Abstract
A spider wheel for a rotary incorporator for one pass incorporation of chemicals or small grains in previously tilled soil. The incorporator includes two rows of aggressive, large diameter spider wheels supported from a toolbar for rotation in the soil about axes offset at an acute angle to the transverse direction. The spider wheels are to provide good incorporation and a smooth seed bed without hilling or chemical banding. A smaller diameter, depth limited spider wheel on each outermost end of the implement feathers the effect of the angled wheels. The spider wheels include tines having soil working surfaces for good mixing and soil moving action and a large gullet area for good trash shedding and throwing characteristics. The tines on the spider wheels adapted for use in firmer soils, for example, the forwardmost wheels on the incorporator, have end portions which are oriented to reduce scrubbing of the soil for easier entry and reduced vertical force requirements while the inner portions of the tines help to limit depth of penetration of the wheels.
