Fig. 2. Horizontal View of Working Parts. 
Description of Working Parts of Cultivator, 
a. Frame in stout bar iron attached to hind platform of engine. 
6. 5-cranked axle, with 6-inch throw. 
c. Lever arms carrying digging-tines, bolted on to cranks and attached by swinging 
bars at end to frame (a). 
d. Digging-tines, 2-pronged with broad flat blades, fixed one before and one behind the 
crank. 
e. Driving-wheel of axle actuated by pitch-chain from main shaft of engine. 
The surface operated upon was l - 75 mitres (equal to 5 ft.

engine was driven at the rate of sixty revolutions per minute,
