“…Under such conditions, predicting the required torque can be very important for designers, as well as for other experts who use such machines in the field. The model constructed was tested in experiments conducted in soil channels, which confirmed its reliability [9].…”

“…Article [9] hypothesizes that the methods used to predict the forces on the soil that cut narrow paws can be applied to the rotary deep loosener. However, when using these methods, it is necessary to take into account the position of the working element in the soil and take into account the features associa-ted with the rotary loosener.…”

This paper reports a study aimed at increasing the intensity of grinding of the stems of coarse-stemmed crops by establishing the influence of the orientation of the cutting edge of the cutter-shredder knives on the quality of the technological grinding operations. Analytical dependences of the planar movement of the roller-shredder were established and it was determined that for rollers with knives, the cutting edge of which is directed in the direction opposite to the direction of rotation: – exceeding the value of the vertical components of the total forces of resistance of the knives, which made it possible to increase the values of forces, and, as a result, more intensive destruction of the layer of plant remains; – exceeding the values of the driving force of the knives based on the dependence of the driving force on structural and kinematic parameters (roller weight, drum radius, blade height, blade inclination angle, acceleration). Experimental studies have established an excess of up to 20 % of the quality indicators of milling sunflower and corn stems with roller knives, the cutting edge of which is directed in the direction opposite to the direction of rotation. The average number of crushed pieces of corn stalks in the range of less than 50 mm is 13.6 % higher in the combined unit, the cutter blades of which are directed with the cutting edge in the direction opposite to the direction of rotation. It was established that with zero and 3.92 kN (400 kg) additional loading, an increase in speed from 7.45 km/h to 13.6 km/h leads to a decrease in the values of the average traction resistance. The highest value of traction resistance was set at a speed of 13.6 km/h and an additional load of 7.84 kN (800 kg). The lowest value of traction resistance was established at zero additional load and a speed of 22.0 km/h, which is 21.5 % less than at a speed of 7.45 km/h and 14.1 % less than at a speed of 13.6 km/h.

“…However, they all enable experiments to be conducted for small tools which make up a larger structure [ 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. Such structural diversity of test stands makes it possible to measure characteristic parameters for the given agricultural machine at the selected nodes [ 21 , 22 , 23 , 24 , 25 ].…”

The article lays out the methodology for shaping the design features of a strain gauge transducer, which would make it possible to study forces and torques generated during the operation of symmetrical seeder coulters. The transducers that have been known up until now cannot be used to determine forces and torques for the coulter configuration adopted by the authors. For this purpose, the design of the transducer in the form of strain gauge beams was used to ensure the accumulated stress concentration. A detailed design was presented in the form of a 3D model, along with a transducer body manufactured on its basis, including the method for arranging the strain gauges thereon. Moreover, the article discusses the methodology of processing voltage signals obtained from component loads. Particular attention was paid to the methodology of determining the load capacity of the transducer structure, based on finite element method (FEM). This made it possible to choose a transducer geometry providing the expected measurement sensitivity and, at the same time, maintaining the best linearity of indications, insignificant coupling error, and a broad measurement range. The article also presents the characteristics of the transducer calibration process and a description of a special test stand designed for this purpose. The transducer developed within the scope of this work provides very high precision of load spectrum reads, thus enabling the performance of a detailed fatigue analysis of the tested designs. Additionally, the versatility it offers makes it easy to adapt to many existing test stands, which is a significant advantage because it eliminates the need to build new test stands.

“…(Nada, 2003;Elgwadi 2005) presented a direct method of estimating tractor power by measuring torque and numbers of revolutions of the tractor power take off shaft, during operating rotating agricultural implement at actual field work. Miszczak (2005) mentioned that there were many models describing the work of rotary tillers, including torque valuation because the torque requirement may be very important for designers, as well as for other experts applying such machines in the field operations. Strain gage load devices convert the load acting on them into electrical signals.…”

The tractor test systems were conducted to evaluate the effect of the modified system and compared to the system used in tractor test station on the value of tractor performance. The developed device is consisted of transducer, signal conditioner and recorded unit. The hydraulic pull dynamometer, strain gage pull dynamometer, load cell, hydraulic PTO dynamometer, magnetic pickup transducers and fifth wheel were used to measure tractor parameter. Statically analysis shows that no significant between devolved device (named system 1) and the system used in tractor test station (named system2). Devolved device is expected to be a worthy one to establish reliable data of the performance parameters of tractors and implements.
