It is not easy!
It doesn't seem easy at all to bale vetiver, the need of doing it may probably go beyond building a house:
first of all the hay has to be cut and left on the ground to dry, has then to be broken up passing it over a few times, then alleys have to be lined up.
The cut leaves and stems are stiff and they finish up to clog the baler with the result of a lot of arm work to be done. the author of the video claims that with a little luck you can bale some ten meters before the baler chokes....
On the other hand a feedback comment on the video reports that some mistakes have been done and the job could have been faster without them.
More work has to be done on the field to find a more practical way to bale.
But why bale it?
