A mechanical harvester for harvesting, topping and sacking bulb crops, such as onions. The harvester extracts the onions from the ground and transports them rearward to a cutting assembly by conveyor systems that drop out small onions, dirt, rocks and debris. The cutting assembly comprises a set of elongated cutting blades positioned to cooperatively accept and sever the leaves and roots from the bulb. The offal drops away from the harvester to the ground by manner of gravity. After cutting, the onions are transported through an inspection assembly for inspection, sorting, grading and further distribution. The onions are then transported rearward to a sacking assembly for placing the onions into sacks, to a chute device returning the onions to the ground or to a conveyor system transferring the onions to an adjacent vehicle. Platforms on the sides and ends of the harvester facilitate the above operations.
