A method for autonomously performing an agricultural operation includes automatically moving a vehicle having at least one agricultural operation device to a starting location for the agricultural operation. An indicator for the starting location is optically identified. A position of the vehicle to a selected distance from the indicator is automatically adjusted. The agricultural operation device is automatically operated. The vehicle is automatically moved along a selected trajectory and the automatically operating the at least one agricultural operation device is repeated until a predetermined number of automatic operations of the agricultural operation device have been performed.

A tractor mounted tiller/cultivator system that includes right and left swing arms pivotally attached to tractor chassis, right and left cutting head assemblies mounted on the swing arms, each including a right disc motor driving a rotary disc mounted on a distal portion of the swing arm and operatively coupled to the motor. Ground-engaging cultivation wheels surround the rotary disc, and an annular guard prevents unwanted contact of the wheels with vines or trunks of vines and trees. A drive mechanism lowers and raises the swing arms to put the cultivation wheels into engagement and disengagement with ground and to rotate said swing arms about their longitudinal axes. User controls operatively connected to the swing arms, cutting head assemblies, and drive mechanisms enable a user to finely tune the movement of the cutting heads into and out from rows of trees or vines.

Systems and methods relating to the replacement of specific parts in farm equipment to thereby adjust the farm equipment's capabilities. To modify the ground clearance of farm equipment, especially sprayers with a strut type suspension, the spindles of the suspension system along with the air spring absorber are replaced. The original spindles are replaced with longer spindles while the air spring absorber is replaced with one that allows for an increased range of travel. As well, the fixed linkage arms that connect the air height control valves to the suspension system are also replaced with longer arms. These longer linkage arms may be of a fixed length or they may be of an adjustable length.

An agricultural machine for arrangement on a vehicle, wherein during movement of the machine in the travel direction an area of soil at least between plants arranged parallel to the travel direction in row crops can be tilled by the machine, wherein the machine comprises a soil tillage tool, which is pivotable back, counter to the travel direction, about an axis of rotation running in a height direction of the machine out of a transverse direction arranged perpendicular to the travel direction and perpendicular to the height direction and/or is movable towards the machine in the transverse direction, an obstacle sensor by which obstacles can be detected, and comprises a control device, wherein when an obstacle is detected the control device can pivot the soil tillage tool back out of the transverse direction counter to the travel direction and/or move it in the transverse direction towards the machine.
