A study was carried out on three tractors of same make and model to know the realistic information on repair and maintenance cost which is directly dependent on the tractor utilization in various operations and handling by the operators for a period of eleven years, i.e., August, 1988 to July, 1999. All the studied tractors were purchased on same date. The tractors T1, T2 & T3 were operated for 5976 hours, 8168 hours and 9670 House, respectively. These tractors were mainly engaged for seed bed preparation, land development, threshing, /shelling and transportation purposes. The study suggests that an experienced and sincere driver can save the repair-maintenance cost and will also add in enhancing the life of tractor.

This study aims to examine attributes preferred by farmers of Parsa district for choosing four-wheel tractors. This study presents how farmers perceived their effectiveness based on common attributes of tractors like origin, brand, fuel consumption, horsepower, price, availability of spare parts, and their repair and maintenance. The study is quantitative and based on primary data. A non-probabilistic sampling technique was used with a sample size of 85. Conjoint analysis was applied to estimate part worth utility value, utility range and ranking the attributes of four-wheel tractor. The result show that farmers gave highest preference to fuel consumption with respect to highest utility value following horsepower, origin, price, availability of spare parts and repair and maintenance. Similarly, results show that branded and low-price tractor whose spare parts can be found easily in local market along with assured repair and maintenance facility available from authorised agency is preferred by farmers. Horsepower has been important attributes for tractorselection, where farmers are mostly preferring tractors having horsepower greater than 45 hp. This study findings will provide valuable tools and a basic framework for suppliers and manufacturers for evaluating their market efficiency and preparing strategies for promoting four-wheel tractors.

Purpose. The purpose of the study is to optimize production processes and minimize maintenance costs for the machine-tractor park in agro-industrial production. Methods. The research is based on the calculations of maintenance point (MTP) productivity for mono-subject mono-technological specialization (specialized posts) and the theoretical provisions for the calculation of mono-subject poly-technological specialization (in a joint stream) developed by us. These provisions are developed for the given structure of the inter-repair cycle and normative average annual working hours of tractors. Various maintenance of HTZ tractors can be performed both in a common flow (poly-technological specialization) and on specialized MPT (mono-technological specialization), which are selected from pre-synthesized parametric series. Results. The development of multi-subject specialization, both multi-subject and poly-technological, is extremely important for ensuring effective processes of technical service and they are based on studies of the organizational-technological compatibility of technological processes (TPs). Organizational-technological compatibility (OTS) characterizes both necessary and sufficient conditions for combining different TPs of repair or maintenance in a common flow. Conclusions. It is more expedient to combine maintenance processes in a common flow, first of all, not on the basis of an objective feature – the similarity of the construction of tractors, but on a technological basis – the type of maintenance. A comparative analysis of all types of maintenance carried out at stationary posts in a joint flow gives reasons to recommend maintenance in a joint flow, when the number of HTZ-16131 tractors in the service area does not exceed 484 units, and their average service life is 1500 motos hours Keywords: HTZ tractors, maintenance, technological process, specialization, compatibility, post.

A survey has been undertaken to look into the causes of tractor breakdowns on field operations and the main constraints associated with repair and maintenance, and to recommend a solution to the problems in Riau Province. The owners of sixty-two small tractors were interviewed, from three regencies chosen of the Province in 2003. As a result, the working capacity of the tractors was relatively high and the average annual use was relatively low compared to the national average. Most tractor operators did not have sufficient skill to operate tractors. The tractor breakdowns resulted from operators’ mistakes, fuel and oil defilement, rough field conditions, poor maintenance, intense use, and factory design. Inadequate repair shops, a lack of spare parts, and a shortage of mechanics in the local vicinity were the main factors curbing tractor repair. It was also found that inadequate finances led many farmers to ignore tractor maintenance. These suggest that tractor operators should be well trained and tractor-supporting facilities should be provided in rural areas. A mechanical extension officer and credit options should be made available for farmers.

Abstract Maintenance plays an important role in reliability, availability, production quality, risk reduction, efficiency increasing, equipment security, etc. Therefore, maintenance strategies have a special position in industry. Simultaneously, effect of tractor power is considerable in agriculture; therefore, it is necessary to pay attention to the probability of failure, repair time and causes of malfunctioning. Many variables, including cost, depreciation, breakdowns, annual performance, etc., have major impact on tselection of a maintenance strategy. Therefore, these variables were determined with the help of experts. Subsequently, these were clustered into several main criteria groups on the basis of factor analysis using SPSS software. Obtained results were used in a hierarchical structure to suggest the most appropriate maintenance strategy based on pair-wise comparison. According to the regional conditions and available facilities, results showed that the proactive maintenance strategy proved to be the best suggested option from four maintain strategies, namely emergency maintenance, proactive maintenance, preventive maintenance, predictive maintenance.

The paper presents an approach for deriving a mathematical model that predict repair and maintenance (R&M) cost of farm tractors in The Gambia. As John Deere (JD) tractors are widely used by Gambian farmers, a study was conducted to predict accumulated repair & maintenance costs (Y) of the two-wheel drive (2WD) JD-5403 tractor based on accumulated working hours (X). In order to determine the mathematical model for the studied tractor, regression analysis using knowledge based analytical software (SPSS STATISTICS 21 and Excel 2016 version) was performed on the calculated data generating five regression models: linear, logarithmic, polynomial, power and exponential. The statistical results showed that the polynomial model gave better cost prediction with higher confidence and less variation than other models. Finally, it was established that repair and maintenance cost increased with an increase in working hours of JD-5403 tractor.

M.Tech. (Mechanical Engineering)
The dissertation documents the design project of a low cost tractor prototype to be manufactured locally. The design and manufacturing of a South African tractor is part of a larger project namely “Roads for Africa” initiated by the local company Terragrader (Pty) Ltd. The design parameters of the tractor were established based on the power needs of a dirt roads refurbishing machine the “Terragrader” manufactured by the same company. Although the tractor was designed to power the Terragrader machine, it can successfully be used to power different agricultural machines or transport. The designed South African tractor has to be versatile, easy to adapt to different working conditions. The design aim is to produce a tractor able to provide adequate power at a cost of about R500 000, whereas the market offers similar machine at a much higher price starting from about R800 000. The concept of a South African tractor is not new but due to import options, there was never a known / well established South African brand. Due to the shrinkage of the South African mechanical manufacturing industry by nearly 40 % in the last years, a successful tractor design and manufacturing will contribute toward the much needed job creation. Due to its complexity the project is a combination of newly designed parts and outsourced components. The integration of design establishes the layout of the tractor with the aid of virtual 3D solid modeling.

Abstract The inspection of power generators is a critical activity that will grow in importance during the next decades as operators are seeking solutions to continuously reduce outage duration and improve availability and reliability of the equipment. Automatic and systematic data collection on the status of health of the generator enables the possibility to implement predictive diagnostic/maintenance strategies and reduce the downtime due to repair activities. In this context robotic inspections play a crucial role since they allow a quick and efficient method to acquire data on the status of the generator. This paper describes an innovative robotic system that, thanks to a novel multi-sensor analysis method, is able to inspect and evaluate the overall status of power generators. The detection system, which is located on board a crawler robot, consists of inspection cameras, a micro-hammering system that is able to detect the acoustic response of fixing components of the generator bars and an Electromagnetic Core Imperfection Detection (EL-CID) sensor, which aims to detect insulation failures. Additionally, there is a description of how the robot has been designed to be adaptable to a wide range of different generators, and how it was tested and validated in the field.
