# Thresh — Grain Threshing Reference

Quick-reference skill for threshing principles, combine harvester settings, and grain loss management.

## When to Use

- Understanding threshing mechanisms and methods
- Setting combine harvester parameters for specific crops
- Reducing grain loss during harvest
- Planning harvest timing and operations
- Post-harvest grain handling and drying

## Commands

### `intro`

```bash
scripts/script.sh intro
```

Overview of threshing — history, principles, and modern methods.

### `mechanisms`

```bash
scripts/script.sh mechanisms
```

Threshing mechanisms — cylinder types, concave settings, rotor systems.

### `crops`

```bash
scripts/script.sh crops
```

Crop-specific threshing settings for major grain crops.

### `loss`

```bash
scripts/script.sh loss
```

Grain loss sources, measurement, and reduction strategies.

### `timing`

```bash
scripts/script.sh timing
```

Harvest timing — moisture content, maturity indicators, and weather.

### `postharvest`

```bash
scripts/script.sh postharvest
```

Post-harvest handling — drying, cleaning, storage, and quality.

### `examples`

```bash
scripts/script.sh examples
```

Practical threshing scenarios and troubleshooting.

### `checklist`

```bash
scripts/script.sh checklist
```

Pre-harvest and threshing operations checklist.

### `help`

```bash
scripts/script.sh help
```

### `version`

```bash
scripts/script.sh version
```

## Configuration

| Variable | Description |
|----------|-------------|
| `THRESH_DIR` | Data directory (default: ~/.thresh/) |
