In this thresher at the centre there is a round drum and at the regular interval there are triangular iron hooks. It is operated by pedal and paddy bundles withhold in hand and placed on a moving drum. There is more number of rotations of main drum gets increased due to gear reduction. Due to light in weight it is portable. This thresher has capacity of 300-600 kg. Per hour. This thresher can be operated on single phase, having 1 HP motor with 1440 RPM.

• Corn roller

In corn roller when cobs are placed in the roller, the grains become separated and busha can be removed with the help of fan and clean grains are collected. It requires 2 labours one for moving the wheel and another for placing the cobs in. With this thresher per hour 55-700 kg grains can be obtained. Also there is a hand operated cob sheller. Hand operated cob sheller is a iron pipe of 6.5 cm. diameter and having length of 6.5 cm. and inside there is corrugated iron belts are placed. When dried cob is placed inside the sheller grains get separated with the corrugated iron belts. At a time only one comb can be decorticated, it is useful for small-scale decorating of corncobs.
