 AGRICULTURAL MACHINERY 173 an endless belt driven from the wheels, and discharging ] to the point where it is to be deposited by horsethe hay into the rack as it follows the machine. ! power. ir the hay is to be stacked, a drag-rake and stacker, as shown in Fig. 28, may be employed. The drag-rake consists of a triangular frame, having a supporting wheel at each angle, and a rake head pivoted to the frame parallel with the base of the triangle. The rake head can be lowered so that the teeth sweep the ground and take up a large quantity of hay. The rake is then driven to the stacker and the load is deposited on the elevating rake, which is hoisted by a system of pulleys and ropes, and discharges the hay on to the stack. If hay is to be shipped it is advantageous to bale it, a press operated by horse-power (Fig. 29) being used for the purpose. The hay-press is provided with a hopper into which the loose hay is fed in front of a plunger moved by means of a lever, to which the horses are attached. The action of the lever is then reversed, the plunger retreats, a new charge of hay is fed, and the movement is repeated. In this way the hay is pressed into a compact bale, wires Fig. 27.- Hay rake and loader. are passed around it and secured, and the mathe by I in g carrier runnmg on tracks above mow, rbbehay bdone ^ shipping, the freights are greatly reduced.
