“…The actual field results shows that the percentage improvement in the length of hardfacing ploughshares with respect to regular ploughshare were found to be 2.272%, 12.5%, and 25% for H1, VB, and LH550 ploughshares, respectively. Furthermore, H2 hardfaced ploughshares were observed higher length loss (4.255%) in than the regular ploughshare in same field conditions it was reported by Owsiak, 42 reported that the wear of ploughshare points working inside the wheel track was higher than the outer wheel track points.…”

Generally, during soil tillage it is seen that farmers complain about the higher wear rate of agricultural implement. Wear of cultivator shovels is one of the major problem faced by farmers in the agricultural sector. Any improvement in the life of ploughshares will be of great significance to the farming sector. The aim of the present work is to improve the life of cultivator shovels by way of hardfacings by shielded metal arc welding process. The wear behavior of bare (EN-47 steel) and four different hardfacings (H1, H2, VB, and LH550) having different chromium content (i.e. 0.86% Cr, 2.4% Cr, 3.19% Cr, and 6.72% Cr) were investigated with regard to wear behavior. A test was conducted on a 60 ha area of the wheat field after harvesting (latitude 30.121207, longitude 75.009159). During the time of cultivation soil was dry and hard. Wear behavior of bare and hardfaced steel was analyzed in terms of weight loss (g/ha) and by wear resistance indices. Techniques like optical microscopy, scanning electron microscopy, X-ray diffraction analysis were used for testing. The hardfaced steel has shown significantly better wear behavior in comparison to bare steel except H2. Wear of ploughshares according to cultivated area was found to be 3.459 g/ha for regular, 3.41 g/ha for H1, 4.267 g/ha for H2, 2.553 g/ha for VB, and 1.993 g/ha for LH550 hardfacing. The WRIs of different hardfacings, i.e. H1, H2, VB, and LH550 were found to be 1.014, 0.81, 1.354, and 1.735.

“…In controlled-traffic systems, energy savings are comprised of savings from fewer operations, shallower depths of operation, and lower draft requirements of the involved implement. Moreover, operation of tillage implements in non-compacted fields resulted in an increase of implement durability due to less abrasion from lower density soils (Owsiak, 1999).…”

Soil compaction causes deleterious effects on physical and mechanical proprieties of agricultural soils. In order to investigate the effect of soil moisture content and tractor wheeling intensity on traffic-induced soil compaction, this study was carried out on a field with clay loam soil. Soil dry bulk density and hydraulic conductivity as well as emergence percentage of corn seedlings and dry mass of the sampled mature plants were considered the dependent variables of the experiment. Independent variables consisted of soil moisture content with five levels (12, 15, 17, 19, and 21%), traffic intensity with three levels (four, two, and zero passes of tractor wheel (tractor model: John Deere 3350) from the entire area of the plot), and soil sampling depth with three levels (0-10, 10-20, and 20-30 cm). According to the results of this study, gradual increase in soil water content generally resulted in an increase in soil bulk density; moreover, increasing the tractor wheeling intensity from 0 to 4 passes increased bulk density by 13%. Furthermore, the driest soil water content had the highest and the wettest soil water content had the lowest emergence percentage of corn seedlings among the treatments; moreover, traffic intensity treatment inversely affected the emergence percentage of corn seedlings and the dry mass of mature plants. To sum up, these results indicate that, for improving water permeability and reducing dry bulk density of the examined clay loam soil, as well as better emergence of corn seedlings and ultimately increasing crop yield, it is recommended to avoid wheeling when soil moisture content is high, reduce the number of machinery wheel passes from the farm as low as possible, and restrict the wheel passes to fixed strips along the field, whenever possible.

“…Numerous scientific reports have considered the relationship between the intensity of abrasive wear and the soil moisture [ 8 , 9 , 10 , 11 ], the size and shape of abrasive grains [ 12 , 13 , 14 , 15 ], and soil pH [ 16 , 17 , 18 ]. In addition, the subject of interest of many authors has been the study of the impact of the variability of soil and agrotechnical conditions on the intensity of abrasive wear of various working elements [ 10 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ]. In the mentioned scientific research, the authors focused on specified soil and cultivation aspects, which are not the only factors influencing the durability and reliability of the working elements operating in the soil.…”

The Evaluation of the Effectiveness of Reinforcement by Cemented-Carbide Plates in Two Design Variants of the Chisels Intended for Cultivation–Sowing Aggregates

Field tribological tests of two design variants of chisels used in the teeth of a cultivation-sowing unit were carried out in this research. A characteristic feature of the first variant of chisels was the reinforcement of their contact surface and almost the entire rake surface by plates made of cemented carbides. On the other hand, the second variant of chisels was reinforced only in the area of the blade by two plates made of cemented carbides, soldered on the rake face of the elements. The use of the first variant of chisels contributed to a significant reduction in the wear rate of elements, especially in terms of thickness and width loss. Effective reinforcement of the rake face, with relatively lower resistance to length reduction in the elements, raises doubts as to the validity of the use of cemented-carbide plates on almost the entire length of their rake face, because the applied variant of chisels contributed to a significantly higher price. However, the second variant of chisels effectively limited the intensity of the loss of the length of the elements, and the cause of the loss of their usefulness as part of the base material wear. It was found that the main wear mechanism of the cemented-carbide plates consisted of matrix removal under the influence of the finest fraction of the soil, which weakened the embedding of carbides, and then crushing or chipping of carbide grains from the matrix, whereas the dominant wear mechanisms of martensitic steel were grooving and micro-cutting.
