BULLETIN 1292, U. S. DEPARTMENT OF AGRICULTURE 
on sweet potatoes. The first harvesting operation is cutting vines, 
which is done with a scooter, disk harrow, hoe, or scythe, depending 
on the size of the field, after which they are dragged on with a hayrake 
or scooter, to clear the land preparatory to plowing up the crop with 
a turnplow run from one to four furrows to the row. The next 
operation is to pick up and pile and then haul to the place of 
storage. The last two operations are sometimes done at the same 
time.
