A working machine includes: a boom base portion including: an inner side wall; and an outer side wall disposed opposite to the inner side wall; a lift link disposed on a rear portion of the boom base portion; and a boom cylinder disposed in front of the lift link. One end side of the lift link is inserted between the inner side wall and the outer side wall and is pivotally supported on the boom base portion. The other end side of the lift link is pivotally supported on the machine body. One end of the boom cylinder is inserted between the inner side wall and the outer side wall in front of the lift link and is pivotally supported on the boom base portion. The other end of the boom cylinder is pivotally supported on the machine body by below the lift link.

An implement system includes a linkage and a bucket coupled with the linkage and movable between a dump position and a racked position. The bucket has a compound back section that forms a profile having a basin shape to assist in distributing material within the back section when the bucket is curled, and nesting the bucket close to the linkage. Related methodology is disclosed.

A vehicle includes a frame, an engine connected to the frame and operable to move the vehicle, an operator cab, a tool, and a boom arm. The boom arm includes a first linkage, a second linkage and a cylinder. The first linkage has a first portion connected to the frame and a second portion spaced from the frame. The second linkage has a first portion connected to the second portion of the first linkage and a second portion connected to the tool, the second linkage movable during boom operation within a first plane. The cylinder has a first portion connected to the first linkage and a second portion connected to the second linkage, such that the first linkage and the cylinder are movable during boom operation within a second plane. The first plane is offset from the second plane.

Spatial-temporal compression of sensing data from a plurality of sensors involves using a plurality of sensors to obtain measured physical data associated with a plurality of sensed elements. At each of a plurality of sampling times a set of N sampled data is acquired from the N sensed elements corresponding to the measured physical data. The sets of sampled data are analyzed to obtain statistical characteristic information. Thereafter, one or more frames of compressed data is generated using the statistical characteristic information to facilitate temporal and spatial data compression.

A four-bar assembly for a linkage assembly includes an arm pivot pin pivotally coupling a front arm with a rear arm of the linkage assembly. The arm pivot pin forms a first vertex of the four-bar assembly. A distal end of the front arm forms a second vertex of the four-bar assembly. The four-bar assembly includes a tilt cylinder having a first end and a second end. The first end of the tilt cylinder is pivotally coupled to a bracket angularly extending from the rear arm at a first end pin. The first end pin forms a third vertex of the four-bar assembly and the second end of the tilt cylinder forms a fourth vertex of the four-bar assembly respectively. An angle formed at the arm pivot pin and defined between the rear arm and the bracket lies between 0 and 90 degrees.

A compact utility loader compact utility loader comprising a frame, a first track and a second track positioned on either side of the frame, and a pair of loader arms. The loader arms are configured to couple with an attachment via a hitch plate and a hitch pin. The compact utility loader is configured such that as the loader arms are raised and lowered, the hitch pin follows a path approximately defined by a curve ?(x)=4.641e.sup.0.34x. The value x represents a horizontal direction and the function f(x) represents a vertical direction.

A compact utility loader is operated by a standing operator at the rear of a frame. A loader arm assembly comprises a scissors linkage on either side of the frame nesting around the prime mover. Each scissors linkage has an upper loader arm that is pivoted at its rear end to rears ends of a pair of lower loader arms such that the pivot connections to the upper loader arm move upwardly and forwardly relative to the frame during elevation of the loader arm assembly to provide a high lift capability. The frame is self-propelled by a differential drive and steering system that is operated by dual levers. A hand grip extends between and unifies the operation of the levers to permit the operator to more easily move the levers in the ways that are needed to provide either straight motion of the frame or turns of the frame.

A bucket level indicator mechanism for use with work machine with a front mounted loader implement includes a carriage assembly having a carriage frame comprising a carriage back and first and second carriage endplates at longitudinal ends of the carriage back, a first end of the carriage assembly being pivotably connected to one of the masts, wherein the carriage back has a slot formed therein along a portion of its longitudinal length. At least one guide rod extends between the carriage endplates. A boom height compensating link is mounted on the upper arm section. The boom height compensating link has at least one fixed traveler configured to be received in the slot in the carriage back, the carriage assembly being mounted so as to slide relative the traveler, wherein as the loader boom is raised and lowered by extension or retraction of the lift actuator, the carriage assembly rotates relative the mast about a pivot as the traveler slides in the slot in the carriage back. A twisted strip extends between the carriage endplates supported by the carriage assembly configured to rotate relative the carriage endplates. A sliding indicator nut rides on the at least one guide rod such that the sliding indicator nut may move along the longitudinal axis of the carriage assembly but is prevented from rotating relative the carriage assembly, wherein the indicator nut has a center aperture that receives the twisted strip and permits longitudinal movement of the nut relative the twisted strip along an axis A of the carriage assembly, but prevents angular movement of the portion of the twisted strip that engages the nut relative to the nut, wherein the nut is driven along the axis A of the carriage assembly by a linkage that is connected relative the bucket such that the nut reflects the level position of the bucket.

In one aspect, an implement adjustment assembly may include a lift arm pivotably coupled to a frame of a work vehicle at a first pivot joint and a bell crank pivotably coupled to the lift arm. Furthermore, the implement adjustment assembly may include a first actuator pivotably coupled to the frame of the work vehicle at a second pivot joint, with the first actuator further being pivotably coupled to the bell crank. The second pivot joint may be spaced apart from the first pivot joint by a first distance along a vertical direction of the work vehicle and by a second distance along a longitudinal direction of the work vehicle, with the first distance being at least one and half times greater than the second distance.
