Field cultivators are heavy farm or agricultural machines that are meant for tilling soil. There are two primary types. One has shanks, or teeth, that poke holes in the soil while being dragged on their frame in a line through the field. The other kind spins its teeth, or disks, in a rotary motion to pierce and agitate the soil.
These machines are often used before planting in order to aerate the soil and prepare seed beds. They also mix the soil in order to incorporate appropriate nutrients throughout. Sometimes they’re employed after the crops are planted as a means of interrupting and destroying weed growth. This is able to work because cultivators disturb the soil in a very strategic and controlled manner, in which only the weeds are touched and the plant is left in place.
Cultivators can be self-propelled or pulled behind a tractor. Some may even be pulled by work animals such as horses. For industrial use, though, field cultivators are usually pulled by tractors. Row-crop tractors are the most commonly used for this purpose. Depending upon their intended use, these commercial-grade cultivators can be as narrow as 10 feet wide or as wide as 80 feet wide. Typically, the larger ones have hydraulic wings that are able to be folded for safety in travel. There are a few different ways to attach a field cultivator to a tractor. These include drawbar, three-point hitch or frame mounting. The depth of cultivation can be controlled through the use of hydraulic cylinders that raise and lower the frame.
