Innovative local water evaporating air cooler intended for tractor cabs
Abstract
Design of innovative water evaporating air cooler intended for normalization of tractor-driver’s thermal condition by means of local airflow supply is proposed. The apparatus can be used both on new tractor models and on models under service, where air coolers are absent.

Evaluation of the impact of wheel tractor velocity and other factors on its oscillations
Abstract
Vertical oscillations of tractor Т-150К during operation on sandy soddy-podzolic soil prepared to sowing were investigated. As result of calculations carried out using experimental data on viscoelastic soil properties, the influence of a tractor velocity on appearance of mutually independent oscillations of its axes was shown.

Slipping work of speed synchronizer taking into account the influence of drive torque from declutched frictional clutches in a gear box
Abstract
Gear shift process by using a speed synchronizer in car and tractor gear boxes has been considered. The calculation method of slipping work and synchronization time for loading conditions of speed synchronizer, taking into account active drive torque from declutched frictional clutch, are proposed.

Improvement of a stubble ploughshare
Abstract
The task of perfection is to diminish load on the tractor and decrease cultivation blade wear, which will result in cost reduction of operation and repair of the aggregate. The technical result shows that share tractive resistance is diminished due to change in design.

Wear investigations of working parts of machines and technological equipment
Abstract
Wear pattern on the working surfaces of concrete mixer blades can be explained mainly by change of mix pressure on different points of working edge. The rotating blade angled to the rotation plane moves the mix both to direction of moving and along the concrete mixer axe. When high abrasive mixes of different fraction composition are prepared, wear of the working surfaces on thickness results in deflection, deformation and destruction of the blade.

Results of the exhibition Agritechnica-2013
Abstract
В Ганновере (Германия) с 10 по 16 ноября 2013 г. проводилась крупнейшая международная выставка сельхозтехники Agritechnica-2013. Организатор выставки, Немецкое сельскохозяйственное общество DLG, отмечает успех посещаемости: в 2013 г. в выставке приняло участие около 2900 экспонентов, в том числе рекордное количество иностранных – более 1500 из 47 стран. Численность участников на 7% превысила показатель предыдущей выставки (также почти на 11%, до 42 га, увеличилась выставочная площадь). Данный результат подчеркивает огромный интерес со стороны сельхозпроизводителей, подрядных предприятий и организаций по продаже сельхозтехники.
