Hello everyone, thank you for your warm comments!
As for Bittah_Commander's question:
The spiked "tentacles" are inserting the ground and loosening the roots hold. Now, if you notice the bottom front, you'll see a bucket/blade that is similar to a construction tractor's front. When the vehicle drives over the loosen plant, it uses this part to collect the plant, with the help of the "tentacles", and from there its being sucked into the tank.
