Abstract
A cultivating tool propelled by a walking attendant has sheet metal tines mounted on a rotating axle for rotation therewith. The tines are channel-shaped with axle-accommodating apertures through the flanges and also through the webs. When the axle is engaged through the flange apertures, the ends of the web engage the soil flatwise so as to provide a hoeing action; and when the axle is engaged through the web apertures, the ends of the web engage the soil edgewise so as to provide a chopping action.
Claims5
A cultivating tool comprising,
- an elongate handle,
- an elongate axle on the handle with its longitudinal axis transverse to the length of the handle,
- a series of sheet metal tines,
- each of the tines being channel-shaped, having flange portions connected by a web portion,
- the web portion at each end of the tine extending beyond the channel portion and having a flat surface lengthwise between relatively thin side edges,
- and means for mounting the tines at their mid portions on the axle in two different modes comprising apertures through the tine web portion and apertures through the flange portions, said apertures of said tine web portions and of said flange portions being sized to be engageable over said axle whereby, when the apertures through the web portion of one of the tines are engaged over the axle and the tool propelled along the ground, the thin edges of the tine web portion ends are presented knife-like to the ground, and when the apertures through the flange portions of the tines are engaged over the axle, the flat ends of the tine web portions are presented hoe-like to the ground.
