Bed lifters - or undercutters - span a bed of garlic or onions to fracture and heave soil for easy crop harvest. Use for other vegetable crops, including carrots or sweet potatoes. Sufficient power to pull generally ranges from 35 to 60 HP.

​

Gauge wheels are ideal but usually not essential. Coulters can be added to customize, possibly for removal of plastic mulch. Bed lifter blades can be mounted to bed shaper or cultivator toolbars.
