Within a continuous development of mobile agricultural machinery the application and further introduction of electronic controls is offering the fare most potential for working processes optimization. The article gives an introduction to tractor and implement controls, especially targeting implement guided tractor control, underlined with two executed examples for this advanced control design. ...

We describe the development of the Safe Tractor Assessment and Rating System (STARS), a design-based tractor safety rating system that can be applied to new or used tractors to provide an objective assessment of their inherent safety features. A predictive rating system model, based on technical inspection, was used. Key principles underlying the system included the potential for design feature...

Timber transport in the forest is a very complex operation, and expensive from an energy point of view. Furthermore, in some cases, this operation can be very difficult and dangerous in unfavorable conditions of the road surface, which mainly occur in winter (frozen ground) and in spring (muddy ground). The goal of this study was to develop an innovative transmission hydraulic control system fo...

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 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...

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 ...
