Abstract EN

The present study was carried out in Agriculture mechanization department , college of agriculture, university of Basrah to determine the draft force and power draft requirements the fuel consumption and specific fuel consumption of seed hill –drop and fertilizer .

The planter was designed and manufactured in the workshops dept.

The planter width was 2.1m and provided with three Suffolk coulters.

The planter drawn by Antor 80 .

The experiments was tested using four forward speed 0.48 , 0.76 , 1.20 and 1.68 m/sec , three coulters 2.5 , 5 and 7.5 cm.The experiments were unducted at engine speed of 1500 RPM .

The results showed that increasing the forward speed increase the draft force, and power and fuel consumption.

The maximum value of draft force, and power requirement and fuel consumption are 0.97 kN , 1.63 kW and 5.88 kg/h respectively for a depth 7.5 cm .

While the minimum value of draft force,and power requirements and the fuel consumption is 0.86 kN , 0.41kW and 3.44 kg/h respectively at depth 2.5 cm .

Also, the study showed that increasing forward speed on the upper factors has more effect than that of coulter.

The specific fuel consumption for the planter increased with both the forward speed and the coulters depth .It increased from 1.53to 5.40 kg/kW.h when the forward speed and the coulters depth increased from 0.48 m/sec and 2.5 cm to 1.68 m/sec and 7.5 cm .

The specific fuel consumption for the coulter and the rolling resistance of the tires also increased with both the forward speeds and the coulters depth.
