A power hoist equipment crane system to be used with a tractor roll bar, the system including a pivotable support bar configured to be substantially U-shaped having two side portions and a middle portion connecting the two side portions, a cable support member provided to the pivotable support bar and configured to support a cable from a hoist, and bracket assemblies provided respectively proximate each end of the pivotable support bar and configured to couple the pivotable support bar to the tractor roll bar in a pivoting arrangement, the bracket assemblies configured such that the pivotable support bar is pivotable between a substantially vertical stowed position when not in use, and a substantially horizontal use position in which the cable support member is positioned at a point spaced back from the tractor so as to be located over an implement that is attachable to the tractor.

An implement attachment adapter, including a centrally located top clevis; two spaced apart lower clevises located below the centrally located top clevis and on opposing sides of a line extending vertically through the top clevis. The two spaced apart lower clevises being are recessed into or behind a first face of a flat plate. The flat plate further includes side tabs located proximate each horizontal peripheral edge thereof extending outwardly away from the first face of the plate. A bottom tab extends outwardly downwardly away from the first face at an obtuse angle relative to the plate. A top bar extends across proximate a top portion of the plate and outwardly away from the first face of the plate and is oriented at an acute angle to the plate. The plate further presents engagement apertures and a second face opposing the first face to which the implement may be coupled.

An implement operating apparatus has a U-shaped drive frame supported on drive wheels, each pivotally mounted about a vertical wheel pivot axis. A steering control selectively pivots each drive wheel. A power source is connected through a drive control to rotate the drive wheels in either direction. First and second implements are configured to perform implement operations and to rest on the ground and when the drive frame is maneuvered to an implement loading position with respect to each implement, the implement is connectable to the drive frame and movable to an operating position supported by the drive frame. When the implement is in the operating position, the steering and drive controls are operative to move and steer the drive frame and implement along a first travel path or a second travel path oriented generally perpendicular to the first travel path.

A method for determining a physical parameter of an adjustable upper link of a three-point hitch during a working operation thereof includes providing a lower link of the three-point hitch and an implement attachable to the upper and lower links of the three-point hitch. The method includes generating calibration data prior to the working operation of the three-point hitch, where the calibration data defines a relationship of a length of the upper link to an upper link angle defined between the upper link and a reference line. Moreover, the calibration data is used to determine a physical parameter of the adjustable upper link during the working operation.

Skid-steer type power unit engageable with an implement using an attachment assembly including an attachment frame and a hitch. An arcuate frame member is located forwardly of the attachment frame and is engaged therewith in such a way that the frame member pivots about a vertical axis located forwardly of the frame member and generally centrally positioned relative to the attachment frame. The frame member pivots in response to actuation of a hydraulic cylinder. The power unit includes a system for transferring weight of the implement rearwardly onto the power unit. A belt-drive power-take off system on the power unit powers the implement's operation. An underbelly drop spreader is located between the front and rear wheels of the power unit and a brine delivery system distributes brine from nozzles located rearwardly of the rear wheels. A unique control panel permits operation of all systems on the power unit and implement.

A work vehicle includes a first ground-engaging implement and a second ground-engaging implement connected to a chassis. The first ground-engaging implement moves within a first movement envelope with respect to the chassis, and the second ground-engaging implement moves within a second movement envelope with respect to the chassis. A lift arm is connected to the chassis and positioned between the first and second ground-engaging implements. The lift arm moves along a range of movement between a raised position and a lowered position. The lift arm is entirely positioned outside both of the first movement envelope and the second movement envelope within the entire range of movement between the raised position and the lowered position, such that the lift arm is permitted to move along the entire range of movement between the raised position and the lowered position without abutting the first movement envelope or the second movement envelope.

A work vehicle includes a lifting mechanism to control at least one of a height and a posture of a work machine connected to the work vehicle. The lifting mechanism is able to control at least one of the height and the posture by using a hydraulic drive. The work vehicle includes an oil-temperature acquirer to acquire an oil temperature to be used for the hydraulic drive, a maximum oil amount setter to set a maximum oil amount according to the oil temperature acquired by the oil-temperature acquirer, the maximum oil amount being a maximum value of a supply amount of oil used to drive the hydraulic drive, and a hydraulic drive controller to control the hydraulic drive below the maximum oil amount set by the maximum oil amount setter.

A walk-behind tractor has an increased ground clearance to define a plant receiving space that has a greater height than a conventional walk-behind tractor having a straight axle. The walk-behind tractor has trailing drop arms from a frame that carry wheel axles that result in an elevated height of a driveshaft. The elevated driveshaft increases the ground clearance for taller plants to pass therebeneath during operation of the walk-behind tractor which would otherwise be too tall to pass below a conventional straight axle walk-behind tractor.
