The high number of accidents due to rollovers of agricultural machines has increased the interest of researchers and organizations for standardization in this field. In the 1960s, standards to test rollover protective structures (ROPS) for tractors were designed and approved. Similar standards were introduced in the 1990s for earth-moving machinery, but ROPS standards were not defined for self-...

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 ...

Improved human-tractor interface designs, such as well-accommodated operator enclosures (i.e. cabs and protection frames) can enhance operator productivity, comfort and safety. This study investigated farm-worker anthropometry and determined the critical anthropometric measures and 3-D feature envelopes of body landmarks for the design of tractor operator enclosures. One hundred agriculture wor...

Introduction Direct energy expenses (diesel, gasoline, propane, electricity) total more than $1 billion annually for Iowa’s farmers. Day-to-day farm management techniques such as adjusting tractor gear and throttle settings or monitoring tractor tire inflation pressures can reduce diesel fuel consumption for row crop production. This study is being conducted over multiple years to measure the e...

The optimization of energy input on agricultural farms, such as through improved fuel consumption, is currently under investigation in mechanization research with the aim achieving economic and environmental goals. In previous research, we developed a simplified algorithm focused defining most efficient tractor–implement combination considering factors that influence this aspect. ASABE (America...

This paper presents experimental research evaluation of the vibration exposure for the health risk prediction during vehicle operation. The vibration measurements were carried out on a recreational vehicle and two types of agricultural tractors. The vibration levels were measured for different surfaces and vehicle speed conditions. Based on the analysis of the results in the small agricultural ...

This study is focused on the estimation of fuel consumption power-shift transmission (PST) tractor based PTO (power take-off) dynamometer test. The simulation model PST was developed using configurations and powertrain real tractor. installed to measure engine load at various levels (40, 50, 60, 70, 80, 90%), verify model. axle also predicted tractor’s specifications as an input parameter measu...

Increased productivity of machine-tractor units in the conditions agricultural production is one most important and urgent tasks engineering technical service sector. The greatest impact on machine reliability performance indicators has a timely good-quality maintenance. Fault tolerance crucial to ensuring high productivity. amount maintenance work increases proportion number hours worked. Inad...

This study focuses on reducing the fuel consumption and exhaust gas emission values of tractor used in agricultural field. With additive added to coating engine, were reduced, production costs tried be reduced. On other hand, also reduced thus a more environmentally friendly method was aimed adopted. For this reason, cylinders engine coated with Al2O3 + 13%TiO2 metal powders mixed by mass using...
