INVENTIONS & APPLIANCES OF INTEREST TO AGRICULTURE.

DISC HARROW. The shafts of the two rear gangs here are made longer than those of the front gangs, and on their outer ends are mounted an extra disc. This disc is of

less diameter than the others. It pulls down the ridge of the furrow left by the. end main discs, and leaves the land level. LISTER CULTIVATOR. At the forward ends of the stub tongue of each outside gang is a double bracket on which are two shafts. On these rollers are slidably and turnably mounted. Th® rollers work between two bars of th®

frame. Draft chains are carried from the frame to the middle of the tongue. This -»* hitch allows the gangs to he moved laterally while maintaining their direction parallel to the row. PLOUGH HARROW. On this plough is mounted a notched segment with a hand lever to which is attached the spring bar which draws the harrow. The setting of the lever adjust® the angle of the harrow teeth, and this

angle is maintained by a stop nut on the spring bar abutting the harrow frame. When the plough is backed the spring bar angles the harrow bars so that the teeth slide over the ground. FERTI LIS ER DISTRIBUTOR. Three sections of false bottom are set over the conveyor here. These carry most of the weight of the fertiliser, falls between them to the conveyor which carr’es it to the discharge chute. Over

discharge outlet is a spring-held cover. Arms projecting laterally from this cover are struck by tappet arms mounted on the conveyor shaft. Thus <he outlet is o]iened and closed to deposit fertiliser at intervals which may be regulated. DISC ATTACHMENT FOR GANG PLOUGHS. This attachment is designed for orchard work. At the end of the rear beam ii bolted a bracket which ends in two in* tegral horizontal flanges. The arm of the attachment is pivoted between these,

and is hold outwardly bv a spring. Th® bracket is attached with only one bolt, so that it will rise if it strikes any heavy obstruction. If the arm strikes a tree the spring allows it to swing inwardly. POTATO CUTTER. In its simplest form this cutter cuts a potato in four pieces without touching the ends which usually have sprouts. One

blade is extended upwardly, and faced with wood to form the handle. Auxiliary blades may be attached to cut potatoes into six pieces.
