Abstract:
Abstract Rotary tillers often have shallow plowing depth and serious leakage problems in the specific working process, resulting in a decrease in the rate of soil breaking and stubble breaking, causing damage to mechanical devices. In this paper, we conducted a field test on the popular self-propelled rotary tiller to obtain the changes in the operating Indexes of various types of knife roller operation with time under three types of tillage environments; we conducted a force analysis and finite element analysis on the IT245 rotary tiller to obtain the stress effect and deformation of the rota

Abstract:
Rotary tillers implements are now projected as important tillage machinery for better seedbed preparation; however the ordinary rotavator being in line with the tractor center line at the rear cannot be used in orchards due to the hindrance posed due to narrow space between the plants. Therefore, the concept of a rotary offset tiller in other words orchard tillers was proposed, which could perform finer intercultural operation between the plants. Since there are some models of Indians and Foreign made rotary offset tiller available and their work quality parameter significantly plays a crucial

Abstract:
A rotary tiller or rotavator is active tillage equipment used to prepare farmland for sowing seeds, weeding, mixing manure and fertiliser into the soil, crushing soil blocks, etc. Compared with conventional farming, the advantages of this equipment are rapid seedbed preparation and reduced draught. Nowadays, the utilisation rate of rotary tillers has increased. However, the blades are the key component that engages with the soil in the rotary tiller. These blades interact with the soil differently from ordinary ploughs and bear impact loads and high frictional forces, which eventually generate

To reduce the power consumption of rotary tillage and enhance the operational quality of rotary tillage, a rotary blade that imitates the surface of a pufferfish was designed through reverse engineering.

Abstract. Submerged reverse rotary tillage was presented decades ago as a way to save energy in deep tillage, but its application was limited because it throws the tilled soil forward. The forward-thrown soil gets re-tilled, resulting in wasted energy. To understand the soil throwing process during reverse rotary tillage, a theoretical soil throwing model was established, but that model was investigated by few tests. How soil is thrown by a submerged reverse rotary tillage system is, as yet, not clear. To optimally design a submerged reverse rotary tiller, it is necessary to reveal how soil is

The goal of the project was to enhance the period of weed growth prior to seeding in order to reduce weed emergence and weed competition after the crop has been planted. Weed growth was stimulated using either light tillage or by applying nitrogen fertilizer early in the spring. Light disturbance significantly increased pre-seed weed emergence while early applied nitrogen did not appear to have an effect. Post seeding weed emergence levels and weed biomass were similar among the light tillage and early nitrogen treatments. Therefore the goal of decreasing weed competition after seeding was not

This chapter describes the Rotating-Tilted-Lines illusion , which is a new motion illusion that arises in a circular pattern composed by black, radial lines tilted to the right and presented on a white background. When one approaches the stimulus pattern, the radial lines appear to rotate in the counterclockwise direction, whereas when one recedes from it, they appear to rotate clockwise. It is the simplest pattern able to elicit illusory rotatory motion in presence of physical radial expansion.
