摘要： A carriage for a scarifier system of a machine includes a body portion having a leading edge, a trailing edge, and a first height. The body portion includes a first surface and a second surface spaced apart from the first surface, such that the first height of the body portion is defined between the first surface and the second surface. The body portion further includes a first side surface connecting the first surface and the leading edge. The body portion includes a second side surface connecting the second surface and the leading edge. At least one of the first side surface and the second side surface includes a beveled profile. The carriage also includes a plurality of shank attachment portions fixedly coupled to the body portion. Each shank attachment portion extends from the second surface of the body portion. Each shank attachment portion defines a second height.

摘要： Provided is an arrangement that attaches a ground-engaging tool (GET) to an adapter on support structure of ground/earth engaging/conditioning apparatus. A retainer is in a recess of the adapter. A fastener is received through the GET aperture and into the adapter aperture. The head of the fastener can be within a recess of the GET. The recess can be multi lobed/shaped to receive the retainer and prevent rotation or other torsional/lateral deformation of the retainer when tightening/inserting the fastener. A fastener has a first threaded portion adjacent the head of the fastener and a second threaded portion along a shaft portion of the fastener extending distal from the head. The first threaded portion can be wider and/or of a more coarse thread pitch than the second threaded portion.

摘要： 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.
