The conservation tillage model has been widely promoted throughout the country. As an important part of it, no-tillage sowing is particularly important.

In China's agricultural machinery subsidy system, the two-row traction no-tillage precision seeder made in Heilongjiang, which has the highest local sales volume, is Bojin Hummer 2BMZ-2 and Debon Dawei 2BMG-2. Here, compare the detailed configuration and price of these two models for your evaluation and reference.

The matching power range of these two models is 22.1 ~ 40.5 kW for Hummer, which is 26 ~ 37 kW, which shows that there is no obvious difference in power demand. The hourly productivity of Hummer is 0.5 ~ 0.7 hectares/hour, which is 0.6 ~ 1.1 hectares/hour. It can be seen that Dawei's efficiency is "higher".

Looking at the volume of the seed box, Hummer is 10 liters ×2, which is 35 liters ×2. The conventional fat box has a volume of 200 liters for Hummer, which is 270 liters. The volume of the mouth fat box is 6 liters ×2 for Hummer, which is 23 liters ×2. It can be seen that Dawei's seed box, conventional fertilizer box and mouth fertilizer box all have "more" volumes. Presumably, Dawei's single working time is "longer".

Bojin Hummer 2BMZ-2 No-tillage Precision Seeder

Looking directly at the overall dimensions (length× width× height), Hummer is 3000× 2050× 1500mm, which is 3100× 1880× 1570mm. Relatively speaking, Hummer is "shorter" by 10 cm, "wider" by 17 cm and "shorter" by 7 cm. It can be seen that there is no obvious difference between Hummer and Dawei in body size.

Look at the row spacing, which is 650 mm, but Hummer is suitable for 600 ~ 700 mm, and Dawei is suitable for 420 ~ 700 mm. It can be seen that the range of row spacing is "wider". The working width is also 1300 mm, but Hummer is suitable for 1200 ~ 1400 mm, and it is very suitable for 840 ~ 1400 mm. It can be seen that the working width is "wider".

還有，排肥器的數量，悍馬2，是3(肥，備用1) +2(口肥)。排肥車的驅動方式，悍馬采用地輪驅動+鏈傳動；大偉采用地輪驅動+上壓輪鏈傳動，口肥采用電機驅動。

看播種排量的調節方式，悍馬采用變速箱+換鏈輪(換傳動比)，大幅度采用換鏈輪(換傳動比)。關于施肥出料的調節方式，悍馬采用變速箱+換鏈輪(換傳動比+手柄調節外槽輪工作長度)，大幅度采用換鏈輪(換傳動比+換槽輪工作長度)。

另外開溝(肥)式，悍馬用雙盤，大量使用單盤。開溝機(種)深度調節范圍悍馬為0 ~ 60mm，悍馬為30 ~ 80mm。悍馬開溝器(施肥器)的深度調節范圍為0 ~ 100毫米，最大可達60 ~ 130毫米?？梢姶髠サ拈_溝機(播種施肥)深度調節“更深”。

看地輪直徑，悍馬是630 mm，是711 mm，說明地輪直徑“大”了8.1 cm。悍馬的地輪高度調節范圍為0 ~ 150 mm，悍馬為0 ~ 200 mm?？梢钥吹降剌喌母叨日{節范圍“高”了5 cm。
