Effects of chisel plow weight and width, depth of tillage and forward speed on the tillage kinetic parameters in a sandy soil

Authors: Alsuhaibani, S
Description: Tillage is a process of creating a desirable soil condition for seed germination and growth. The tillage of soil is considered to be one of the biggest farm operations as the tillage operation requires the most energy on the farm. Chisel plow is widely used by farmers as a primary tillage tool. Performance data for chisel plow operation is essential in order to reduce the cost of tillage operation. Field experiments were conducted using a fully instrumented MS 3090 tractor to measure the draft of three chisel plows in a sandy soil over wide ranges of plowing depths and forward speeds. The data were measured and recorded using an instrumentation system and data logger. The effects of plowing depth, plow width and weight and forward speeds on draft, unit draft, vertical specific draft, horizontal specific draft and coefficient of pull were evaluated. The results indicated that increasing the plowing depth and/or the forward speed increased the draft, unit draft and vertical specific draft. Also, increasing the plowing depth increased the horizontal specific draft and the coefficient of pull, while increasing the forward speed decreased the horizontal specific draft and the coefficient of pull. Both the width and weight of the blow have significant effects on these parameters. On the average, about 16.6% of the draft force was directed towards cutting the soil and 83.4% was consumed in pulverization of soil particles.
Keywords: tillage, draft, unit draft, specific draft, coefficient of pull, sandy soil, instrumentation, chisel plow.
