A portable data acquisition system, using a laptop computer, was developed to monitor performancc of soil-engaging implements during field operation. The vertical and horizontal forces exerto:l by th...

In order to reduce herbicide application an intelligent sprayer boom is being developed. It only sprays with herbicides if the weed infestation exceeds a certain weed control threshold. The estimation of leaf cover of weeds through image analysis is a prerequisite for the weed management model of the intelligent sprayer boom. Destructive and human perception methods of leaf cover estimation are...

In this study which has been conducted in Akçasu Forest Range District of Devrek Forest Directorate; 3 methods (weed control with labourer power, cover removal with Hitachi F20 Excavator, and weed control with agricultural equipment mounted on a Ferguson 240S agriculture tractor) were utilized in weed control efforts in regeneration of degraded oriental beech forests have been compared. In this...

BACKGROUND: At considering the issues of crawler tractors interaction with soil determining factor is time-varying impact loads on layer, its stressed and strained state, which, in turn, directly depends stress-strain properties. The properties assessment should be carried out a rheological approach, which allows to explain many phenomena processes develop new high technologies terms criterion ...

Tractor hydraulic power is used on a wide range of agricultural implements; however, the availability of operational hydraulic data at points other than full engine throttle position is limited. Operators could utilize this hydraulic data to maximize field efficiency and minimize machinery costs when determining suitable machinery for field operations. A field usable hydraulic test apparatus ca...

A smart sprayer comprises a detection system and a chemical spraying system. In this study, the development status and challenges of the detection systems of smart sprayers are discussed along with perspectives on these technologies. The detection system of a smart sprayer is used to collect information on target areas and make spraying decisions. The spraying system controls sprayer operation....

The objective of the research was to assess the outcomes on the spray patterns produced by the different feasible adjustments of two different air blast sprayers and one mist blower sprayer, commonly employed for treatments to Apulian “tendone” vineyards. The spray profiles of these machines and the respective refinements affected by the alteration of the available adjusting devices were evalua...

The purpose of this research was to developed a program in visual basic software for predicting tractor implement performance combination. A conventional tillage system with mounted mouldboard plough and three bottoms used collect data from Chery (Model RM750) four-wheel drive. soil texture class were determined laboratory. Soil cone index value measured using SpotOn digital compaction meter. o...

Prasanna Kumar G.V. (2015): Geometric performance parameters of three-point hitch linkage system of a 2WD Indian tractor. Res. Agr. Eng., 61: 47–53. Geometric performance parameters of three-point hitch system of a most sold model of a 2-wheel drive Indian tractor were determined by generating the path of upper and lower hitch points by kinematic linkage analysis. At various locations of pivot ...
