A standard fertilizer applicator with coulters and shank assemblies with knives for placement of fertilizer below the soil surface is equipped with cultivator shank assemblies for tillage between the fertilizer shanks. Each cultivator shank is mounted by a plate having notches therein for adjusting the vertical height of the assembly. The plate is attached to a support bracket placed around a square beam or tool bar. When used for spring application, leveling of uneven soil is accomplished and weeds are eliminated with the same pass made to apply the fertilizer.

A row-crop tractor including a tractor frame structure having a front portion and a rear portion. Two front wheels are rotatable mounted to the front portion of the tractor frame structure. At least a rear wheel is mounted to the rear portion of the tractor frame structure. A drive mechanism is mounted to the front portion of the tractor frame structure and connected to the two front wheels for controllably driving the same in dependence upon a control signal received from an operator of the row-crop tractor such that one front wheel is driven independent from the other. A front farm implement connecting mechanism is disposed at a front end of the front portion of the tractor frame structure and an operator seat mounted to the front portion of the tractor frame structure in close proximity to the front end of the front portion of the tractor frame structure such that the operator of the row-crop tractor is enabled to reach a front farm implement connected to the front farm implement connecting mechanism.

The invention relates to an adjusting device, which includes a lifting device for adjusting a position of an attachment in use and a locking mechanism. The lifting device is switched between a locking position and a free position under a locking action of the locking mechanism, the lifting device drives the attachment to move to a first position when the lifting device is in the locking position; and the lifting device drives the attachment to move to a second position so as to work when the lifting device is in the free position. The adjusting device of the present invention has a simple structure, a low production cost, an easy maintenance, and a garden tool using the adjusting device can conveniently and quickly adjust the position of the attachment connected to the garden tool.

Agricultural devices, row unit adjustment systems, and methods of adjusting a depth of a furrow. In some aspects, an agricultural device is adapted to plant seeds and includes a frame, a furrow opener coupled to the frame and adapted to cut a furrow including a depth, a sensor adapted to sense a characteristic associated with planting seeds and generate a signal associated with the sensed characteristic, and a processing unit receiving the signal associated with the sensed characteristic. The depth of the furrow is adjustable based on the signal associated with the sensed characteristic. Such characteristic may be a characteristic of the soil, a force applied to the agricultural device, or a position of a portion of the agricultural device.

A system for measuring soil electrical conductivity having a support, a plurality of soil engaging contacts (e.g. coulters) mounted to the support, at least one probe, and a processor. Current is provided through the soil and then measured. The voltages measured between respective opposed pairs of contacts are used to calculate the soil electrical conductivity of the soil within first, second, and third depth ranges. Each probe is selectively inserted within the soil and is configured to determine the soil electrical conductivity of the soil within the first, second, and third depth ranges. The processor correlates the calculated soil electrical conductivity of the soil within the first, second, and third depth ranges with the soil electrical conductivity determinations of the probe. Methods of determining and imaging soil characteristics and applying those characteristics to a crop model are included.

There is four major part of this invention, the name vehicle represent train, air plane, bike, bicycle, and wheel cart attachment unit. Again the invention have two vehicle types, the farm assembled vehicle is one and personal assembled vehicle is 2, the patent also describe the third major part of the invention as the assembled farm hoe technology, the invention also discussed the assemble of arm or arms technology. Lastly the invention discussed and illustrated the use renewable energy technology

The major parts mention seek to improve food productions with applied technology, improve speed of food production using mobile vehicle, apply the power of metal aluminum, rubber, plastic, etc.

The result is a better farm hoes technology, a better arm or arms technology, a better farm vehicles, a better personal vehicles. The technology promote autonomous farming, autonomous hoes, autonomous arm, or arms and autonomous personal vehicle.

The whole system use clean renewable energy, the clean energy make the vehicle affordable to the farmers, and make food affordable to consumers. Promote commerce.
