Relationship between brand and dealer loyalty in the agricultural equipment market

Agricultural equipment companies intend to understand agriculture producers’ buying behavior by answering questions such as how loyal producers are to brands and dealers, which have an important impact on their profitability. This paper addresses the problem of how loyal agricultural producers are to equipment brands and dealers. Using a combination of cluster analysis and probit models, we identified producers’ behavioral and attitudinal loyalty to brands and dealers and analyzed the factors that explain such loyalty. We also found a strong interdependence between brand and dealer loyalty and the significant value that dealer loyalty adds to the brands. Additionally, we present some management implications of developing brand recognition, understanding producers purchasing behavior, and segmenting producers. This paper’s contributions are the establishment and measurement of an ‘empirical’ definition of brand and dealer loyalty, the identification and quantification of the impact of the explanatory factors of brand and dealer loyalty, and the determination of a dual loyalty relationship between brand and dealer loyalty.

Volume/shear work ratio influence on wear and stress of soil chisel tine modelled by DEM

Agricultural equipment is working in very high-stress conditions. However, it has a significant influence on the wear losses of soil processing parts. Chisel is operating at 30 cm working depth at a maximum of 12 km·h−1 working speed. Due to unpredictable soil conditions, chisel tines suffer high wear losses. It leads to time consumption and cost expenses during the soil preparation period. Wear resistance, and agronomical requirements (working depth, loosening of soil) are the main criteria of agricultural equipment producers. The discrete element method is a solution that simulates soil as sphere shape particles with soil properties. Wear results reveal the change of parts shape, acting forces, and stresses during the simulation in the virtual soil bin. The used Rocky DEM software uses a parameter C (volume/shear work ratio) to describe wear intensity, which varies for different geometry. Chisel tine geometry should be divided into sections with varied parameter C according to stress acting on the surface. The test conditions can be used for future wear analysis of varied tool geometry and protection (sintered tungsten carbide plates, hard-faced surface, etc.) agricultural tools to compare its durability in different soil conditions.

Factors affecting sustainability of agricultural machinery assistance program

One of the Ministry of Agriculture’s efforts to support agricultural development is by providing equipment and machinery assistance. There are many multi-dimensional problems, both technical, socio-cultural, economic, and environmental. This study aimed to analyze the sustainability status of the agricultural equipment and machinery assistance program. This research was conducted in 2020 with the object of the two-wheeled tractor and four-wheeled tractor assistance program in 2018-2019. Research location covers six districts, the selection of site determined by the provinces considered the most successful and the least successful in realizing activities. The sustainability status of the activity program was analyzed using Multidimensional Scale Analysis. The collected data and information through structured questionnaires from 47 institutional respondents and literature studies, both printed and electronic. The results showed that agricultural equipment and machinery assistance program (TR2 and TR4) was less sustainable. The comparison of the MDS value and Monte Carlo’s analysis was 49.93, with an R2 value of 89%. The S-Stress statistical test is still relatively high, namely 0.30 (above 0.25), which means improvements and refinement needs from the implementation aspect. Improvements from various elements are divides into two groups. First, leverage factors that encourage the sustainability and success of the implementation of activities, and the second is the improvement of the performance of TR2 and TR4 beneficiary groups. Policy recommendations for implementing future program activities are a strict selection of potential beneficiaries and improvements in the management aspects of beneficiaries at the farmer level by providing guidance.

OVERVIEW OF DISTANCE ENERGY TRANSMISSION MEANS FOR POWERING AGRICULTURAL MACHINERY TAKING INTO ACCOUNT FACTORS AFFECTING HUMAN SAFETY

This article discusses the issues of autonomous operation of electrical agricultural equipment based on the transmission of electricity over a distance. The main point of this article is that tractors that work in the field are driven by electric motors, with the need to use expensive batteries. The issues of the impact and safety of this technology on the environment and humans are considered. The main problem of the creation, maintenance and operation of transport equipment, including agricultural equipment, is the high cost of maintenance and fuel, which are constantly increasing. In addition, the environmental problem, which has become so acute in recent years, global warming, the fuel crisis and the need to transfer all transport equipment to electric traction, make us look for new ways to solve the problem of environmental pollution and save resources, especially non-renewable energy sources. The use of electrical energy for traction of agricultural machinery that work in the fields or in other industries has been used for a long time, and in the early stages of the development of transport, it was electric transport that occupied the main part, before the invention of the internal combustion engine. Including at the Kharkov Tractor Plant there were developments (and still are), a prototype of the use of electric motors as the main unit for movement. Based on the above, it is obvious that electric traction for transport is obviously environmentally friendly and safe, although there are a number of limitations in this matter as well, but the unresolved problems of the limited use of the storage battery force us to look for new sources of energy. This article proposes to consider the possibility of using electric traction for agricultural machinery with the supply of operating tractors in the fields with the help of a directed electromagnetic wave with its transformation into electrical energy, which will be supplied to the electric motor.

Geometric and kinematic parameters of vibrating knife in the development of cutting machines

The process of cutting with a blade is largely applied in agricultural equipment and is used to process raw materials with different physical and mechanical properties. Nonetheless, the functional relation between the kinematic parameters of a vibroblade and the crucial power parameters of the vibration processing has not yet been studied in great depth so far. This type of studies is essential to create databases for further investigation and design of novel cutting machinery or technologies to ensure effective processing of vibrocutting. Our objective was to obtain the power characteristics of vibrocutting through laboratory experiments [using the example of vibrocutting of common reed (Phragmites australis)] and define the combination of factors (i.e., vibration amplitude, frequency and the blade feeding speed) at the minimum cutting force. The following relation of the blade feeding speed (V) and vibration speed of the toothed blade (Vt) has been established as optimal kinematic regime: K≅0.004. Tests have indicated that use of toothed blades for vibrocutting of the raw products of plant origin offers a greater advantage over the blades with flat edges. An optimal cutting regime, when energy expenses are at a minimum, was ensured with the following parameters of the vibroblade: vibration amplitude: 14 mm, frequency: 33.32 s–1, the blade feeding speed: 7.5×10–3 m.
