Abstract:
Abstract The paper is focused on the issues of controllability of machine-tractor units based on wheel-type tractors during their non-straight driving on the soil surface, which is positioned at an angle to the horizon. There were obtained analytical expressions for the determination of the actual indicator of control λd, including both the power and the design parameters of the machine-tractor unit, which affect the abovementioned indicator in the longitudinal vertical plane. These expressions are obtained for the tractor driving on both road and also driving during field operation. In additi

One of the main indicators of internal combustion engines, tractors and the machine-tractor unit as a whole it's the power. It can change in the process of operation and there comes a time when subsequent use is inadmissible or inexpedient. In such a state, it is appropriate to apply technology to improve this indicator and reduce the fuel or lubricant consumption. The power parameter of an agricultural power machine is essential to achieve high productivity with low operating costs with minimal environmental pollution.

Abstract Modern sowing machine-tractor units (MTU) can be divided into single-machine (single-module), two-machine (double-module), and three-machine (triple-module). The firsts, consisting of a tractor and a trailed/mounted seeder, are the most studied and, therefore, the most widespread. Two-module MTUs mainly use trailed or semi-mounted hitch and trailed seeders. The units of this type have been studied less. Three-module sowing complexes are even less common. Most are based on a trailed hitch and trailed seeders placed behind the tractor. There are samples of MTU with side-mounted seeding

As a result, an asymmetric unit was obtained, in which the cultivator is displaced in the transverse direction relative to the tractor symmetry axis by half the inter-row width, equal to 70 cm.

The efficiency of the machine-tractor unit depends on the operational energy saturation of the tractor, which is determined by the optimal ratio of the engine's operating power to the tractor's operating weight. The operational energy saturation depends on the operation performed. Conditional energy saturation is a constant indicator equal to the ratio of the rated power of the tractor to its operating weight. The article describes a method for calculating the traction characteristics of a wheeled tractor with an energy saturation of more than 23 W/kg.
