In: Misr Journal of Agricultural Engineering 2012.v.29(2)Summary: The aim of this research is to study some factors affecting the hole digger performance in the sandy soil. The experiments were conducted in ElKasasin Research Station in El-Sharkia Governorate. Auger diameters (250 mm) of the developed hole-digger were tested at different augerspeeds (75,100 and 150 rpm), auger pitches (10, 15 and 20 cm), hole depths (20, 30 and 40 cm), hole-spacing (5 m) and soil type (sandy) with moisture contents of 15,22 and 32 %. The obtained results can be summarized as follow: The maximum hole productivity rate for sandy soil was 335 hole/h obtalned with auger speed of150 rpm, hole depth 20 cm, auger pitch 20 cm at moisture content 32 %. The penetration resistance of sandy soil at 15 %moisture content increased by 30 and 40.6 %as compared with of sandy soil at moisture content 22 % and 32 %. respectively. The maximum fuel consumption was 0.59 L/h was obtained with auger speed of 150 rpm, hole depth 40 cm, and auger pitch 10 cm.
