Integrated technology and new generation of multimodule tracked vehicles unit was designed by PIMR- Industrial Institute of Agricultural Engineering in Poznan within the research project WND-POIG.01.03.01-00-164/09. The Tracked Vehicles Unit (TVU) was built as a part of cooperation with Polish firm Hydromega. TVU is dedicated to work on wetlands and should have positive impact on ecology and better environment protection thanks to use of biodegradable oils and lubricants, diesel engine with Stage III emission standard, innovative tracks which have different internal and external speeds during turns. A single-phase technology is designed for harvesting/collecting and transporting biomass (reeds, grass, bushes, small trees) on wetlands, especially these that are located in National Parks and Nature 2000 areas. The TVU is designed to work with different tool modules for cutting, shredding and transporting collected biomass on wetlands. Amphibian type of the TVU’s hulls allows for work in inlands water (rivers, lakes, canals).

The article presents guidelines, developed concepts and the construction of specialized technology tracked vehicle for the transport of biomass on wetlands, implemented within the framework of the development project No. PBS2/B8/11/2013 “Autonomous transport technology of the harvested biomass on protected wetlands" bound removal of unwanted vegetation from protected areas especially national parks, landscape parks and Natura 2000. The design of the new vehicle has been developed by a consortium led by the team of Power Engineering and Dynamics of Agricultural Engineering, BE-PIMR in Poznan. Its task is to find a solution that would significantly increase the efficiency of the process of obtaining biomass, taking into account the autonomy of action of the resulting structure. This technology will be one of the important links of the system built for the maintenance and improvement of biodiversity in protected areas.

This paper presents a new concept of the manipulator of the specialized tracked vehicle, designed within the project “WND- POIG.01.03.01-00-164/09 & UOD-DEM-1-145/011”, to be applied for conservation of the protected wetlands. The flail mower, cutting disk for trunks of the trees and/or new version of cutting head are to be interchangeably fitted at the end of the manipulator. It should be more functional in use and more efficient in cutting and removing small trees or bushes, or shredding them on spot. The new cutting head, described in this paper is dedicated to remove and transport branches of bushes, as well as single small trees with a diameter up to 140 mm and weight up 400 kgs on 3.2 m length arm. The paper presents the results of the kinetostatics and strength analysis of the virtual model of the new version of the manipulator. Real model of the new manipulator will be made from the steel S355 and its mass without tools should be around 350 kgs. The manipulator will be tested during field tests that are planned in the summer 2015.

The aim of the paper was to propose conception of autonomous robot for sowing and wide row planting. Autonomous work of the robot in range of traction and agronomic processes will be implemented on the basis of data from a many sensors (cameras, sensors position, sensors distance, and others). Positive test results will allow for the use of the robot in organic crops requiring mechanical removal of weeds or in crops with application of selective liquid agrochemicals limited to the minimum The use of a vision system, based on the map coordinates of the position of the sown seeds , will allow for their care on an early stage of plant development. The applicability of the robot to onerous work in organic farming may encourage farmers to discontinue the use of herbicides in crops include sugar beet, corn, etc.

The article concern to the scientific and research works related to the development of mechatronic control system of sowing unit in the tilling-and-sowing combined machine. The essence of the project is the use in the combined machine of innovative control system responsible for the seeding process. The system will control the work of seeding unit (drive) and will maintain a predetermined depth of seeds sowing.

Grooved or pinned units used in seeding are characterized by variability in application rate as a function of the changing conditions of work (e.g. on the slopes). In the proposed solution, on the basis of the identification of the sensitivity of the sowing machine on the changing conditions of work, the control algorithm will be developed, which after application to a controllable propulsion system equipped with the necessary sensors will eliminate inaccurate dosing. Project/Grant No K2/IN2/64/182979 is co-financed from the budget allocated for science.

Many people are exposed to whole-body vibration (WBV) in their occupational lives especially drivers of vehicles such as tractor and trucks. The vibration-induced injuries or disorders in a substructure of human system are primarily associated with the vibration power absorption distributed in that substructure. Absorbed power is defined as the power dissipated in a mechanical system as a result of an applied force. The article presents the results of dynamic load analysis of the tractor mower set. The amount of absorbed power by the tractor’s operator, based on physical models have been calcu- lated, as a function of operating speed of tractor mower set.
