Machine with 4 electric/hydraulic functions controlled by just one joy-stick, from the tractor cabin or on the side of the machine. The swing and the height joy-stick operation are proportional, so the operator decides the speed of the movement by joy-stick position. We offer 3 different model sizes for tractors from 25-120 HP all with joy-stick controls. Stump cutting times available in the leaflet page 3. (Photo taken in Norway).
