+## 10. Field work: grass, clover and alfalfa
+
+The **Fields** tab sends machines out to the farm's mowable crops (grass, clover and alfalfa) by
+itself. AutoDrive drives on the road, Courseplay works the field, and Smart Pickup decides which field,
+which step and which machine. Requires **Courseplay** in addition to AutoDrive.
+
+| Plan | Steps |
+|---|---|
+| **Silage** | Mow → Collect → silo |
+| **Hay** | Mow → Ted → (Rake) → Collect → silo |
+
+### Setup
+
+1. **One marker per field.** Create an AutoDrive marker at the field edge named `F` + the field number,
+   such as `F109` for field 109. Machines drive there on the road before Courseplay takes over. The
+   marker must be within 400 m of the field. Without it, the field shows `!` and nothing is sent.
+2. **Fixed rigs.** The implement must be attached to the tractor (or be self-propelled). The mod never
+   attaches implements.
+3. **Field fleet.** At the bottom of the tab are all vehicles with a mower, tedder, rake or loading
+   wagon, with role and current working width. Tick the ones the mod may send out. Vehicles in a flow,
+   and vehicles you are driving, are never used.
+4. **Parking.** Set an AutoDrive parking spot on each rig. When a rig is done on the field, it drives
+   there. Without parking it stays at the field.
+
+### Width
+
+- Courseplay can work at most **50 m** wide. A rig over 50 m is not sent out (`!! over 50 m` in the
+  fleet).
+- The mod remembers how wide the field was **mowed**. Tedder, rake and loading wagon must be **at least
+  as wide**, so every lane covers what the mower laid down. With Unrealistic Pack: set the mower and the
+  loading wagons to the same width, such as 40.8 m.
+
+### A field
+
+Click a field in the table to select it. Below the table:
+
+| Option | Meaning |
+|---|---|
+| **Plan** | Silage or Hay |
+| **Mode** | *Manual*: the field waits for **Start now**. *Auto*: the field starts by itself when ready |
+| **Rake** | Hay only: rake before collecting. Off by default, because wide loading wagons collect spread hay |
+| **Force storage** | Pick silos. Without a choice the nearest silo with room that takes the goods is used |
+
+A field is **ready** when at least 90 % of it is in the harvest window. The status shows the share,
+such as `Waiting 72 %`. **Start now** works from 50 %. **Stop field** stops the machines on the field,
+and the field is ready again.
+
+**Field silo:** a silo within 150 m of the field is an intermediate store with short trips. The mod
+shows `! Field silo … is not emptied home` if no *Out of building* flow has it as a source. Create such
+a flow to bring the silage home.
+
+### Status and reasons
+
+| Status | Meaning |
+|---|---|
+| **Waiting / Ready** | The field is growing / ready (Manual waits for Start now) |
+| **Mowing, Tedding, Raking, Collecting** | The step is running |
+| **Done** | All steps are done. The field becomes *Ready* again once it has grown |
+| `waiting for a free mower` | All rigs with the role are busy |
+| `loading wagon too narrow: 20 m < mowing width 40.8 m` | Increase the loading wagon's width |
+| `Courseplay could not create a course` | Retried after 5 minutes |
+
+Log lines in `log.txt` start with `ADSmartPickup: F109 …`.
+
+### First test
+
+1. Set one grass field to **Manual** and **Silage**, with an `F` marker and one mower and one loading
+   wagon ticked.
+2. Press **Start now**. The mower drives to the marker, Courseplay mows the field, and the rig drives
+   home.
+3. The loading wagon goes out. When it is full, AutoDrive empties it in the silo and drives back, and
+   Courseplay continues. The field shows **Done**.
+4. Then try **Hay**, and finally **Auto**.
