 172 little wood, and this construction enables all joints to be made much stronger and more permanent. A recent form of mower is shown in Fig. 22. The cutter bar is of the well known type. The draft evener slides in guides upon the tongue, and is connected with the coupling bar in such a manner that the weight of the entire cutting apparatus is taken off the ground, thus producing a very light running machine. Levers are provided for tilting the finger bar for cutting closer or higher, and a second lever raises the coupling frame and finger bar in passing obstructions. The latter operation may also be performed by the foot of the operator pressing upon the curved lever at the rear of the axle.

bars, which extend rearwardly between the teeth, prevent the hay from clinging and ensure its discharge.

O'". Sirin (lelivt In Fig. 25 is shown what is known as a side-delivery horse rake, which takes up the hay by means of a revolving toothed cylinder, from which it is taken by a toothed carrier and delivered upon a. transversely moving apron. The hay is thus discharged from the machine m a continuous wind-row, extending in a direction parallel with the line of draft of the machine. Another labour-saving machine is the tedder (rig. - >) used for spreading and turning the hay while it is being cured.

Fig. 23.—Lawn Mower. For mowing lawns, the machine shown in Fig. 23 is used. Instead of a reciprocating knife, the lawn mower employs a revolving reel, having spirally-arranged knives which impinge upon a stationary knife and cut the grass with a shearing action which is more effective. m short and tender grass than a reciprocating knife. The gauge roller at the rear of the machine regulates the height of the cut. Instead of raking hay by hand, the farmer now employs a horse rake, wdiich is illustrated in Fig. 24. The hay is raked by the spring teeth, and when a sufficient quantity to form a wind-row has accumulated, the driver pi esses with his foot upon a lever operating a clutch and connecting the rake head to the driving wheels. The rake is thus raised and the

load dumped by the action of the team.

This machine is mounted on two wheels, and carries m bearings at the rear of the frame a multiple-cranked shaft, provided with a series of forks sleeved on the cranks and having their upper ends connected by links to the frame. As the crank-shaft is driven from the wheels by proper gearing the forks move upward and forward, then downward and rearward, in an elliptical path, and kick the hay sharply to the rear, thus scattering and turning it Ihe tedder forks are hinged to the arms and are provided with cranks connected by rods to springs on the arms, being thus enabled to yield and avoid breakage by striking an obstac e. For loading the hay on waggons a combined hay rake and loader, shown in Fig. 27, may be used This machine is coupled to the rear of the hay-rack ana is drawn over the field, the revolving hay rake picking up the hay and feeding it to the elevator, which consists ot
