Abstract
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.

A slope-level-cut bucket, comprising:
- a first bucket half pivotably connected to a second bucket half, the first bucket half and the second bucket half movable about a first axis between a closed position and an opened position, each of the first bucket half and the second bucket half having a top wall, a front wall, a rear wall, a side wall and a cutting wall, the cutting wall having a plurality of steps, each of the first bucket half and the second bucket half having a rim defined by the top wall, the front wall, the rear wall, and the cutting wall, and the rim of each cutting wall defining an excavating edge.
A slope-level-cut bucket, comprising:
- a first bucket half pivotably connected to a second bucket half, the first bucket half and the second bucket half movable about a first axis between a closed position and an opened position, each of the first bucket half and the second bucket half having a top wall, a front wall, a rear wall, a side wall and a cutting wall, the cutting wall having a plurality of steps, each of the first bucket half and the second bucket half having a rim defined by the top wall, the front wall, the rear wall, and the cutting wall, and the rim of each cutting wall defining an excavating edge,
- wherein the rear wall of the first bucket half and the second bucket half is on a first plane and the excavating edge of the first bucket half and the second bucket half is on a second plane, the first plane oriented transverse to the second plane, defining a first angle therebetween, the first angle between about 72 degrees and about 79 degrees, and
- wherein a planar surface of the side wall of the first bucket half and the second bucket half is on a third plane and the top wall of the first bucket half and the second bucket half is on fourth plane, the third plane oriented transverse to the fourth plane, defining a second angle therebetween, and the second angle between about 25 degrees and about 45 degrees.
A slope-level-cut bucket, comprising:
- a first bucket half pivotably connected to a second bucket half, the first bucket half and the second bucket half movable about a first axis between a closed position and an opened position, each of the first bucket half and the second bucket half having a top wall, a front wall, a rear wall, a side wall and a cutting wall, the cutting wall having a plurality of steps, the steps adjacent to the front wall of the first bucket half and the second bucket half being of a greater length than the steps adjacent to the rear wall of the first bucket half and the second bucket half, the first bucket half and the second bucket half having a rim defined by the top wall, the front wall, the rear wall, and the cutting wall, and the rim of each cutting wall defining an excavating edge, the first bucket half and the second bucket half each having a distal end and a proximal end, the side wall and the cutting wall of the first bucket half and the second bucket half tapering toward the distal end of the first bucket half and the second bucket half,
- wherein the rear wall of the first bucket half and the second bucket half is on a first plane and the excavating edge of the first bucket half and the second bucket half is on a second plane, the first plane oriented transverse to the second plane, defining a first angle therebetween, the first angle between about 72 degrees and about 79 degrees, and
- wherein a planar surface of the side wall of the first bucket half and the second bucket half is on a third plane and the top wall of the first bucket half and the second bucket half is on fourth plane, the third plane oriented transverse to the fourth plane, defining a second angle therebetween, and the second angle between about 25 degrees and about 45 degrees.
