| Abstract | ||||
| The objective of this study was to determine the physical, mechanical properties and pods placement of two snap bean (Phaseolus vulgaris L) varieties Bronco and Contender which dominate bean production in Giza, Egypt. These properties were used to develop a snap bean stripping prototype. The average plant height was 43.79, 46.66 cm for 'Bronco' and 'Contender', respectively. pod characteristics were determined while pod placement shows that 56 %, 36.6% of pods on the top, 43 %, 54.5% of pods on the middle and 1 %, 8.9% of pods on bottom of the plant for Contender, Bronco respectively. The average pod detachment force was determined as: 6.57 and 12.68 Nfor 'Bronco' and 'Contender', respectively. The highest coefficient of static friction was obtained with a plastic surface in both varieties as 0.82 for 'Bronco' and 0.83 for 'Contender'. This was followed by steel and rubber surfaces. | ||||
