An removably installable apparatus and system for managing weight transfer along a tractor drawn tool bar for use in row planting systems is provided. The planter weight transfer system comprises first and second bolt-on bracket assemblies secured to each other and to a row planter tool bar by a set of fasteners. Additionally, the bolt-on brackets are joined at the top by an actuator which applies a force on the brackets.

A method for determining a mass of an implement includes providing a rear powerlift having at least one upper link and at least one lower link and a support structure disposed at the rear of a utility vehicle. The method includes defining an angle () between the upper link and a vehicle horizontal line, an angle () between the lower link and the vehicle horizontal line, an angle of inclination () of a vehicle horizontal line relative to a terrestrial horizontal line, a path (LV) representative of a connection along the lower link between the support structure and the implement, and a force (F.sub.U) impinging on a connection between the upper link and the implement and acting along the upper link. The mass is determined by at least one of the angle (), the angle (), the angle of inclination (), the path (LV), and the force (F.sub.U).

A subsoil tool for ameliorating soil compaction having a shank attached to a toolbar of a tractor, wings on forward wing links pivotally engaged to the shank, and following wings on a wing rod pivotally engaged with the forward wing link. The forward wing links are positioned near the bottom of the shank in front of the rear of the shank. The wing rod is positioned behind the shank. A power link is engaged to the toolbar, a hydraulic drive cylinder, and the wing rod for enabling oscillation of the wing rod relative to the shank.

An agricultural work system has an agricultural work machine to which at least one mounted implement can be fitted via at least one implement interface. A work machine configuration is associated with the work machine, and a mounted implement configuration is associated with the mounted implement. A drive unit is provided which acts via a drivetrain on ground engaging elements, particularly on tires. A system control and a control/display unit associated with the work machine are provided. It is proposed that the system control is adapted to determine the mounted implement configuration, to calculate the implement interface load transmitted via the implement interface based on the determined mounted implement configuration, and to evaluate and/or optimize the work machine configuration based on the calculated implement interface load.

Systems, methods and apparatus are provided for managing implement weight. In some embodiments, a position sensor is used to determine a position of the wing section and a downforce applied to the wing is modified in order to lower the wing section. In some embodiments, the position sensor indicates the position of a wing wheel assembly of the wing section. In other embodiments, the position sensor indicates the position of a center wheel assembly of a center section of the implement.
