When sowing grain we apply resource saving technologies-technologies such as «no till» and a technology called «mini-till». «No till» involves planting crops on untreated surfaces. "Mini-till" is designed for the planting with minimum tillage. During the movement of the sowing unit on these agricultural backgrounds we can see working bodies tipping out. Stabilization of the drilling depth is ensured in two ways - by moving part of the weight of the planter on the opener or the installation of ballast weights. Openers of grain drills for resource saving technologies for grain crops can be divided into three groups – foot, disc and anchor. Disc coulter has varieties – single disc, double disc and montesquiu coulter. To analyze the cost of power for the operation of the opener, the following indicators – the minimum engine power of the tractor on the coulter and engine power of tractors per unit of working width. The calculation of the indicators was conducted using data the technical specifications of the planter. Snow coulter drill AGRATOR4800 provides a wide spread planting strip of 10-15cm. The minimum power of the engine of the tractor on the opener is 7.5 HP minimum power of tractor engine per unit of working width 25 HP/m. Double disc opener planter Great Plains has a minimum engine power of the tractor on the opener 2.7 HP and per unit of working width 26.0-28.44 HP/m. Planter equipped with disc knife for strip tillage. The planter Condor 1201 is provided with a chisel opener «ConTeC». The engine power of the tractor on the opener of the planter is 4.58 HP, the engine power of the tractor unit working width constitute l8.33 HP/m. This grain seeder has reduced power losses and provides sowing with a «no till» technology
