1. DESIGN AND EXPERIMENT OF SELF-PROPELLED SYSTEM FOR PADDY FIELD WEEDER BASED ON THE INTERACTION MECHANISM OF WHEEL-SOIL
ABSTRACT Aiming at the low mechanization of paddy field weeding and lack of dedicated agricultural machinery for paddy field weeding in China, a self-propelled system of paddy field weeding machine was designed. The overall structure and working principle of self-propelled system were illustrated and analyzed. The interaction mechanism of wheel-soil during w

2. IMPORTANCE OF CROP PRODUCTIVITY AND EQUIPMENT LIFETIME IN THE STRATEGIC AND TACTICAL MANAGEMENT OF SUGARCANE HARVESTERS
ABSTRACT Recently, Brazilian agriculture and the mechanization process have been improved and developed, particularly in sugarcane cultivation. The developed processes should adopt suitable management practices in terms of the technical, economic, and operational logistical aspects. As a management tool, the present study aimed to measure the impact of the a

3. Impact of local conditions and machine management on grape harvest quality
ABSTRACT: Since its inception approximately 50 years ago, the grape harvester has been one of the machines responsible for the expansion of viticulture in the world. In Spain, harvesters were introduced in the 1990s (there are now approximately 3,000 machines there as of 2017), while they were introduced in Brazil in 2010. Harvest mechanization requires spec

4. Flow Analysis: Looking Back and Forward
Flow analysis changed significantly the way of performing chemical analysis by (i) mechanization of analytical procedures in a continuous flowing stream with minimal sample intercontamination; (ii) analytical measurements without attaining chemical equilibria, thus increasing the applicability of kinetic methods and allowing the exploitation of non-quantitat

6. Demanda de potência do motor hidráulico do extrator primário da colhedora de cana-de-açúcar / Power demand in the hydraulic motor of primary extractor of the sugar cane harvester
The growing demand of sugar cane and the need for agility in the processing of this product, the agricultural sector led to seek cropping systems with greater capacity in the field. However, the sugar cane harvesters still have some critical points depending on the quality of work due to various types of product losses during harvest. Most of the deficiencie

7. Identificação dos fatores críticos da colheita mecanizada de cana-de-açúcar (Saccharum spp.) / The identification of the critical factors of sugarcane (Saccharum spp.) mechanized harvesting
The sugar cane has significant role on Brazilian agribusiness economy. Its sub products are used for electric power generation, fuel production, as raw material for food and chemical industry. On sugarcane production, harvesting is considered as one of the most important operations of the process for it has to attend the raw material demanded by the sugar mi

9. Distúrbios osteomusculares relacionados ao trabalho de operadores da colheita florestal mecanizada / Work-related musculoskeletal disorders of operators of mechanized harvesting
The Repetitive Strain Injury / Work Related Musculoskeletal Disorders (LER / DORT) can arise in any field of activity; just there is a causal factor, ie, functions and jobs that expose workers to risk factors. These risk factors are present in the operator of the harvesting machinery activities. Throughout the workday upper limbs are highly required, necessi

12. DeterminaÃÃo de perdas de frutos nos mecanismos recolhedor e transportador de colhedoras de cafà / Determination of fruit losses at the collector and at the conveyor of the coffee harvesters
The use of the agricultural mechanization is one of the greatest farmers` tools to manage cultures efficiently and to reduce costs. The mechanized harvest is extremely dynamic because every moment new decisions need to be done and modifications in the process need to be accomplished. Therefore, one question to be evaluated is the self-propelling harvester fr
