Field cultivators, in various forms, have been in use since the earliest days of farming. They provide a way to break up soil, work crop residue into the soil, control weeds, and otherwise prepare a seedbed for planting. Early field cultivators were pulled by humans or animals such as horses or mules before the invention of tractors, which pull field cultivators using either via three-point hitch or drawbar. Field cultivators commonly have a series of shanks or shovels mounted on a frame that break up and move the soil, with some form of harrow or device with tines on the back to rake or otherwise smooth the soil surface.
Allis-Chalmers, Case IH, Glencoe, Great Plains, Horsch, John Deere, Kongskilde, Krause, Landoll, Sunflower, Unverferth, and Wil-Rich are among the leading manufacturers offering field cultivators. New and used field cultivators for sale come in a range of working widths (up to 18 metres or more; some with hydraulic wings for more easily transporting the cultivator), allowing farmers to best match their acreage needs and horsepower requirements.
Manufacturers are working to improve field cultivators. Recent Landoll 9600 Series cultivators, for example, have precision, laser-cut structural steel frames that are robotically welded for strength, while Landoll and several other manufacturers, including John Deere, are working on better “split-the-middle” shank spacing designs for more consistent depths and improved field coverage. Many field cultivators, including the newest Case IH Tiger-Mate field cultivators for sale, come with a choice of finishing tools, including spike-tooth or tine harrows and round bar crumblers.
