A ripper assembly for a machine includes a primary carriage, a secondary carriage pivotally coupled to the primary carriage. The primary carriage is formed from a winged support structure having a pair of opposing sides and a pair of pivot arms welded onto corresponding opposing sides of the winged support structure. The secondary carriage includes a mid-portion and a pair of intermediary portions welded to ends of the mid-portion to form a single ripper mounting assembly. Additionally, or optionally, the secondary carriage could include a pair of end portions that could be welded onto distal ends of the intermediary portions for forming the ripper assembly to a multiple ripper mounting configuration.

An interlock system for a work vehicle includes a controller configured to output instructions to a first actuator assembly to control a first implement positioned rearward of a chassis of the work vehicle. The controller is configured to instruct the first actuator assembly to block movement of the first implement while an access door of the chassis is in an open state, in which the access door is positioned on a rear portion of the chassis, longitudinally opposite a cab ingress/egress door positioned proximate to a forward portion of the chassis, and the controller is configured to output instructions to a second actuator assembly to control a second implement positioned forward of the chassis.

A system for moving material with a work implement includes an image display device, an operator input device, and a position sensor. A controller is configured to determine a position of a work surface at a work site, display a portion of the work site on the image display device including an operational location at the work area, modify a position of the operational location on the image display device with the operator input device to define a modified operational location, generate a material movement plan based upon the position of the work surface and modified operational location, and generate command instructions to move the machine according to the material movement plan.

An accessory mounting system for a work vehicle includes a first mount extending from a lateral side of a body of the work vehicle, in which the first mount is configured to couple to a first end of a rotatable component to rotatably couple the rotatable component to the body of the work vehicle. Further, the accessory mounting system for includes a cover assembly having a cover, in which the cover assembly is coupled to the lateral side of the body of the work vehicle, and at least a portion of the cover is positioned laterally outward from the first mount such that the first end of the rotatable component is disposed between the lateral side of the body of the work vehicle and the portion of the cover while the first end of the rotatable component is coupled to the first mount.

A work vehicle includes a rotary member, a support member, a sealing ring, a pressure controller, and a vehicle speed determination component. The rotary member has a first hydraulic fluid supply channel to supply the hydraulic fluid to the steering clutch, and is rotated by power from the transmission when the steering clutch is engaged. The sealing ring is disposed between the rotary member and the support member and is mounted adjacent to the connected part between the first hydraulic fluid supply channel and the second hydraulic fluid supply channel. The pressure controller controls the engagement pressure to be a specific first pressure when the vehicle speed is determined not to be equal to or greater than a specific speed, and controls the engagement pressure to decrease from the first pressure when the vehicle speed is determined to be equal to or greater than a specific speed.

A rear frame for a motor grader includes a pair of arms that are disposed equidistantly from a mid-plane. Each arm has a front portion, a rear portion, and a mid-portion located between the front and rear portions. The front portion of each arm is configured to pivotally couple with a front frame of the motor grader. The rear frame also includes a ripper mounting arrangement, a bumper, and a torque resisting member. The ripper mounting arrangement is located at a rear end of the rear portion of each arm. The bumper is laterally disposed with respect to the mid-plane and rigidly attached to a position on the rear portion of each arm located adjacent the rear end of the rear portion of each arm. The torque resisting member is laterally disposed with respect to the mid-plane and rigidly attached to the mid-portion of each arm.

Work machines including automatic grading features and functions are disclosed. One exemplary embodiment is a work machine including a chassis, ground contacting members rotatably coupled with the chassis and an actuator coupled with the chassis. A pole assembly extends above the chassis. A receiver is coupled with the pole assembly and structured to detect a wireless signal. An electronic controller is in operative communication with the receiver and the actuator, the electronic controller structured to adjust an actuator in response to a wireless signal detected by the receiver. The actuator is adjustable to vary position of the receiver and to vary position of a grading tool assembly coupled with a suspension.

A work vehicle includes a vehicle body, a travel device, a driving source, and a cooling device. The travel device is provided below the vehicle body. The driving source is disposed in a front part of the vehicle body. The driving source generates driving power for the travel device. The cooling device is disposed on one side in the vehicle width direction of the vehicle body and rearward of the driving source.

A system for determining a lowest cost distal end dump location is provided. A controller determines an amount of material to be moved from the first work area to the second work area, and evaluates a plurality of potential distal end dump locations at the second work area to determine a cost associated with moving the material at the second work area to form each second work area material configuration and select a lowest cost distal end dump location corresponding to a lowest cost second work area material configuration.

A ripper assembly for a machine includes a primary carriage, a secondary carriage pivotally coupled to the primary carriage. The primary carriage is formed from a winged support structure having a pair of opposing sides and a pair of pivot arms welded onto corresponding opposing sides of the winged support structure. The secondary carriage includes a mid-portion and a pair of intermediary portions welded to ends of the mid-portion to form a single ripper mounting assembly. Additionally, or optionally, the secondary carriage could include a pair of end portions that could be welded onto distal ends of the intermediary portions for forming the ripper assembly to a multiple ripper mounting configuration.
