We'd buy feed at a farm supply store or let the cows graze in a meadow, right?
Here, men and women cut 4-5' grass stalks in the jungle clearings with machetes. The grass is loaded into a frame and hoisted onto the shoulder to be walked out to the stall. If the grass is being sold, waiting motorcyclists put the frame over their shoulders and away they go = wide transportation.
Note the 2 dark heaps of grass in the frame and the tin can tied to the wood. The can acts as a speaker for the man's portable radio.
