The video clip is designed intentionally to recall the tractor's radar. The tractor is brand new and is ordered with a radar to keep track of the slip and lift the inventory in the presence of one. As seen from the video clip, it just does not work. All tractor tires are full of water about 2,000 liters in total. After the video presented to the dealer, a mechanic from Germany to Bulgaria was sent to remove the defective radar. After the repair and calibration of the new tractor, he was on his way to the same hill without any problems. I think that once we have given our money for something, it should work perfectly. That's why this video was made.
