An improved raking device comprising extendable rake heads for raking granular material.

An agricultural row cleaner having: a frame; a first row cleaner wheel disposed on a first side of the frame; a second row cleaner wheel disposed on a second side of the frame; and a third wheel attached to the frame and having a leading edge disposed forward of the first row cleaner wheel and the second row cleaner wheel along a direction of travel.

A tillage implement includes a frame, a first sensor coupled to the frame and configured to measure an orientation of the frame, a shank engaged with the frame and carrying a tilling tool, and a second sensor coupled to the shank or the tilling tool and configured to measure an orientation of the tilling tool. A system for working a field includes a tillage implement and a tractor drawing the tillage implement. The tractor may include a computer configured to receive information from the first sensor and the second sensor and control an operating parameter of the tillage implement. Related methods and computer-readable media are also disclosed.

An implement for tilling the soil and methods of using the same. The implement may include cultivator sweeps arranged in staggered rows, trailing coulters positioned behind a rearmost row of the cultivator sweeps, and a finishing attachment positioned proximate the trailing coulters. The trailing coulters are designed to penetrate deeper into the soil than the cultivator sweeps. The method includes passing such an implement through the soil such that the trailing coulters pass through the soil after the sweeps and the finishing attachment passes over and/or through the soil.

A system for controlling an implement during a tillage operation may include a frame and a ground-engaging tool pivotally coupled to the frame and movable relative to the frame between a retracted position and an extended position. An actuator may be configured to bias the ground-engaging tool towards the extended position during the tillage operation. An adjustable valve may be configured to permit flow out of the actuator when a fluid pressure of the actuator exceeds a reset pressure such that the actuator allows the ground-engaging tool to pivot towards the retracted position. A controller may be configured to determine at least one of an actuator position or a load value indicative of a force applied by the ground-engaging tool against the soil during the tillage operation and adjust the reset pressure based on the at least one of the actuator position or the load value.

In one aspect, a system for monitoring the frame levelness of an agricultural implement include first and second sensors configured to capture data indicative of a position differential defined between a soil surface and a portion of an a first and second ground engaging tool positioned below the soil surface, respectively. The captured data may be associated at least partially with the receipt of sensor signals reflected off of the portion of the associated ground engaging tool positioned below the soil surface. The system may also include a controller configured to determine penetration depths of the first and second ground engaging tools based on the captured data received from the first and second sensors, respectively. The controller may also be configured to monitor the frame levelness based on a penetration depth differential defined between the first and second penetration depths.
