owners (22) and farm service providers (6), with an average RV of 28% and 40% of auction value, respectively. For trailed harvesters, the average RV for a machine age shorter than 13.5 years was 36% of the auction value compared to 12.5% for a life of more than 24 years. The performance of the RV models (R2) based on the formulation of ASABE (American Society of Agricultural and Biological Engineers) amounted to 0.86 and 0.85 for self-propelled and trailed harvesters.
