Considering the low skill and low per capital income of majority of developing countrie's farmers, an alternative equipment to replace manual harvesting of grains like rice and wheat must not be made sophisticated but cheap enough to operate and own. Stripper header's technology is simple and can be produced as small as possible to maneuver on the small parcel field and can be made big enough to replace conventional combine harvester's head for large farmland. The grain stripper detaches grains from the stalk head at high speed with insignificant mechanical damage to the grains and conveyed the strripped materials well into the harvester's grain tank from where it is discharged for final cleaning.
