An arrangement of electrodes for removing weeds by contact electrocution comprising: a general support (1) formed by a first connection means (2) associated with the proximal end of a deformable frame (3), and a first mounting means (5); a first electrode support (8) associated with said general support (1) by said first connection means (2); a second electrode support (22) associated with said general support (1) by the distal end (4) of said deformable frame (3); wherein said first electrode support (8) includes a first electrode (15); and wherein said second electrode support (22) includes at least one electrode (29).

An apparatus for tending to rows of vines is presented which may be pulled, or driven, between a pair of rows of a vineyard. The apparatus includes implements to tend to the vines on both rows at the same time. The apparatus include a left portion that tends to a left row of vines and right portion that tends to a right row of vines. The portions are attached to the apparatus using linkages that permit the portions to adjust to changes in row spacing or the position of the apparatus between the rows. The apparatus also includes weeder assemblies that weed the ground between the vines while preventing damage to the vines, and a spray device for spraying the vines.

A method for growing plants includes both a seeder and a harvester both of which include arrangements for singulating the seeds and for measuring parameters of the seeds while singulated. This can be used for seeding selected seeds and for harvesting particular plants. The system operates by correlating information from the individual seeded seeds and from the harvested seeds in respect of a particular location on the growth medium and may include information relating the growth medium at the location. The location can be determined by seeding the plants in patterns which can be detected by a reader on the harvester. The system can be used to control selection of seeds to take into account soil conditions at the plant.

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.

Steered caster wheel systems that include a disengagement system to enable a caster wheel steering mode and non-caster wheel steering mode are disclosed. In some embodiments, the caster wheels are mounted to a subframe that may be independently suspended from the chassis of a vehicle such as a self-propelled vehicle.
