The Landoll 7430 Vertical Harrow is designed
to be pulled by tractor equipped with a double lip
or clevis type hitch. If your tractor is not equipped
as such, you need to purchase the hitch from your
local tractor dealer. If your Vertical Harrow is
equipped with the clevis option, this should be re-
moved. The clevis option is only for transport use.
