INVENTIONS & APPLIANCES OF INTEREST TO AGRICULTURE.

TRACTOR CLUTCH CONTROL.’ A hand lever is mounted in a quadrant on the coupling bar in front of the drivers seat. From the lever a flexible wire or chain passes over a guide pulley

and connects to the clutch operating lever. The pulley is located at the head of the king bolt, so that turning action does not have any effect on it. A pull on the hand lever engages the clutch. TRACTOR CULTIVATOR. The main draft bar of the multiple unit cultivator is connected to the tractor by two inwardly inclined links which rest upon the arch bar frame, and can move sideways in relation to it between

variable stop limits. The whole is adjustable vertically by hand lever, the lowered position lifting the discs from the ground, as shown by dotted lines. MOWING MACHINE. This is a multiple unit machine, the units being carried in echelon from a stiff oblique cross frame carried ahead of the tractor and power unit. A power shaft is located on each side of the

engine, and at various points power take-offs are located and connected through shafts and universal joints to the cutter bar operating pitman. WEEDER. The knives are L-shaped, the upstanding end connecting to a vertical plate which is suspended from a rod, and pulled by an oblique hinged link. Each knife is quickly replaceable by removing

its bolts. Any knife-holder’ unit may rise against the springs to ride over stones, while the whole gang is adjustable for depth by the 1 -nd lever.

FOUR-HORSE EQUALISER. One double tree here is connected by pivot links to the cross bar, while the other is connected by a chain, one end of which is adjustably secured by a bolt passing through a link, the other end

passing round a sheave in the main evener bar, and thence to th*e other end of the. first cross bar. The two bars are connected by straight links at the centre and oblique links near the left side.

FRUIT GRADER. Each grader unit consists of two circular end plates connected by a semicircular plate. Parallel to and inside one edge of the latter is a rod whose distance from the hub is adjustable. The whole rotates for a half circle clockwise and then reverses. The hubs decrease in

size to tlie right and rotate clockwise continuously. Fruit; fed from the left, falls between rod and hub to the belt below, or, if. too large, is carried over to the next units, whose openings are in* creasingly larger. ,
