A plow attachment for an excavator, including a distal portion having elongated curved front and rear walls, and an elongated top wall, a pair of oppositely disposed elongated hook-shaped side walls connected to the top, front and rear walls and defining an elongated trough, a soil-deflecting wedge portion extending from between the sidewall portions and positioned opposite the top wall member. The plow attachment includes a proximal portion connected to the distal portion and having a flat skid plate member, a structural member connected to the flat plate member, and a hoe connecting member connected to the structural member.

A shearing implement for use with an excavator is disclosed. The shearing implement comprises a thumb having a grasping side and a cutting side and being pivotably attachable to the boom. A shearing blade member is pivotably attached to the cutting side of the thumb. A linear actuator has a first end attached to the shearing blade member and a second end attachable to the boom or the thumb so that extension and retraction of the linear actuator causes the shearing blade member to rotate relative to the thumb.

The adjustable fork bracket may comprise a left fork bracket, a right fork bracket, a left rachet strap, and a right ratchet strap. The adjustable fork bracket may be an accessory for coupling a fork to a front edge of a bucket of construction equipment. Tines of the fork may enable the construction equipment to lift materials using the bucket. The left fork bracket may comprise a left primary tine on the left side of the bucket and the right fork bracket may comprise a right primary tine on the right side of the bucket. The left rachet strap and the right ratchet strap may pass behind the bucket to retain the adjustable fork bracket in place. A primary tine separation distance between the left primary tine and the right primary tine may be adjustable.

A grapple assembly includes a grapple with two opposing arms connected to a boom arm of an excavator for engaging an attachment plate connected to an excavator attachment, such as a bucket. The attachment plate includes two outwardly extending plates creating two receivers for engaging the grapple arms. The attachment plate allows an operator of the excavator to use the grapple to handle large items, and to use the grapple to grab the attachment plate connected to a bucket to use the bucket to handle small items without having to disconnect the grapple from the boom arm and attach the bucket to the boom arm.

A dump liner device includes a receptacle, such as a bucket of a digger, having a high side and a low side when in a dumping position. The receptacle has a concave interior surface for holding material in the receptacle while in a holding position. A connection edge of a flexible panel is coupled to the high side of the receptacle. The panel conforms to the interior surface of the receptacle but is unconnected to the receptacle except along the high side such that the panel is gravitationally urged away from the interior surface of the receptacle in the dumping position to facilitate dumping of the material from the receptacle as the receptacle is moved into the dumping position from the holding position.

Provided is a manipulation apparatus for a rockbreaker, the apparatus comprising a manipulation tool defining at least one substantially flat surface, a mounting configured to swivelably mount the manipulation tool on the rockbreaker such that an angle formed between an axis along the flat surface and an impact axis of the rockbreaker is infinitely adjustable. Apparatus further includes an actuator arrangement configured to swivel the tool so that the flat surface is selectively and infinitely adjustable relative to the impact axis to facilitate manipulation of material by the tool.
