A working vehicle includes a cabin. the cabin, which covers a steering seat disposed on a travelling machine body, includes a cabin frame constituting a framework of the cabin, and a roof assembly disposed on the upper end side of the cabin frame. A tailpipe is disposed on one side among a left side and a right side of the travelling machine body. Exhaust gas from an engine, mounted on the travelling machine body, is discharged to the outside through the tailpipe. The roof assembly is partitioned into a front-side chamber and a rear-side chamber, and an air conditioner is contained in a rear-side chamber side. An external-air intake opening is formed on one side opposite the tailpipe among a left side and a right side of the roof assembly.

A utility vehicle includes a plurality of ground engaging members and a frame supported by the plurality of ground engaging members. The frame assembly extends generally along a longitudinal axis of the utility vehicle. The utility vehicle further includes a front seating section coupled to the frame. The front seating section is configured to support an operator and a first passenger. Additionally, the utility vehicle includes a rear seating section coupled to the frame. The rear seating section is configured to support a second passenger and a third passenger. The rear seating section has an angled panel configured as a dead pedal for the second and third passengers, and a portion of the rear seating section extends forwardly into the front seating section.

A self-propelled trailer is provided and includes a frame, a pair of rear drive wheels, a steerable wheel, a drive system, a platform, and a lifting device. The pair of rear drive wheels are positioned under the frame along one end thereof, while the steerable wheel is positioned under the frame along an opposite end thereof with respect to the pair of rear drive wheels. The drive system includes a power system connected to the pair of rear drive wheels and a control system connected to the steerable wheel. The platform is positioned above the frame, while the lifting device is positioned between the steerable wheels and the pair of rear wheels. The platform includes a crane extending upward from the frame.

A protected tread widening system for a self-propelled high clearance sprayer. The system includes a frame with side rails and a first cross member and a second cross member extending between the opposite side rails, with the cross members being substantially hollow. Each of the cross members form slider receivers. The system also includes axle slider assemblies that are telescopically inserted into the slider receivers. Additionally, actuators are mounted within the cross members. These actuators are secured to the frame and to the axle slider assemblies to allow for telescopic movement of the axle slider assemblies into and out of the cross members. The actuators run substantially through a central axis of the first cross member and a central axis of the second cross member. This minimizes the bending moment of each actuator. Additionally, this system isolates the actuators from materials outside of the cross members.

A work vehicle includes a hood, an engine, a radiator, an air cleaner, and a condenser. The hood covers an engine compartment located on a front portion of a traveling body. The engine is a drive source. The radiator supplies a coolant to the engine. The air cleaner takes in outside air and supplies the air to the engine. The condenser cools a refrigerant. In front of the radiator, the air cleaner and the condenser are disposed one above the other. The condenser is withdrawable in the left and right direction.

A chassis frame includes side rails and cross-members that intersect at a number of intersection points, which collectively define a chassis frame with front and rear portions that define a main support section and an integral engine support section. Each side rail includes a top plate, a bottom plate, and first and second side plates extending between the top and bottom plates. The first and second side plates each have a first end coupled to a bottom surface of the top plate and a second end coupled to the top surface of the bottom plate. Each cross-member includes a top plate, a bottom plate, and first and second side plates extending between the top plate and bottom plates. The first and second side plates each have a first end coupled to a bottom surface of the top plate and a second end coupled to the top surface of the bottom plate. A plurality of gusset portions is formed between the top plates of the side rails and cross-members at each intersection point.

A chassis frame for an agricultural sprayer includes a top plate, a bottom plate spaced apart from the top plate, and a plurality of side plates extending from the top plate to the bottom plate. The top plate has a first thickness at a first location of the chassis frame to provide additional strength to the chassis frame at the first location. The top plate has a second thickness at a second location of the chassis frame to provide additional strength to the chassis frame at the second location.

A chassis frame including a first section and a second section. The first section includes a top plate having a first thickness, a bottom plate, and a plurality of side plates extending from the top plate to the bottom plate. The second section includes a top plate having a second thickness, a bottom plate, and a plurality of side plates extending from the top plate to the bottom plate. The first section and the second section are joined at least one transition joint. Each transition joint includes a protrusion configured to engage a pocket. Each pocket is defined by angular edges of the top and bottom plates of the first section. Each protrusion defined by angular edges of the top and bottom plates of the second section.

A vehicle frame having a calibrated frame stiffness gradient is provided by fixedly attaching a series of cladding plates to an external surface of a tubular member of the frame, with the series of cladding plates including at least one immediately preceding cladding plate and one successive cladding plate. The cladding plates have thicknesses and peripheral shapes that are cooperatively configured to provide the desired stiffness gradient in the frame member. A trailing raised bead extending from the last cladding plate in the series along the surface of the frame member provides a further means for achieving the desired stiffness gradient.

A large mobile crane including an undercarriage. The undercarriage includes a middle section between tracks, wherein a distance between the tracks can be increased or decreased by the insertion or removal of expansion parts. The two tracks are connected on opposite sides of the undercarriage to permit movement of the large mobile crane. The undercarriage also includes a drive unit, a superstructure, one or more control stations, at least two main booms, at least one derrick boom, and at least two lifting devices and counterweights. The counterweights are either arranged separately of or mounted on the undercarriage. The large mobile crane further includes a circular track, and support rollers attached to the superstructure, wherein the support rollers ride on the circular track, and wherein the circular track is an integral part of the expansion parts.
