A slope-level-cut bucket for an excavator includes a first bucket half and a second bucket half. The bucket halves are pivotably connected to each other and movable between a closed position and an opened position. Each bucket half has an excavating edge configured to minimize bucket overlap during cutting of a sloped surface. In particular, the excavating edge includes a plurality of steps. The dimensions of the steps are selected to optimize the cutting of a desired slope of the excavating surface.

The present disclosure relates to grinders in the form of a planer or drum grinder for milling surfaces such as asphalt or concrete. The planer has a multiplicity of cutters oriented in selected arrangements. It is described in the context of a representative system that is added to prime movers, such as skid-steer loaders.

A ditch cutting and excavation spoil removal apparatus creates ditches and land contours while simultaneously removing excavation spoil from the banks of newly created ditches. The apparatus includes an excavation spoil collection box and an adjustable plow saddle that supports a plowshare. The spoil collection box has a vertically adjustable rectangular frame with an open front and bottom. The pivotally mounted plow saddle may be tilted upward and downward through the bottom of the excavation box frame for adjustment of the plowshare and, correspondingly, the depth of the ditch being cut. Excavation spoil is collected in the spoil collection box as the apparatus is moved along the ground surface and is removed by raising the spoil collection box.

An attachment for a skid steer, tractor or similar work vehicle especially designed for creating a swale or ditch in the earth has an arcuate, generally semi-circular steel blade of a predetermined height dimension and a diametrically extending support member welded to ends of the blade. Welded centrally on the support member is a conventional quick-attach plate, a pair of elongated braces extend between and are welded to the quick-attach plate and the arcuate blade.

A boom assembly for a trencher having a boom frame member, a boom drive assembly and a plurality of boom arm assemblies. The boom frame member configured to be attachable to the trencher. The boom drive assembly attached to the boom frame member, having an output shaft that is rotatably actuatable. The plurality of boom arm assemblies extending from the boom frame member, the plurality of boom arm assemblies including at least a first boom arm assembly and a second boom arm assembly. The first and second boom arm assemblies can be of differing length, width, angle and may operate at different speeds.

A grab bucket for making reinforced concrete piles of high load bearing capacity. The grab bucket includes a framework with three wings, a moving assembly movable upward and downward along the length of the framework, a fixed assembly mounted beneath the moving assembly, three grab buckets mounted pivotally to the fixed assembly and having boring teeth oriented outwards, three pushing frames for closing the three grab buckets, and a transmission configured to control opening and closing of said bucket sections in unison.
