It fits into the arms of a loader or replaces the cutting arm of a Tree Pruner shovel. Its adaptation is by fasteners and plugs. The use as discs or as blades, is alternative.
The blades are replaceable one by one, using screws. Cut branches up to 4 cm. Diameter and carries a cutting speed of up to 5 km. / hour . Its speed, cycles per minute, up to 500 minute oscillations is adjustable, to 200 also cuts well.
The cut of the blades is more perfect than that of the discs, matching the pruning shears. It does not make a saw, which allows to work in summer and with the open windows of the tractor. Use a remove and drop system to dislodge branches from the top of the tree. In vertical pruning is not necessary, but in horizontal pruning.
The sharpening time of the blades is much longer than the sharpening of the discs. Since cutting at low revolutions can work with pumps of 40 liters minute, which allows to work with the same pump of the tractor in most of these models. The cut is produced by means of a double crankshaft with two lines of opposing blades as well as scissors, with a cutting power much higher than pneumatic scissors.
Due to its high performance, there is no oil heating. Its construction is very robust, its moving parts have oversized bearings, and the friction between the two blade lines is nylon, all in replaceable parts.
Tree Pruners machines are mounted in:
- Loader arms
- Pallet truck
- Angular Lift Mast
