Benefits of technology
Enhances seeding accuracy and reduces tool damage by allowing the packer wheel to clear obstacles while maintaining contact with the soil, improving crop yield and reducing maintenance costs.
Problems solved by technology
However, the appropriate spacing between the ground engaging tools and the packer wheels may be less than optimal for all situations.
For example, when the implement is being pulled more quickly through a field, a wheel that was properly spaced when moving more slowly may be too close.
On the contrary, if the wheel is spaced farther from the tool as might be appropriate for higher speeds, this distance may not be optimal for slower speeds.
Moreover, the ground engaging tools may encounter obstacles in the field, such as large clods or rocks.
The obstacles may deform, damage, and / or break the tools if the implement is traveling at a high speed and / or the obstacle is large.
Unfortunately, such configurations of the implement may sacrifice accuracy and control over the depth of soil valleys in order to avoid tool damage due to obstacles.

Embodiment Construction
[0012]Turning now to the drawings and referring first to FIG. 1, an embodiment of a precision hoe opener assembly is illustrated and designated generally by reference numeral 10. As may be appreciated, the precision hoe opener assembly 10 is a type of row unit, which may be placed on an agricultural implement, such as a planter or seeder. The precision hoe opener assembly 10 includes a frame support 12, a packer wheel assembly 14, an adjustment mechanism 16, a first member 18, a linear actuator, in the form of cylinder 20, and a second member 22. The cylinder 20 may be a hydraulic or pneumatic cylinder assembly and may be coupled to a power supply that is used to provide a flow of pressurized hydraulic fluid to displace as a rod extending from the cylinder. The precision hoe opener assembly 10 may be part of an implement assembly that is towed by a vehicle, such as a tractor. For example, the frame support 12 may couple to a tool frame tool bar connected to the tractor, via a hitch ...

An implement includes a frame configured to couple to a tool bar, a linkage coupled to the frame, and a ground engaging tool extending from a shank, wherein the shank is coupled to the linkage. The implement also includes a packer wheel configured to control a position of the ground engaging tool, wherein the packer wheel is positioned behind the ground engaging tool when the ground engaging tool is engaging the soil. Further, the implement includes an adjustment mechanism configured to allow for adjustment of the distance between the packer wheel and the ground engaging tool.
Description
BACKGROUND[0001]The present invention relates generally to the field of agricultural implements, such as tillers and implements towed behind a work vehicle, such as a tractor.[0002]A wide range of agricultural implements have been developed and are presently in use for tilling, cultivating, harvesting, seeding, and so forth. Seeding implements, for example, are towed behind tractors and open rows of soil for deposition of a seed or product in the soil. The implement may include a plurality of ground engaging tools. In certain implements, packing wheels may follow the ground engaging tools to close valleys and / or pack soil after seeds or fertilizer has been deposited into the valleys opened by the tools. In general, these wheels are spaced from the tools by a fixed distance, determined at the time of design and / or manufacturing of the implement. However, the appropriate spacing between the ground engaging tools and the packer wheels may be less than optimal for all situations. For ex...
