Sure. This was the only reforestation automaton made (ПЛА-1) in the USSR. Take any Soviet reference for mechanical planting of forests - it will be there. Technically its an add-on to large forest plough ПКЛ-70 supplied with cassette feeder. http://goo.gl/RtVgTd <- Page 21, sorry for Russian source. It takes 4000 saplings at once, and goes at 6 km/hr, can plant every at 0.5m, gives you 12K saplings/hr. You have to recharge it with cassettes with saplings. Nothing fantastic, ideally works for forest plantations in the Northern hemisphere.
