The Top Air Onion Rod Lifter Series utilizes the counter rotating square rod concept to undercut onions. The slightly inclined tandem rod design allows the first rod to make the initial cut, with the second rod loosening the soil from the roots for faster curing of the onions. After undercutting, the onions maintain their upright position to help avoid sunburn. The hydraulic drive replaces drivelines and gearboxes for extremely low maintenance. Guage wheels maintain precise depth for a close, consistent cut. Onion savers can be utilized to prevent onions from falling into corrugations or wheel tracks. Rod Lifters are custom manufactured to match any bed configuration. Our solidly designed Top Air onion harvesters are manufactured with integrity to give our customers years of low maintenance operation.

The Top Air Onion Digger Series of harvesters has become a popular solution to undercutting onions in the southern United States. As this area is subject to frequent rains during the harvest season, the onions are best undercut and placed on top of a firm bed. Top Air diggers accomplish this by first undercutting with a blade. Then, conveying the onions up a belted chain bed to remove soil from the roots, which allows for better curing. Then, firming the soil with a roller, which allows rain water to run off the bed. The onions are then laid back on to a firm bed. This method allows the soil free roots and tops to dry in these difficult climatic conditions.
