The Silva Nova Tree Planting Machine during the 1980s [Planteringsmaskinen Silva Nova på 1980-talet]

The Silva Nova tree planting machine prepared forest soil and planted tree seedlings mechanically. The Silva Nova was born around 1977, and was continually refined and used operationally in Sweden up until 2001. This video is in Swedish and was produced during the mid-1980s. It shows an outdated version of the Silva Nova equiped with the Wadell cone scarifier. I have shared this video solely for educational purposes.
