## Abstract

A brush arrangement of an apparatus includes a brush connected to a brush support. The brush support can be or include at least one four-bar linkage, trails the outlets of the seed metering device. The brush sweeps fine loose material over seeds placed on the soil surface allowing rocks to be left in place in/on the soil while the deposited seeds are lightly covered with soil by the brush. The brush arrangement can be coupled with soil manipulation apparatus, e.g., including a tool/tine support, onto which one or more soil engaging tools mount(s). The soil engaging tool may include or be at least one knifepoint, sweep, disc, blade, or other tillage equipment to engage into the soil and loosen compacted or crusted soil ahead of depositing the seeds. Brush breakout can be accommodated by a breakout coupler and optional adjustable breakout force.

## Claims

### Claim 11 (depends on 1)

The apparatus of claim 1, wherein the soil manipulation apparatus comprises at least one soil engaging tool on a tool support to loosen rocky, compacted or crusted soil to provide loose fines for sweeping by a respective one of the at least one brush.

### Claim 12 (depends on 11)

The apparatus of claim 11, wherein the at least one soil engaging tool comprises at least one of a grader blade, plough blade or disc, disc opener, ripper tooth, tiller blade, or a combination selected from at least two or more thereof.

### Claim 13 (depends on 11)

The apparatus of claim 11, wherein the soil manipulation apparatus comprises a breakout with adjustable preload or lift mechanism to lift the at least one soil engaging tool and/or the tool support.

### Claim 14 (depends on 11)

The apparatus of claim 11, wherein the breakout coupler enables the brush arrangement to lift or fall, matching motion of the at least one soil engaging tool and/or the tool support.

### Claim 15 (depends on 1)

The apparatus of claim 1, wherein the apparatus comprises multiple breakout coupler attachment positions.

### Claim 16 (depends on 1)

The apparatus of claim 1, comprising rest position means for controlling a rest position of the brush mechanism and/or the at least one brush.

### Claim 17 (depends on 16)

The apparatus of claim 16, comprising at least one biasing means to control the rest position of the brush mechanism as well as controlling down force provided by the at least one brush to the soil.

### Claim 18 (depends on 17)

The apparatus of claim 17, wherein the biasing means comprises at least one spring, at least one weight, at least one elastomer member, or a combination of any two or more thereof.

### Claim 19 (depends on 1)

The apparatus of claim 1, comprising a position lock for locking the position of the brush mechanism to restrict a degree of freedom of movement of a respective one of the at least one brush.
