An EMF detecting safety shovel has electromagnetic field (EMF) detection circuitry operably coupled to a blade thereof for measuring changes in EMF over time (AC fields) which may be used by spotters during excavation work for detection of subsurface power supply cables. The safety shovel may be further configured for classifying different types of subsurface power cables wherein the EMF detector circuit may be configured for discriminating between low and high voltage subsurface power cables when the edge of the blade is within a certain distance thereof, and the EMF detector circuit may be adjusted to adjust the distance for use with differing conduit diameters. The EMF detector circuit may also employ bandpass filtering to discriminate between single and three phase power supplies. In this way, the present safety shovel may provide indication of the presence of subsurface power supply cables and also the type thereof.

A micro-tiller module that is releasibly engageable with a hand drill can include a gear box assembly, first and second tilling wheel assemblies, and a stabilizer fork. The gear box assembly can include a housing, an input shaft extending along an input shaft axis, first and second output shafts, and a plurality of gears. The external end of the input shaft is configured to be releasibly engageable with a chuck of the hand drill. The tilling wheel assemblies can be respectively mounted to the output shafts. The stabilizer fork can extend from a base end fixed to the housing, along a stabilizer axis transverse to the input shaft axis, to a distal end from which first and second tines project. Each of the tines can extend further along the input shaft axis than transverse to the input shaft axis.

A detection system detects malfunctions in an autonomous farming vehicle during an autonomous routine using one or more models and data from sensors coupled to the autonomous farming vehicle. The models may include machine-learned models trained on the sensor data and configured to identify objects indicative of an operational or malfunctioning component within a tilling assembly such as a tilling shank or sweep. Additionally, a machine-learned model may be trained on sensor data to detect whether debris has plugged the tilling assembly of the autonomous farming vehicle. In response to detecting a malfunction or a plug, the detection system may modify the autonomous routine (e.g., pausing operation) or provide information for the malfunction to be addressed (e.g., the likely location of a malfunctioning sweep that has detached from the tilling assembly).

A work vehicle includes a frame and a row unit that is attached to the frame. The row unit includes a gauge wheel and a ground engaging implement. The gauge wheel is configured to ride on the ground surface and maintain the ground engaging implement at a predetermined vertical position with respect to the ground surface. Furthermore, the work vehicle includes a ground support unit that supports the frame for movement across the ground surface. The ground support unit includes an outer face. The outer face includes a non-treaded side area that defines a lateral side of the outer face. The outer face includes a tread area that is spaced laterally from the lateral edge. The tread area includes a plurality of projections. The non-treaded side area is aligned along the travel direction with respect to the gauge wheel.

An automated farming system includes a frame. The frame includes a fixed base, a beam, and a support. A farming implement support extends from the beam and moves up and down in relation to the beam. The farming implement support moves along a length of the beam. The movable support includes a propulsion system and is configured to rotate around the fixed base. Movement of the farming implement support and the movable support allows for high density planting of crops in hexagonal patterns and/or a continuous spiral pattern.

A mobile soil cultivation appliance includes a chassis with at least one drive axle for driving a travel movement of the soil cultivation appliance over the soil, a drive unit with a drive shaft, a work implement which is configured to be ascended and descended relative to the chassis and includes a drive shaft and at least one soil working tool which is movable for soil working upon rotation of the drive shaft. The drive shaft is connected to the output shaft by means of a power transmission means to allow the drive shaft to be driven by the drive unit, and the drive unit is connected to the work implement as a counterweight for the work implement in such a way that the drive unit descends when the work implement is ascended and ascends when the work implement is descended.

In one aspect, a system for detecting ground engaging tool float for an agricultural implement may include an implement having a ground engaging tool pivotally coupled to a frame and a biasing element coupled between the frame and the ground engaging tool. The biasing element may be configured to bias the ground engaging tool to a predetermined ground engaging tool position relative to the frame. The system may also include a sensor configured to detect a parameter indicative of a current position of the ground engaging tool relative to the frame. Additionally, the system may include a controller configured to monitor the current position of the ground engaging tool based on measurement signals received from the sensor and identify a time period across which the ground engaging tool is displaced from the predetermined ground engaging tool position. The controller may be further configured to compare the identified time period to a threshold time period to determine when a ground engaging tool float event is occurring during operation of the implement.
