(5137) Parallel system
A system of parallel field drains with most of the row drains or field drains normal to the collector drains. Parallel drainage systems facilitate mechanisation by eliminating short rows or point rows. Crossable field drains or row drains are constructed between parallel field drains, thus permitting farm equipment to travel greater distances without turning. Land planing or land grading for maximum benefits may improve the field surface between field drains.
