Compact tool carriers having a loader mounted to a low-profile mainframe are disclosed. In some embodiments, the pivot points of the mainframe about which the loader is pivoted are low relative to the mainframe to reduce the mainframe size.

A front loader includes a boom, a main frame attached to a vehicle body, a sub frame supporting the boom and being detachably attached to the main frame. The front loader includes a receiving tool provided on the main frame a cylindrical shaft provided on the sub frame and configured to be engaged with the receiving tool when attaching the sub frame to the main frame, a protruding portion protruding from the main frame and configured to guide the cylindrical shaft to be engaged with the receiving tool, and a coupling plate provided on the sub frame, the coupling plate having an opening through which the protruding portion is inserted when the cylindrical shaft is engaged with the receiving tool. The protruding portion protrudes forward from the main frame in a front-rear direction of the vehicle body.

A compact utility loader compact utility loader comprising a frame including a lower portion and an upper portion. A width of the lower portion is smaller than a width of the upper portion. The compact utility loader additionally comprises a first track and a second track, with each track being positioned on a side of the frame. Each of the tracks has a width of at least 7.5 inches, and the compact utility loader has an overall width of no more than 36 inches.

Mainframes for a self-propelled machine are disclosed. The mainframe includes first and second pockets that extend from the front end to the rear end of the mainframe. A hydraulic reservoir housing extends from the first side to the second side of the mainframe. The hydraulic reservoir housing is disposed between the front end of the mainframe and first and second drive openings.

A method of extending a reach of a material mover may include uncoupling and removing a first linkage that couples a work implement to an actuator on the material mover; uncoupling the work implement from one or more lifter arms; securing one or more extensions to each of the one or more lifter arms by (a) fastening, with a first fastener, an extension to a corresponding lifter arm, though a lifter-arm retention aperture, and (b) further securing the extension to the corresponding lifter arm with one or more additional fasteners adjacent the lifter-arm retention aperture and a top edge or bottom edge of an end of the corresponding lifter arm; coupling the work implement to the one or more extensions; and coupling a second linkage, which is longer than the first linkage, to the work implement and to the actuator.

A work machine (1.1, 1.2, 1.3) having precisely one main vehicle axle (3), wheel elements (4.1, 4.2) arranged on the main vehicle axle (3) on both sides, and a working unit (2) or a holder (9) for a working unit. The working unit (2) is arranged on a vehicle frame (12) by means of at least one pivot arm (6, 6.1, 6.2) with at least one rotatably mounted working arm (7, 7.1, 7.2). The work machine (1.1, 1.2, 1.3) also includes at least one displaceable weight (5, 5.1, 5,2), which is arranged on the vehicle frame (12) by means of at least one rod system (11, 11.1, 11.2), wherein an exclusive movement channel (16.1, 16.2, 16.3, 16.4, 16.5, 16.6, 16.7, 16.8, 16.9, 16.10) along the vehicle longitudinal axis (14) is assigned to each of the displaceable weight(s) (5, 5.1, 5.2), the rod system(s) (11, 11.1, 11.2) and the pivot arms (6, 6.1, 6.2) with the working arms (7, 7.1, 7.2).

A lift arm structure for a power machine with a frame can include a multi-bar linkage that is pivotally secured to the frame and a leveling link that is pivotally secured to the multi-bar linkage. The leveling link can be configured to transmit force from the leveling link to an implement as the multi-bar linkage is actuated to raise or lower the implement, including via a multi joint member that is pivotally secured to the leveling link, the multi-bar linkage, and an actuator that is configured to move the implement.

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 method of extending a reach of a material mover may include uncoupling and removing a first linkage that couples a work implement to an actuator on the material mover; uncoupling the work implement from one or more lifter arms; securing one or more extensions to each of the one or more lifter arms by (a) fastening, with a first fastener, an extension to a corresponding lifter arm, though a lifter-arm retention aperture, and (b) further securing the extension to the corresponding lifter arm with one or more additional fasteners adjacent the lifter-arm retention aperture and a top edge or bottom edge of an end of the corresponding lifter arm; coupling the work implement to the one or more extensions; and coupling a second linkage, which is longer than the first linkage, to the work implement and to the actuator.

A sensor-augmented system for optimizing the loading parameters of a work machine to engage a pile. The system comprises a sensor coupled with the work machine where the sensor is configured to collect image data of the pile in a field of view of the sensor; a sensor processing unit communicatively coupled with the sensor where the sensor processing unit is configured to calculate a volume estimation of the pile based on the image data; and a vehicle control unit communicatively coupled with the sensor processing unit to modify a loading parameter of the work machine in response to a calculated predictive load based on the volume estimation and stored data to identify material type of the pile.
