Résumé :

Many tractor makes of two-wheel drive (2WD) types are working in the Gezira irrigated agricultural scheme, Sudan. Private individual farmers own most of them. However, information regarding their repair and maintenance costs are insufficient. Moreover, depending on information on repair and maintenance costs from other farming systems or countries is unrealistic. The objectives of this study were to develop power mathematical model to predict repair and maintenance costs for tractors make and their general model for tractors owned by individual private farmers in the Gezira irrigated scheme.

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 sugges

The main task of transport departments is to meet the needs of the main production. The equipment is operated under harsh conditions, as well as after the end of the regulatory period of use and needs to be updated quickly. Despite the timely maintenance and repair of freight rolling stock, frequent failures and increasing repair costs make further operation economically inefficient. When updating the fleet of vehicles, there

In 2009, the National Route 1 Section 1 between km 56.1 and km 61.5, located North East of Paarl in the Western Cape Province of South Africa, was rehabilitated and widened. As part of the rehabilitation and widening contract the downhill truck crawler lane was constructed as an experimental pavement section. This experimental pavement section was constructed with a 50 mm thick Ultra-Thin Continuously Reinforced Concrete Pavement (UTCRCP). Early in 2010 sections of the experimental UTCRCP started to fail and consequently necessitated repair. In October 2014 a service provider was appointed for

Résumé :

The efficiency of the use of high-energy tractors in agriculture is largely determined by the level of preparation for field work, which in turn depends on the completeness of the repair and maintenance work. Various diagnostic tools are used for a non-selective assessment of the general technical condition of internal combustion engines: motor testers, crankcase gas flow meters, etc. Currently, there are no means to assess the technical condition of the gearbox without breaking the power flow. The development of digital diagnostic tools is required to reduce the risk of failures during field

Résumé :

Abstract The operation of farm machinery requires an operator with better operational and technical skills to ensure efficient and effective use of the machinery. These competences are necessary to avoid breakdowns during field operations that can affect machine operating costs. This research aims to evaluate the operators’ competence in the operation and maintenance of farm machinery. Field surveys were conducted in three regencies of the Riau Province, namely Kampar, Indragiri Hulu, and Siak regencies. 63 machine operators were purposively selected and interviewed using structured questionna

Traditional manual and drone coating maintenance methods have problems such as low efficiency, high risk, and uneven spraying, which are difficult to meet the operation and maintenance needs of offshore wind farms.
