Objectives of this study were to develop a small-scale peanut pod stripper and to examine the quality of seeds obtained. The machines were developed and tested and the peanut seeds were analyzed in Ubon Ratchathani, Thailand, in 2000. Two types of pod stripper were constructed. One machine had rubber bands with a zigzag rim type and the other machine had iron rods sheathed with a water hose type. Each machine was attached in front of a two-wheeled tractor and was run by the tractors engine. Tainan 9 and SK38 peanuts, 110 days old, were tested with these two pod strippers and were compared with peanuts stripped manually. Harvested peanut pods were put in open storage at different periods of time, then the seeds were tested for germination, tetrazolium staining and electrical conductivity. Test results showed that both pod strippers yielded about 80 percent of good pods without pod stalks, 9 percent of good pods with pod stalks, 4 percent of split pods and the remaining 7 percent were young pods. Pod quality, in terms of external appearance, was not up to the standard because of pod stalks, but might be acceptable for boiled peanuts. For the seed tests, in general, the quality of peanut seeds obtained from both pod strippers was slightly lower than seeds stripped by the manual method. However, the quality of seeds obtained from the rubber bands type pod stripper, in many cases, was not significantly different from that of the manual method. This showed that this particular pod stripper had a potential for further improvement.
