In: Misr Journal of Agricultural Engineering 2002.v.19(1)Summary: The aims ofthis study are to investigate factors relevant to design of a 4-har feeding device, to accept a variety of seeds including: maize, wheat, sunflower, peas and cotton Study included: a computer progtam to draw the mechanism in different configuration. Machine speed; wheel slip; and construction of agitator were also studied. The main results can be summarized in the flowing points: -The appropriate 4-bar proportions are: 1.0, 1.5, 1.6, and 1.73 for crank, swing rod, con. rod. and base respectively. -The average forward walking speed was 3.5-4 km/h. -Hopper was found to need an agitator device, to regulate seeds distribution for big seeds like maize, sunflower and peas. -Metering device could be used in small grains, like wbeat wilhout agitator (with only 1.19 % missing spaces).
