تأثير سرعة الحراثة و زاوية الحرث و ميل القرص في انزلاق عجلات الجرار الزراعي وفي عمق الحراثة عند استخدام المحراث القرصي

Abstract EN

This experiment was conducted at the Agricultural Research Station, Mu’tah University in 2007, where the soil is a sandy clay loam (56% sand, 15% silt, 29% clay) to study the effect of three plowing speeds (4, 7 and 10km/h), three disk angles (35°, 45° and 55°) and three tilt angles (15°, 20° and 25°) on tractor wheel slip and plowing depth using mounted disk plow.

The plowing depth was adjusted at 20 cm.

The results showed that increasing the plowing speed significantly (p<0.05) increased tractor wheel slip and plowing depth.

Increasing disk angle of the plow significantly increased tractor wheel slip, while the effect of disk angle on plowing depth was not significant.

Increasing tilt angle of the plow significantly increased the tractor wheel slip and significantly decreased the plowing depth.

Results showed that 3.9% was the optimal wheel slippage, which was obtained from the combined effect of 4 km/h plowing speed, 35° disk angle and 15° tilt angle.

Moreover, results showed that 23.6 cm was the optimal plowing depth, which was obtained from the combined effect of 55° disk angle and 15° tilt angle.
