is held by a vertical stud fixed to the frame considerably 

 behind the steering wheel. This position of the draft stud 

 (the subject of a special patent) gives the necessary liberty

and power to the steering wheel, and enables it to lead the 

 implement at almost any angle out of the line of the pulling 

 rope. On the short end of the turning lever is a chain com- 

 municating with a quadrant on the crank axle, and as the 

 lever is pulled round the chain acting on the quadrant turns 

 the axle, lifts the frame, and raises the tines out of the 

 ground. The plan of operation is as follows : As soon as 

 the cultivator is brought up to the headland the reverse pull 

 brings the lever round and lifts the tines out of the ground, 

 and they are held up by a catch ; when lifted the required 

 height the lever strikes against a stop, and the implement 

 turns into new ground ; the man (who never leaves his seat) 

 releases the catch, the tines drop into the ground, and the 

 implement is drawn across the field. 



The principal advantages of this implement are as fol- 

 lows : Its size is only limited by the power of the engines, 

 which thus may be used to their utmost capacity. It smashes 

 up the soil, working steadily, and always preserving a per- 

 fectly uniform depth. Even the largest implements of this 

 description require only one man in attendance. In rounding 

 round no additional work is required, and scarcely any time 

 is lost, whilst the implement, however wide, at once moves 

 into new land, leaving small and irregular headlands. On 

 average soil 30 to 50 acres per day may be efficiently culti- 

 vated. Ridging bodies attached to the frame of the culti- 

 vator make an effective and easily handled ridging implement.
