| چکیده | ||
| در این تحقیق، اثر سرعت پیشروی در چهار سطح (8/1، 3/2، 9/2 و 5/3 کیلومتر بر ساعت)، عمق خاکورزی در سه سطح (30، 40 و 50 سانتیمتر) و باله در دو سطح (بدون باله و بالهدار) بر نیروی کششی، سطح مقطع شیار ایجاد شده در خاک و مقاومت ویژه گاوآهن پارا بررسی شد. نتایج نشان داد که تأثیر باله و عمق بر پارامترها به طور معنیداری بیشتر از سرعت پیشروی است. افزایش سرعت به افزایش نیروی کششی و مقاومت ویژه اما کاهش سطح مقطع شیار انجامید. افزایش عمق و افزودن باله به افزایش نیروی کششی، سطح مقطع شیار و مقاومت ویژه منجر شد. انتقال گاوآهن پارای بالهدار به حداقل عمق زیر سختلایه به طور معنیداری موجب کاهش مقاومت ویژه گردید. نتایج توصیه میکند که از سرعت کمتر، کمترین عمقی که بتوان سختلایه را شکست و باله استفاده شود. مدل رگرسیونی شامل سرعت، عمق و عرض باله به منظور پیشبینی نیروی کششی ارائه گردید. | ||

| چکیده [English] | ||
| In this research, the effect of forward speed at four levels (1.8, 2.3, 2.9 and 3.5 km/h), tillage depth at three levels (30, 40 and 50 cm) and wing at two levels (winged and no-winged tines) were investigated on the draft requirement, soil disturbance area and specific draft of Paraplow. The results revealed that the effect of depth and wing was more than forward speed on the studied parameters, significantly. Increasing forward speed increased draft requirement and specific draft but decreased disturbance area. Increasing depth and adding wing led to increase draft requirement, disturbance area and specific draft. Transfering winged paraplow to under the hardpan decreased specific draft, significantly. The results recommended that using lower speed, minimum depth for hardpan breakage and wing will be better. A regression model included the speed, depth and wing width was developed to predict the draft requirement. | ||
