Results of experimental studies of the plow for coupling with drawbar category 3 tractors

BACKGROUND: For the cultivation of agricultural crops, technology basic dump tillage is widely used. More than 40% energy resources are spent on it, due to traction resistance working bodies general-purpose plows. The technological process plowing with such has not changed much historically. Pruning soil layer carried out a ploughshare, crumbling and turning blade, stability movement body provided by landside plate. At same time, plate accounts for up 20% total component plow body. To reduce resistance, without been developed in Saratov State Agrarian University.
 AIMS: Determination towing operational characteristics PBS-5M ploughshare coupling drawbar category 3 tractors operation heavy loamy soils.
 METHODS: experiments were field, cultivated disk harrow after winter barley harvesting, Novokubansky district Krasnodar Region. 030 cm had moisture ranged from 16.4 19.7% hardness 1.86 2.74 MPa. mass plant crop residues site averaged 185 g/m2, average height weed plants was 10.8 cm.
 RESULTS: unit, consisting serial T-150K tractor an experimental plow, have determined. two variants plow. first variant five-body configuration grip width 2.83 m depth 22 cm. second four-body 2.27 30 driving mode T-150K+PBS-5M unit varied operating velocity range 7.27 9.2 km/h, 5.72 km/h. intensity determined, corresponding power small reserve 2.87%. requires power, almost equal engine.
 CONCLUSIONS: As result studies when processing it found that can be coupled 3. reasonable at 78 km/h 2122 output during main time 2.12.3 ha/h, fuel consumption 12.912.7 kg/ha. specific 47.546.78 kWh/ha, 31.2631.4 kWh/ha. engine load track skidding 6.99.7% 7886%. With increasing depth, values raise as well. In field studies, necessary use higher order couple 10 these agrotechnical conditions.
