ABSTRACT:
A seedling transplanter has a main frame securable to a drawing vehicle by a draft bar and supported for movement over a piece of ground in which seedlings are to be planted. Coulter assemblies are mounted on the main frame for cutting a furrow as the frame transverses the ground, with each of the coulter assemblies including a disk having a substantially planar main portion and a bent portion, with the amount of bend of the latter portion determining the width of the furrow. The draft bar is pivotally mounted on the main frame for swinging movement in a substantially vertical plane so as to permit the transplanter to traverse rocks and similar objects within the soil without the coulter disks being lifted from the ground, with a stop being provided on the draft bar for permitting the conventional lift provided on the towing tractor to cause the coulter assemblies to be disengaged from the ground as desired. When wheels are employed to support the main frame on the ground or other surface being traversed, such wheels are mounted in a simple manner for individual toe adjustment in order to permit the toe of the wheels to be set such as to facilitate towing of the transplanter.
