The adjustable track-width system may include a first axle member having a top section and a bottom section and a second axle member having a top section and a bottom section, where the second axle member is receivable by the first axle member and movable between a first position and a second position relative to the first axle member. The adjustable track-width system may further include two or more shims that determine a clearance between the first axle member and the second axle member at the first and second positions, where at least a portion of a first shim may be between the top section of the first axle member and the top section of the second axle member and at least a portion of a second shim may be between the bottom section of the first axle member and the bottom section of the second axle member.

Adjustable track-width systems for agricultural machines

A ladder for an agricultural vehicle may comprises a first frame member and a second frame member. Each frame member may have an upper portion and a lower portion. At least one foot support body may be operably connected to each of the frame members. The upper portion of each frame member may be operably connected to a frame of the agricultural vehicle. The frame of the agricultural vehicle may comprise a fore and an aft. The ladder may comprise a deployed position and an angled stowed position. The angled stowed position may comprise the first frame member and the second frame member being upward and rearward towards the aft of the agricultural vehicle frame.

An agricultural vehicle suspension may comprise a spring and a first spindle operably coupled with the spring in a spindle axial direction. A stop body may be operably coupled to the first spindle in a cylinder axial direction. The stop body may be configured to limit an axial length of travel of the suspension relative to the first spindle. The first spindle may be a steering spindle or a suspension spindle.

An independent strut suspension utilizes upright twin spindles and a spindle cap linked to the spindles that translates vertically along the spindles as the suspension moves over uneven terrain. An upright strut shaft is mounted in a strut journal for axial and rotational movement with respect to the journal. A steering arm is connected for rotation about the strut shaft axis, and the strut shaft moves axially with respect to the steering arm as the frame moves over the uneven terrain. The upright spindles connect the steering arm and the upper mount, and a spring is supported between the upper end of the strut shaft and the upper mount and provides cushioning for the wheel support as the strut shaft moves axially in the journal.

High clearance vehicle suspension with twin spindles for transferring steering torque

Foldable boom inner wings are attached to a boom center frame through a rocker attached to a breakaway hydraulic cylinder pressurized to full stroke and connected to an accumulator. When a wing impacts an object, the impact load is transmitted through the fold cylinder and rocker into the breakaway cylinder. As the breakaway cylinder retracts to allow the wing to pivot, pressure builds in the system in three stages. First pressure builds along an accumulator pressure curve until a relief valve in the hydraulic system actives to initiate the second stage wherein oil is dumped through the relief valve. Thereafter, pressure is again allowed to build along the same accumulator curve to absorb impact hydraulically before the cylinder reaches full stroke. The staged pressure buildup prevents boom momentum from gaining and loads from increasing above the strength of the overall structure.

Agricultural boom section

An easily manufactured large boom construction includes a plurality of main tube support sections fabricated from plate material of differing material thickness, grade and section dependent on load. The tube support sections include apertured areas which provide a preliminary snap-fit of the main tubes to significantly reduce need for additional fixturing. The opposite ends of diagonal tubes pass through apertures in the fabricated support sections for accurate tube location without complicated weld fixtures or precise tube length and cut end angle tolerances. The tubes are welded on opposite sides of the sections to eliminate need for tube-to-tube connections or connections wherein a cut end edge has to be precisely placed against a planar surface. An inverted right triangle boom cross section with wing over-top fold configuration ability provides strength, stiffness and infinite nozzle placement possibilities.
