Transplanting machines, as illustrated in Figure 39, are in general use for setting vegetables, especially cabbage and tomato plants. They do the work better and more rapidly than is commonly done by hand, and as a rule with less expense. In many sections it is impossible to secure the necessary help at the time of planting and in such localities machine planters are indispensable. They are very simple to operate, but a steady team and a careful driver are important factors. A narrow shovel opens the furrow, and the machine moves as slowly as may be necessary to enable two men or quick, careful boys, to drop the plants alternately in the narrow furrow. Shoes or rollers close the furrow, pressing the soil very firmly to the roots and stems. Water may be used with each plant if desirable. By quick work the plants may be set 15 inches apart or even closer.
