We are on the rolling hills of Lake Trasimeno (PG) for a day dedicated to cleaning the olive trees before the start of the olive harvest. At work with its generous horsepower we find the king of tracked tractors, the New Holland TK SMARTRAXX SERIES. In this case it is a special model because it is number 1/100 of the CENTENARIO TRATTORI FIAT series. Attached behind a large mulcher from the BERTI company model tfb 200 SERIE C which as an optional accessory has a useful mechanical brush cutter arm to also remove the grass between the rows of olive trees.
