A vehicle chassis arrangement, preferably for use in an agricultural tractor. The chassis has two frame elements and a differential housing, where the ends of the frame elements are connected to the side of the differential housing facing the rear of the vehicle. A tank cover is attached adjacent to that side of the differential housing, to define a fluid storage tank between the tank cover and the surface of the differential housing.

A utility vehicle comprises a plurality of ground engaging members and a frame supported by the plurality of ground engaging members. The frame includes a front frame portion, a mid-frame portion, and a rear frame portion. The utility vehicle further comprises an attachment supported at the front frame portion. Additionally, the utility vehicle includes an operator area supported by the frame and including an operator seat and an adjacent passenger seat spaced apart from the operator seat. The operator seat and the passenger seat are in a side-by-side arrangement. The utility vehicle also comprises an auxiliary power assembly having an attachment shaft configured to be operably coupled to the attachment. The attachment shaft extends in a generally longitudinal direction of the utility vehicle and projects outwardly from the front frame portion.

A vehicle or machine suitable for operation on uneven or inclined surfaces, such as a forest work unit, comprises at least three frame parts and two rotational planes. Each frame part has rotational planes, in each particular case, on an interface between two successive frame parts of the vehicle or machine. The rotational planes are, in each particular case, planes perpendicular to the longitudinal axis of the vehicle or machine in the neutral position. The frame parts are thus arranged to be independently rotatable in relation to the rotational plane.

A frame apparatus for agricultural vehicles includes an engine frame configured to support an engine of an agricultural vehicle; and at least one of a front frame and a rear frame connected to each of a working machine and the engine frame to support the working machine is mounted in the agricultural vehicle, wherein at least one of the front frame and the rear frame is detachably connected to the engine frame.

A frame apparatus for agricultural vehicles includes an engine frame configured to support an engine of an agricultural vehicle; and at least one of a front frame and a rear frame connected to each of a working machine and the engine frame to support the working machine is mounted in the agricultural vehicle, wherein at least one of the front frame and the rear frame is detachably connected to the engine frame.

A working vehicle includes: an engine mounted on a traveling machine body; a hydraulic continuously variable transmission configured to shift driving force from the engine; a transmission case incorporating the hydraulic continuously variable transmission; and rear traveling units disposed on both left and right sides of the transmission case via rear axle cases. The transmission case is divided into three sections of a front case, an intermediate case, and a rear case. The left and right rear axle cases are attached to both left and right sides of the rear case. The intermediate case, coupling the front case to the rear case, is coupled to left and right vehicle body frames forming the traveling machine body.

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 tracked vehicle with a chassis comprising an upper frame structure connected to a lower frame structure, the lower frame structure spanning a longitudinal distance along a longitudinal direction of the vehicle, wherein over a first portion of the longitudinal distance, the lower frame structure overlaps with the upper frame structure and wherein over a second portion of the longitudinal distance, the lower frame structure does not overlap with the upper frame structure. The tracked vehicle may also comprise an operator cabin, power plant mounted to the upper frame structure and a plurality of track assemblies for traction of the tracked vehicle. Each track assembly is mounted to the lower frame structure of the chassis and comprises a drive wheel; an end wheel; and a plurality of support wheels therebetween; and an endless track disposed around the plurality of wheels for engaging a ground on which the tracked vehicle travels.

A rear axle case of an agricultural work vehicle and a rear axle assembly including the same. The rear axle case of an agricultural work vehicle includes: a rear axle cover, having a hollow pipe shape, for surrounding a rear axle; a reduction gear cover unitarily provided at the side of the rear axle cover; a differential axle cover integrally formed at the front end of the reduction gear cover so as to cover a differential axle extending to the outside of a rear differential case; and a brake unit cover unitarily provided at an opening of the differential axle cover in a form in which one side opening of the differential axle cover is covered, such that a space in which a multi-disk brake unit can be provided is formed between the brake unit cover and the rear differential case.

A rocker bogie includes a first base which including a first wheel, a second wheel, and a third wheel each of which is configured to be in contact with a first flat surface, a second base including a fourth wheel which is configured to be in contact with the first flat surface, and a rotary shaft connecting the first base and the second base to each other such that the second base is rotatable with respect to the first base. The rotary shaft is parallel to a first straight line which connects a rotation center of the first wheel and a rotation center of the second wheel to each other and is disposed between a rotation center of the third wheel and the first straight line, and the fourth wheel is disposed at an opposite position to the third wheel across the first straight line.
