IMPROVED HARROW.

Hans Iver Lund, Charlotte, Iowa.--The object of this invention is to

furnish an iron harrow which shall be light, strong, and durable,

of less draft than an ordinary harrow, of less size, inexpensive

in manufacture, and effective in operation, breaking up the lumps

thoroughly, and stirring up the soil evenly. The harrow is designed

to be made in three sections, all exactly alike, one, two, or three of

which may be used at a time.
