Abstract
Three reliable devices have been developed and equipped with a developed ridger blade for controlling soil inverse angle, the blade lilt angle ,and the blade repose angle This developed machinery consl1\Jction Is able for establishing different ridge profiles suitable for different root crop growing conditions.
The developed ridger was Inspected and evaluated under three different deformation speed (s) levels, three levels, of angle (4)), three levels, of angle (a) and two levels, of repose angle (y). The performance of the developed furrower has been evaluated within detenninlng three main parameters namely: the swemng coeffICient of the slipped soil (A), the ridge profile deformation uniformity (PU) , and the specific draft for deforming the ridge (SO). In addition ridging performance of the developed furrower was compared with the ridging performance of the traditional furrower.
The gained results could be summarized as follows:-
1· The reliable swelling coefficient of the slipped soil (A =1.15) was corresponding deformation speed (s) of 1. 14m/sec, inverse angle (4)=45·), and tilt angle (a=20') at cutting width of aicm.
2· The maximum ridge height uniformity(PUn=94%} and the maximum ridge cross- section area uniformity (PU .•. =98%) , were accomplished forward speed of 1.45 rrvsec, angle (a) of 20 0 ,and angle (cP) between OD .and 22.50•
3- Traction force requirements of about 4.22 KN, was recorded as the developed furrower operated at forward speed of 1.76 m/sec deformation depth of 9.5 cm .versus traction force of 5.1 KN for the traditional ridger at the same operating conditions of zero inverse angle .. As the developed furrower was setting at Inverse angle of 45· the decrement rate in traction force was aboul 32% in favor of developed furrowsr compared to the traditional furrower
