Abstract: A wear component for a ground engaging tool includes a mounting portion having a first surface, a second surface, and a thickness between the first surface and the second surface. The mounting portion is connectable to a mounting assembly of the ground engaging tool. The wear component also includes at least one wear portion connected to the mounting portion and forming at least one ground engaging edge. The at least one wear portion has at least one first surface including at least one groove extending from the at least one ground engaging edge toward the mounting portion, at least one second surface, and at least one thickness between the at least one first surface and the at least one second surface. A maximum of the at least one thickness of the at least one wear portion is larger than a maximum of the thickness of the mounting portion.

Abstract: In order to avoid cavitation in a boom cylinder head end at the beginning of a dig cycle, fluid from an alternate source is supplied to the head end before or in addition to fluid supplied by the main boom-up hydraulic circuit. In one embodiment, an electronic hydraulic valve, related sensors, and control system determines the beginning of a dig operation and uses fluid at an intermediate pressure to rapidly provide fluid to a boom head end cylinder to prevent voiding or cavitation before fluid under high pressure from the main pump can be brought to the cylinder. An on/off fluid switch is activated early in a dig operation to address low pressure at the boom cylinder head end and provide an alternate path for fluid into the cylinder in reaction to the boom being lifted by a motion of the stick and bucket in contact with the work surface.

Abstract: A wear component for a ground engaging tool includes a longitudinally-extending mounting portion connectable to a mounting assembly of the ground engaging tool. The wear component also includes at least one wear portion connected to the mounting portion. The at least one wear portion forms at least one ground engaging edge. The wear component further includes a plurality of longitudinally-spaced ribs projecting from the at least one wear portion and connecting to the mounting portion. The plurality of ribs are configured to affect a direction of a flow of material passing along the at least one wear portion.
