The present invention provides a scraper mechanism for a disk blade including a wear ring attached to the rim of a rotary scraper and releasably biased toward and held in planar contact with one side of a disk blade. The wear ring is molded from a low friction, long-wearing material, such as molded nylon. The low friction material eliminates the metal to metal contact of conventional rotary scrapers and therefore eliminates the squeal associated with rotary scrapers. Also, wear of the scraper is audibly detected when the wear ring is worn away, thereby alerting the operator that maintenance is required.

An automatically engageable and disengageable drive coupler mechanism is provided in which separate drive and driven couplers are automatically coupled to and uncoupled from each other simply by moving the couplers into and out of contact with each other in a radial direction or an axial direction or a combination thereof. The driven coupler includes a lug arrangement rotatably mounted on a mounting member at the end of a driven shaft and having a pair of driven lugs on opposite sides of the driven shaft which are rotatable about an axis intersecting and normal to the axis of elongation of the driven shaft. A leaf spring coupled to the mounting member resiliently biases the lug arrangement into a neutral position in which the lugs extend outwardly in the direction of the axis of elongation of the driven shaft while at the same time permitting rotation of the driven lugs out of the neutral position in either of opposite directions against the resistance of the spring. The drive coupler employs a drive gear or other drive member in conjunction with a two-lug arrangement which may be rigidly mounted on the drive gear or which may be rotatable against spring resistance in a manner similar to the lug assembly of the driven coupler.

Planter row frame support

A transmission and drive assembly for a planter that can be transversely positioned on and selectively clamped on the planter frame at desired locations out of interfering relationship with the planting units. The transmission is at the end of the frame outside of the outermost planter unit but may be easily repositioned on the frame as is necessary. A ground wheel assembly is secured to so as to optionally extend to the front or rear of the frame. It may also be adjusted transversely to accommodate adjustments in the row spacings. The dual assembly includes a countershaft journaled on both the transmission and the wheel assembly bracket and driven by the ground wheel through ratchet assemblies. The transmission is also securable to the frame to extend either to the front or the rear thereof. A crossover drive assembly is provided for transferring drive from the front to the rear of the frame when the transmission is mounted to extend to the front of the frame. The arrangement of components facilitates transverse positioning of the transmission and drive assembly so that row spacings can be adjusted as desired.
