Grass is a natural source of nutrition for dairy cattle, and fresh grass contains the most protein and energy. Cows that eat a lot of fresh grass need less protein from concentrates. Lely Exos is the first autonomous solution that harvests and feeds fresh grass multiple times a day, 24/7. By autonomously mowing, transporting, feeding, and fertilising grass, you can maximise the efficiency of the roughage from your own land with minimal labour requirement.

#How does Lely Exos work?

The working of Lely Exos

Lely Exos gets an order from the management system and drives to the field, cuts the desired amount of grass, and fertilises immediately. The machine transports the grass to the barn and distributes it in front of the cows. Accordingly, Exos gets recharged and waits for a new assignment.


The Lely Exos consists of the following parts:

  • Front safety bumper with additional rearward buffer for extra safety.
  • Lightweight, fully opening front cover for easy access.
  • Cameras on the front and back of the machine for timely reducing speed and stopping.
  • GPS for accurate outdoor navigation. Ultrasonic sensors for driving in the barn.
  • Double knife cutterbar that cuts grass perfectly to boost rapid regrowth.
  • Liquid fertiliser applicator directly behind the cutter bar.
  • Transport system with plastic flaps which convey the grass carefully.
  • Lightweight conveyor belt that acts as a bunker floor.
  • Bunker weighing system to register yield and feed results.
  • Electric driven distribution rollers to gently discharge the grass.
  • Right, left, or dual-side unloading conveyor belt for exact and airy distribution.
  • Side skirt with safety bumper.
  • Wheels, individually driven by electric motors with 500-mm wide flotation tires, and an exceptionally low, safe tyre pressure of 0.8 bar.
  • Battery pack, power control, computer and drive control for an energy-friendly electric drive system. These are placed in a low position in the center of the machine.
