4.2 | COMMAND Tractor Requirements

Tractor Requirements

COMMAND's tractor requirements are as follows:

  • The tractor must be capable of providing the necessary power supply for COMMAND as specified in the next section.
  • The tractor SCVs or Auxiliary Control Valves must be compatible with the valve types specified in Hardware Overview. 
  • The tractor must be ISOBUS ready, if not we recommend the installation of a Greenstar ISOBUS retrofit kit.
  • The tractor must have a suitable method of manually controlling implement functions.
  • The tractor must be in good running order, with hydraulic outputs working correctly when manually controlled prior to the installation of COMMAND.

Implement Requirements

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.

Suitable Implement Types

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

  • Implements with a single hydraulic height control function, 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 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 Suitable Implement Types

  • 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.

COMMAND is currently still in development for use with implements that require pitch angle steering of a boot, such as pitch-controlled tile plows for ditching applications.
