Abstract: A shroud retention system for a work tool is disclosed. The shroud retention system may have an adapter attached to the work tool, and a shroud having a channel that slides over the adapter. The channel may have a retainer slot. The shroud retention system may further have a spring assembly disposed in the channel and connectable to the adapter. The spring assembly may have a slide compressor that can slide within the channel relative to the adapter. The slide compressor may have a compressor mating feature. The spring assembly may further have a resilient member disposed between the adapter and the slide compressor. The shroud retention system may have a retainer plate disposed in the retainer slot. The retainer plate may have a retainer mating feature that mates with the compressor mating feature such that the retainer plate and the slide compressor are engaged in a locked position.

Abstract: A ground-engaging tool system includes an adapter attachable to a work implement and a ground-engaging tip that is releasably connectable to the adapter. To releasably mate the adapter and the tip, the adapter may include a projecting lug post that locks and unlocks with a rotatable, latch-like retainer in the tip. The lug post may be a frustum or frustoconical structure having a truncated flat and an exterior side surface that intersect at a peripheral edge. The shape of the truncated flat, peripheral edge, and exterior side surface may further be delineated by a first radius and a second radius of different dimensions, or by radii having first and second centers that are not coincident in location on the truncated flat.

Abstract: A shroud retention system for a work tool is disclosed. The shroud retention system may have an adapter attached to the work tool. The shroud retention system may also have a shroud that slidably engages with the adapter. The shroud may have a retainer slot. Further, the shroud retention system may have a spring assembly disposed in the shroud. The spring assembly may have a block that slidably moves relative to the adapter. The spring assembly may also have a resilient member disposed between the adapter and the block. In addition, the spring assembly may have a retainer disposed in the retainer slot. The retainer may engage with the block. The retainer may have at least one recess disposed on the retainer front face or on the retainer rear face. The recess may extend partway toward the other of the retainer front face or the retainer rear face.
