Hungry, high-residue cultivators The 5630HR series of Krause flex-wing field cultivators, available in self-leveling and floating hitch models, can tackle high-residue situations. Available in three-section and five-section models, the cultivators feature positive mechanical depth control, adjusted with ratchet jacks on each section. This system eliminates unwanted depth-control changes due to cylinder leak-down. A depth gauge, located on the center section, is easily visible from the tractor cab. Floating hitch models feature a unique tongue cylinder that locks the hitch into a rigid position for transport, yet allows a full floating position when in the field. Two shank options are available: K-tine and new spring-cushion models. Sizes range from 27 1/2 to 50 1/2 ft. Prices start at $14,006. Contact Krause Corp., Dept.
