A removable motor housing for a plant material trimming device. The removable housing may include a first motor housing connectable to the plant trimming device. The first motor housing may be slidably or pivotably connectable to the plant trimming device. The first motor housing may be operable to receive an output shaft from a first motor in the first housing. The output shaft may be operable to communicate with an input shaft of the plant trimming device. A biasing device may be connectable to the first motor housing and the plant trimming device for biasing the first motor housing into a first position. When the first motor housing is in the first position a substantially constant force is applied between the input shaft of the plant trimming device and the output shaft of the first motor.
