摘要:
An improved hydraulic circuit for raising and lowering a three-point hitch-mounted implement having a lift assist assembly and for selectively lowering the lower draft links of the three-point hitch to transfer implement weight to the rear wheels of the tractor without affecting the normal operation of the tractor operator control valve. A shuttle valve connects the rockshaft control valve, which otherwise would be disabled, to the rockshaft cylinder which controls the lower draft links. The ball-check valve also connects the rockshaft cylinder to the operator control valve while isolating the rockshaft control valve from the operator control valve.

A crop sheild is connected to the aft ends of a pair of parallel links by a bracket assembly which can pivot to permit the shield to dump trash. The bracket assembly is pivotally connected to the aft end of the lower link and includes a slot slidably received on a pin located on the aft end of the upper link to maintain the links in a generally parallel relationship. The weight of the shield normally biases the shield to a horizontal field-working position with the end of the slot stopped against the pin. When trash builds up, the shield pivots with respect to the lower link and the slot slides over the pin as the shield moves up against the bias over the trash. Dump forces are reduced since the shields pivot independently of the parallel links.

A soil-smoothing or leveling tool, such as a harrow or press wheel gang, is rockably connected to the rear of the main frame of a tillage or seeding implement. The tool frame width is substantial compared to the width of the implement, and the height of the tool frame relative to the main frame is sensed to provide an accurate indication of the average depth of penetration across the width of the implement. The angle-sensing device operably connected to the drawbar of the trailing tool senses the angle between the main frame and the drawbar, and a control valve assembly responsive to the sensed angle controls the main frame lift system to maintain a preselected relationship between the tool and the main frame and thereby accurately control tillage or planting depth.

A table may be sized and configured to nest with another table to reduce a height of a plurality of stacked tables in a nested configuration. The table may include a table top with a receiving portion disposed at least proximate an intersection of an upper surface and a sidewall. The table top may also include a lip and a lower portion of the lip may include a contact surface that is sized and configured to contact an upper surface of an adjacent, nested table. The lower portion of the lip may also include an engaging portion that is sized and configured to be disposed in a receiving portion of an adjacent, nested table. The contact surface and the engaging portion may be directly adjacent to each other in the lower portion of the lip.

A table may be sized and configured to nest with an adjacent table to reduce a height of a plurality of stacked tables in a nested configuration. The table may include a molded plastic table top that has a receiving portion disposed proximate an outer perimeter of the table top. The receiving portion is sized and configured to receive an engaging portion of an adjacent, nested table. The table may also include a frame with a first load bearing surface sized and configured to contact a generally planar upper surface of another adjacent, nested table. The table may further include an engaging portion sized and configured to be disposed in a receiving portion of the adjacent, nested table. The nested tables are preferably substantially identical and aligned in the stacked configuration.

A table and chair set may include a table, a plurality of chairs and a storage case. The table may include a folding table top that has a footprint in the folded position. The chairs may be folding chairs that have a footprint generally equal to or slightly smaller than the footprint of the table in the folded position. The case may include an interior cavity that is sized and configured to receive at least a portion of the table and the chair in the folded positions, the cavity having a size generally equal to or slightly larger than the footprint of the folding table and the folding chair in the folded positions.

A foldable table may include a table top and legs that are movable between an extended position and a collapsed position. The table top may include a first section and a second section that are movable between folded and unfolded positions. A first portion of a side rail may be connected to the first section of the table top and a second portion of the side rail connected to the second section of the table top. A hinge assembly may connect the first and second portions of the side rail in an offset configuration. When the table is in the folded position, an inner surface of the first portion of the side rail may be disposed at least proximate an outer surface of the second portion of the side rail.

A modular enclosure may include a number of components, such as floor panels, wall panels and roof panels, which may be interconnected to form a structure such as a shed. For example, the shed may include wall panels with connecting portions that are sized and configured to allow adjacent wall panels to be interconnected. The wall panels may also include outwardly extending projections that allow the wall panels to be connected to the floor panels. In addition, the wall panels may include receiving portions that may receive portions of the roof panels, such as an outwardly extending lip. Advantageously, a truss may extend through the receiving portions in the wall panels and the truss may include a channel that is sized and configured to allow any water that enters the shed through a roof panel seam to be removed from the shed.
摘要:
A modular enclosure, such as a shed, may include a number of components. For example, the enclosure may include roof panels, floor panels and wall panels that are connected to the roof and/or floor panels. Preferably, the wall panels span the seams disposed between the roof and/or floor panels. In addition, the wall panels are preferably offset from the roof and/or floor panels. Further, the roof panels, wall panels and floor panels desirably have a substantially similar width. The enclosure may also include one or more corner panels and the corner panels may have a living hinge that generally divides the corner panel in half. Advantageously, the offset connection of the roof panels, wall panels and floor panels may facilitate construction of an enclosure with increased strength and functionality.
