초록 ▼

An elongated downwardly opening housing is provided for lengthwise advancement over the ground and includes mounting structure for dependingly supporting the housing from a farm implement tool bar. The housing includes front and rear transverse journaled horizontal shafts each having a pair of axially spaced circumferentially spiked wheels mounted thereon for rotation therewith. Corresponding ends of the shafts project outwardly through opposite sides of the housing and have aligned sprocket wheels mounted thereon. The sprocket wheel carried by the forward shaft is at least slightly greater in diameter than the sprocket wheel carried by the rear shaft and an endless chain is trained over the sprocket wheels drivingly connecting the forward shaft or front shaft to the rear shaft. As the housing moves over the ground along rows in which crops are to be planted the spiked wheels or disks carried by the front shaft are turned by their engagement with the ground and the soil over which the spiked disks carried by the front shaft roll is loosened. Then, as the same strip of ground surface is contacted by the spiked disks carried by the faster rotating rear shaft, the loosened soil is further loosened and mulched. In addition to this structure, the housing includes a sheet of flexible resilient material extending between the sides of the housing forming the front, top, and rear walls therefor. At the rear end of the housing, this sheet of material projects downwardly below the sides of the housing to define a flexible ground sweep. Additionally, the housing is provided with chemical spray discharge structure whereby a suitable weed retardant or other chemical may be sprayed onto the ground or soil being acted upon by the spiked disks carried by the front shaft. One form of the invention disclosed is mounted for vertical floating movement to compensate for irregular ground surfaces and includes adjustable ground engaging gauge wheels.
