Narrow neck

For using this device, it is frankly disappointing. Offered in a variety of brands and colors with the same engines, it has enough power, but ...
It is not practical. You should know that the main grinding is done by side chute when the branch diameter exceeds several millimeters. Downstairs is a tray with two blades that cut twigs and branches. But on this model, the channel is long, narrow and difficult to pass branches, nature rarely produce rectilinear branches: Many do not even pass by pushing strongly. So we must redraw all the branches in straight pieces.
We must prefer a short chute model, broad and oval.

Then the sharpening of blades is tedious because of disassembly: Both hopper and chute must be registered to access it.
Provide sharpenings or fairly frequent replacement, every 10 to 15 hours.
Unless modified with laying rubber washers, some tabs have a tendency to break at the belt cover and the tank.
Also check the tightness of the wedge holding the belt pulley, the centrifugal clutch is also vulnerable if you have the misfortune not to crank the engine more than 2000 T / min before beginning grinding. Personally I mounted a small tachometer.
All bolts should be checked and tightened.

Then, for grinding from the top, make sure never to fold in half vegetation handles are introduced, which would block in the cone of the hopper.
Finally a little steep woody debris pass through the bottom holes without being shredded by the hammers. making pieces of 20-30cm.
In short, once the heavy mulching wanted done, I did not keep the material I had.
but hey, it works .... headsets provide efficient, more vibration in the hands is very important. The engine, Chinese manufactured under license Honda seems without problems.
