# 4.2 | Tractor Requirements

## Tractor Requirements

**COMMAND's** tractor requirements are as follows:

- Provide a suitable power supply as specified in Section 4.3.
- Have compatible SCVs or auxiliary control valves
- The tractor does not need to be ISOBUS-equipped; however, upgrading to ISOBUS is strongly recommended to provide the necessary connections (e.g. implement breakaway connector).
- Be capable of manual implement control.
- Be in good working condition with fully functional hydraulics.

If any requirement in this section cannot be met, installation should not proceed.

## Implement Compatibility

### Supported Implement Configurations

**COMMAND** is currently suitable for use with the following types of implements:

- **Implements with a single hydraulic height control function and a single receiver**, i.e. requiring a single valve. This includes implements with multiple height cylinders if the cylinders are linked together and controlled by the same valve. e.g. John Deere tractor-pulled scraper.
- **Implements with a single hydraulic height control function, single receiver, and a single cross-slope/tilt control function**, i.e. requiring a single separate valve for each (2 total). e.g. JN&R tractor-pulled scraper with cross-slope / tilt cylinder.


### Future Configurations

- **Implements with a single hydraulic height control function and dual** **receivers**, i.e. requiring a single valve for height control and a single valve for cross-slope control with both a left and right implement mounted receiver.
- **Tandem implements (convoy) each with a single hydraulic height control function**, i.e. one valve controls front scraper height and another valve controls rear scraper height.
- **Implements with two separate hydraulic height control functions**, i.e. two separate valves are required to control each side of the implement. e.g. grader-style blades with independent left/right control.
- **Two implements towed in tandem with a single height control function each**, i.e. requiring one valve for each implement. e.g. Two John Deere tractor-pulled scrapers pulled behind the tractor.

## Implement Definitions

The naming conventions below will help to avoid confusion later:

**Single implement** - One single blade with one receiver positioned in centre (single-axis or dual-axis) (May or may not be accompanied by IMU).

**Tandem implements** - Two blades in front/behind one another as a train, each with a single receiver positioned in the centre (single-axis control only).

**Dual receiver** - One single blade with two receivers positioned on the left and right sides of the blade for dual-axis control. The tilting point is assumed to be the centre of the blade edge, in the middle of the two receivers.
