A system for determining field surface conditions may include a frame member and a ground engaging tool coupled thereto. The ground engaging tool may be configured to engage soil within a field as an agricultural implement is moved across the field. The system may further include a vision sensor having a field of view directed towards a portion of a surface of the field and being configured to capture vision-based data indicative of a field surface condition of the field. The system may also include a secondary sensor coupled to the ground engaging tool and configured to capture secondary data indicative of the field surface condition. Additionally, the system may include a controller configured to determine an initial surface condition as a function of the vision-based data and to adjust the initial surface condition based at least in part on the secondary data received from the secondary sensor.

In one aspect, a system for de-plugging an agricultural implement may include an actuator coupled between a ground-engaging tool of the implement and a frame of the implement. The actuator maybe configured to move the ground-engaging tool relative to the frame between a first position in which the tool penetrates the soil and a second position in which the tool is lifted out of the soil. Furthermore, the system may include a sensor configured to capture data indicative of plugging of the ground-engaging tool. Additionally, a controller of the disclosed system may be configured to determine when the ground-engaging tool is plugged based on the data received from the sensor. Moreover, the controller may be further configured to control an operation of the actuator such that the ground-engaging tool is moved from the first position to the second position when it is determined that the tool is plugged.

A handheld gardening tool includes a power source, a spike projection device adapted to roughen soil for the application of grass seeds or to ease pulling weeds, and a support arm connecting the power source to the spike projection device. The spike projection device comprises a housing supporting a plurality of spikes mounted within the housing for controlled extension from and retraction within the housing for engagement with soil.

In the case of a soil cultivation device with multiple harrow tines, the harrow tines are fastened to levers, which are mounted to pivot on tie bars of the supporting frame via carriers. The operating position of the harrow tines is defined by the levers being adjacent to tie bars, and the harrow tines are prestressed into the operating position by springs assigned to them in the form of pneumatic cylinders.

A harrow has a frame, tines pivotal on the frame and each a lower arm with a soil surface under the harrow. An actuator on the frame can shift a bar frame shiftable horizontally on the frame. Respective spring biasing units above the axes each have a guide element connected to the bar frame and displaceable therewith through a predetermined displacement path, a connecting element connected to respective upper arms of the tines, a first compression spring bearing on both of the elements and biasing the other element away from the one element so as to press the lower arm downward into the soil surface during movement of the respective guide element through the path, and a second compression spring bearing continuously on one of the elements and engageable with the other of the elements after displacement of the respective spring-biasing unit only through a part of the path.

This present disclosure relates to an earthworking tine and method of manufacture. More particularly the disclosure is directed to a earthworking tine with a hardened end and related methods. Specifically, the disclosure relates to an earthworking tine with an indicator layer to indicate wear and potential tine failure before failure occurs.

A system for adjusting down pressure loads on a harrow of an agricultural implement may include a base hitch member and an upper tow arm pivotally coupled to the base hitch member. First and second linkage arms may pivotally couple to the upper tow arm. A lower support arm may pivotally couple to the first and second linkage arms. A plurality of ground engaging elements may be supported on the lower support arm. A tensioner assembly may include an actuator coupled between the base hitch member and the lower support arm. The actuator may include an actuator rod that extend and retract to adjust a relative distance between the base hitch member and the lower support arm. The actuator may regulate a down pressure applied on the plurality of ground engaging elements by adjusting the relative distance between the base hitch member and the lower support arm.
