ABSTRACT:
In a soil cultivating implement of the kind which comprises a row of rotary power-driven soil working members which extend substantially horizontally and perpendicular to the implement's intended direction of operative travel, the cost of making and assembling the implement is reduced by providing a drive transmission to the soil working members which includes an upright shaft fixed in a sleeve of an open-bottomed gearbox. A bevel pinion is rotatable around the lower end of such fixed shaft and is fastened by adhesively secured pins to the top of one of the spur pinions, each of which is welded to the upper end of a rotary shaft carrying the corresponding soil working member. Blades are provided adjacent the bevel pinion and nearby spur pinions to distribute lubricant to such pinions. One lifts lubricant to the intermeshing spur pinions and another blade further guides same to the bevel pinion.
