*2.2.3 Motorized maize shellers*

This method uses the same concept as hand-operated maize shellers except that the shellers are powered using a motor or an engine (**Figure 4**). The shellers under this method can be categorized into immobile and mobile maize shellers [10]. These shellers save time and they reduce on the drudgery during maize shelling. However, the challenges with some of these shellers is that they are heavy [8], do not clean the maize kernels and are characterized with a broken percentage of 8.4 [1] which is *Improving Maize Shelling Operation Using Motorized Mobile Shellers… DOI: http://dx.doi.org/10.5772/intechopen.101039*

above the recommended 2% [20]. Motorized maize shellers use mechanically generated power to shell the maize. To facilitate speedy shelling of maize in large scale maize production, motorized maize shellers are recommended compared to hand-operated maize sheller [2]. The output of motorized maize shellers range between 500 and 2000 kg/hour and they can be operated by tractor power take off (PTO) or engines with power varying from 5 to 15 hp depending on the equipment used [2].
