Filed:

Apr 23, 1979

Appl. No.:

6/032281

Inventors:

Benjamin A. Shader - Golden CO
Bruce H. Mayeda - Longmont CO

Assignee:

The Eversman Mfg. Company - Denver CO

International Classification:

E02F 376

US Classification:

172779

Abstract:

Land leveling apparatus includes a leveling attachment drawn by a tractor with the attachment having pivotally connected side blade sections on a central blade section affording a substantially greater leveling capacity. The side blade sections fold up to reduce width during transport and have a power-driven linkage arrangement for each blade section that moves and positions the blade sections and locks them in the lowered working position, together with upper and lower level adjustments for the side blade sections. A hitch assembly facilitates quick coupling to a crossbar carried by the lower links of the tractor linkage and is pivotally joined to the central blade section so as to facilitate rear tractor wheel movement independently of the scraper blades. A leveling frame is connected at the front end to the central blade section and the pivotal attachments of the hitch assembly to the tractor linkage with the central blade section provide a four-bar linkage leveling structure that automatically moves in response to tractor movement to maintain the scraping edge substantially in a ground plane of the rear leveler frame wheels and front wheels of the tractor independently of the vertical movement of the rear wheels of the tractor.

Abstract:

An agricultural tool assembly (21) disclosed is used with a planter attachment. Assembly (21) includes a rotary disk (23) mounted on a lower end of a rotary spindle (25). An offset mount for the spindle includes a shank (41) adapted to be received in the vertical slot of a clamp (22) and a sleeve (45) offset from the shank for rotatably supporting the spindle. The sleeve is connected to the shank, using a bifurcated portion comprised of spaced plates (47, 48) connected to the sleeve with a lower pivot member (52) and an upper fastener (58) extending through arcuate slots (61 and 62) in the space plates. The planter attachment has a support frame that disposes the tool assembly (21) ahead of the planter (230) to cut the old crop prior to having the planter deposit the seed.

Abstract:

An agricultural tool assembly (21) disclosed is usable on a variety of implements in place of shovels, blades, tines or sweeps and on novel cultivating or crop root undercutting implements and the like. Assembly (21) includes a rotary disk (23) mounted on a lower end of a rotary spindle (25). An offset mount for the spindle includes a shank (41) adapted to be received in the vertical slot of a clamp (22) and a sleeve (45) offset from the shank for rotatably supporting the spindle. The sleeve is connected to the shank, using a bifurcated portion comprised of spaced plates (47, 48) connected to the sleeve with a lower pivot member (52) and an upper fastener (58) extending through arcuate slots (61 and 62) in the spaced plates. The disk may be tilted at a selected angle or set horizontally and for some applications may be set to release in the event the blade strikes an obstruction. A cultivator implement has front and rear disk gangs (108, 109, 114, 115) and a rear centered tool assembly (21).

Abstract:

An agricultural tool assembly includes a rotary disk mounted on a lower end of a rotary spindle. A mount for the spindle includes a shank adapted to be received in the vertical slot of a clamp and a sleeve for rotatably supporting the spindle. The sleeve is connected to the shank by spaced side plates connected to the sleeve with a lower pivot member and an upper fastener extending through arcuate slots in the spaced plates. A cultivator implement has front and rear disk gangs and a rear centered tool assembly. An onion undercutting implement has a front tool bar with front tool assemblies clamped thereto and a rear tool bar with rear tool assemblies clamped thereto. A tool assembly for material distribution has a spindle with a through hole, a swivel fitting at the inlet and a flared section at the outlet. Crop cutting and windrowing apparatus has pairs of tool assemblies tilted in and down toward the crop row and forwardly and down. Apparatus is provided to maintain the disks at a substantially constant depth.

International Classification:

F16B 218
F16B 704
A01B 6304

US Classification:

403374

Abstract:

A clamping device for exerting clamping forces in two directions to a shank between a pair of spaced clamping members having a transverse stop. The device includes an elongated bolt like body having a pair of axially spaced sections, a head at one end and external threads on an opposite end portion with a nut on the threads for applying a first clamping force to the spaced members. An eccentric section between the shaft sections applies a transverse clamping force to the shank. A pair of flat plates forming the clamping members has two spaced clamping devices and is arranged to slidably clamp to a variety of movable supports. A pair of spaced clamping plates are affixed to the end of a longitudinal frame with the option of a shim to accomodate shanks of smaller sizes.
