Existing plows do not provide high-quality tillage between rows of orchards and vineyards. The purpose the study is to develop justify parameters plow for cultivating soil gardens tractors class 0.9 kN. A design scheme a single-body smooth, rowless plowing garden aisles has been developed. proposed consists movable fixed frame, disc knife, screw body with hostage. research uses laws agricultura...

We studied the drag and lift forces acting on an inclined plate while it is dragged on the surface of a granular media, both in experiment and in numerical simulation. In particular, we investigated the influence of the horizontal velocity of the plate and its angle of attack. We show that a steady wedge of grains is moved in front of the plow and that the lift and drag forces are proportional ...

The effectiveness of manure incorporation in reducing the numbers of adult lesser mealworms emerging from caged-layer poultry manure applied to agricultural fields was examined in summer 2002 and 2004. Incorporation treatments included control (no incorporation), disk (7-cm depth), harrow (15-cm depth), chisel plow (30-cm depth), and moldboard plow (33-cm depth) on silt loam soils in New York s...

the chisel plow is one of the tillage implements utilized to carry out conservation tillage practices; therefore, it is valuable to pay more attention on the force requirement of this implement. to achieve this goal, a theoretical model was developed to calculate draft, specific draft, and drawbar power of a chisel plow. then, results obtained from the developed model were compared with the rep...

drafts of major primary tillage implements were measured in a clay loam soil using a tension loadcell. implements consisted of a moldboard, a disk and a chisel plow each equipped with one tillage unit. a photoelectric speed sensor was used for actual forward speed measurements. during the study, the effects of forward speed and tillage depth on draft requirements were investigated. a general re...

Performance of proper deep tillage can reduce negative effects of soil compaction. The objectives of the research were to determine the effects of deep tillage application on soil physical properties and wheat yield. Therefore, in 2006-2007 an experiment was conducted at Tajarak Agricultural Research Station of Hamedan on a soil with clay loam texture. In this research, four tillage methods wer...
