  • The Farm Tractor in the Forest" Is a Manual for Woodlot Owners and Small Scale Woods Contractors
    The Form Troctor in the Forest "The Farm Tractor in the Forest" is a manual for woodlot owners and small scale woods contractors. It outlines the type of modifica• tions and auxiliary equipment that may be needed if a farm tractor is to be useful in a forestry operation. Guidelines for planning of forestry operations and safe work techniques are also provided. The last sections of the book cover the economic aspects of farm- tractor-logging and provide examples of how to calculate costs to compare different logging systems. The original version of this book was printed in Sweden. Illustra• tions and most references reflect current Swedish conditions. However, in some places minor changes have been made in the English version to reflect conditions in North America. ® The National Board of Forestry, Sweden Written by: Milton Nilsson illustrations: Nils Forshed Cover photo: Milton Nilsson Reference group: Thorsten Andersson Karl-Gunnar Lindqvist Bertil Svensson Project leader: Karl-Goran Enander Bengt Pettersson Editor: Bengt Pettersson English translation: Forest Extension Service N.B.

  • Modeling of Tractor Fuel Consumption
    energies Article Modeling of Tractor Fuel Consumption Bronisław Andrzej Kolator Faculty of Technical Sciences, University of Warmia and Mazury in Olsztyn, Oczapowskiego 11 Street, 10-719 Olsztyn, Poland; [email protected] Abstract: In this paper, the energy diagnostic of tractor performance consists in evaluating the energy (fuel consumption per hectare—dm3 ha−1) for a given agricultural operation and in combining it with working capacity, also called productivity (area productivity—ha h−1). One of the methods of solving this problem is the identification of the functioning process of the machine unit. A model of the process of the machine unit performance was developed, considering the operation of the rear linkage system of the implement with the force control adjustment system. In order to analyze the system, a mathematical model of the system function was built: tractor-implement-soil, defining the physical connections and interdependencies between the individual subsystems of the system. Based on this model, a simulation model was developed and implemented in the Matlab/Simulink environment. The Simulink package was used to test the performance of the machine set. The efficiency indicators according to the adopted criteria were calculated in the evaluation block. To evaluate the process, the technical and operational parameters of the tractor, the type and parameters of the tool, and soil properties were taken into account. The results of simulation studies obtained on a validated model are consistent with experimental data from appropriate soil conditions. Keywords: tractor; fuel efficiency; total efficiency; simulation model; three-point hitch; draft control Citation: Kolator, B.A. Modeling of Tractor Fuel Consumption.

However, tractors have qualitative and quantitative attributes that must be simultaneously integrated into the evaluation process. This article reports a hybrid and multi-attribute approach to assessing a set of agricultural tractors based on AHP-TOPSIS. To identify the attributes in the model, a survey including eighteen attributes was given to agricultural machinery salesmen and farmers for determining their importance. The list of attributes was presented to a decision group for a case of study, and their importance was estimated using AHP and integrated into the TOPSIS technique.

  • Transmission (Mechanics) - Wikipedia 8/28/20, 119 PM
    Transmission (mechanics) - Wikipedia 8/28/20, 119 PM Transmission (mechanics) A transmission is a machine in a power transmission system, which provides controlled application of the power. Often the term 5 speed transmission refers simply to the gearbox that uses gears and gear trains to provide speed and torque conversions from a rotating power source to another device.[1][2] In British English, the term transmission refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive), differential, and final drive shafts. In American English, however, the term refers more specifically to the gearbox alone, and detailed Single stage gear reducer usage differs.[note 1] The most common use is in motor vehicles, where the transmission adapts the output of the internal combustion engine to the drive wheels. Such engines need to operate at a relatively high rotational speed, which is inappropriate for starting, stopping, and slower travel. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted. Often, a transmission has multiple gear ratios (or simply "gears") with the ability to switch between them as speed varies. This switching may be done manually (by the operator) or automatically. Directional (forward and reverse) control may also be provided. Single-ratio transmissions also exist, which simply change the speed and torque (and sometimes direction) of motor output. In motor vehicles, the transmission generally is connected to the engine crankshaft via a flywheel or clutch or fluid coupling, partly because internal combustion engines cannot run below a particular speed.
