Hunter reports a similar implement in
common use on the dry-farms of the Columbia Basin. Spring tooth
harrows are also used in a small way on the dry-farms.
They have no special advantage over the smoothing harrow or the disk
harrow, except in places where the attempt is made to cultivate the
soil between the rows of wheat. The curved knife tooth harrow is
scareely ever used on dry-farms. It has some value as a pulverizer,
but does not seem to have any real advantage over the ordinary disk
harrow.
Cultivators for stirring the land on which crops are growing are not
used extensively on dry-farms. Usually the spring tooth harrow is
employed for this work. In dry-farm sections, where corn is grown,
the cultivator is frequently used throughout the season. Potatoes
grown on dry-farms should be cultivated throughout the season, and
as the potato industry grows in the dry-farm territory there will be
a greater demand for suitable cultivators. The cultivators to be
used on dry-farms are all of the riding kind. They should be so
arranged that the horse walking between two rows carries a
cultivator that straddles several rows of plants and cultivates the
soil between.
