A dual mode control system for a work vehicle includes a hydraulic system configured to drive a loader assembly and a dozer assembly coupled to the work vehicle. The hydraulic system includes a fluid delivery system comprising a plurality of flow paths fluidly coupled to a hydraulic pump. The hydraulic system includes a valve assembly configured to regulate diversion of fluid into a first and a second hydraulic cylinders coupled to the fluid delivery system to adjust the loader assembly, or into a third cylinder coupled to the fluid delivery system to adjust the dozer assembly. The dual mode control system also includes a controller operably coupled to the valve assembly, and one or more user interfaces coupled to the controller to enable an operator to provide inputs to cause the controller to adjust the valve assembly, and to thereby adjust the loader assembly or the dozer assembly.

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.

An attachment assembly for attaching to a skid loader for operating at a rear of the skid loader is disclosed. The attachment assembly includes boot attachments for attaching to respective sides of the rear of the skid loader; side plates each attached to one of a respective of the boot attachments; and a quick attach plate attached to the side plates. The quick attach plate is configured for quick attachment to a skid loader accessory for performing a task at the rear of the skid loader.

A vehicular accessory system includes a first accessory pivotable in a first direction via pressurized fluid at a first actuator and pivotable in a second direction via pressurized fluid at a second actuator, and a second accessory pivotable in a third direction via pressurized fluid at a third actuator and pivotable in a fourth direction via pressurized fluid at a fourth actuator. A valve assembly is in fluid communication with the first, second, third and fourth actuators. Responsive to pivoting of the first accessory to a first fully pivoted orientation, the valve assembly automatically operates to supply pressurized fluid to the third actuator to pivot the second accessory in the third direction. Responsive to pivoting of the first accessory to a second fully pivoted orientation, the valve assembly automatically operates to supply pressurized fluid to the fourth actuator to pivot the second accessory in the fourth direction.

A retrieval arrangement for a ripper of a machine includes a bollard that is disposed towards a rear portion of the machine. The bollard includes a base that is disposed along a mid-plane of the ripper and connected to the ripper via a ripper carriage. A method for retrieving the ripper includes positioning a sling around the bollard, and pulling the sling using another machine such that the bollard is biased in the direction away from the ripper carriage.

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.

The present invention is directed to levelling apparatus, typically as used on tractors, excavators and skid-steer vehicles, and references the levelling assembly and mounting options including directly to the existing blade of vehicles as well as other mounting arrangements. Preferred embodiments of a levelling apparatus include a blade body portion and body mounting portion connected by an arrangement of fixed and adjustable linkages, preferably hydraulic, to allow movement of the blade body portion (relative to the body mounting portion) in substantially an up and down direction, as well as rotational movement about an axis perpendicular to the general plane of an attached blade.

Vehicles having a control console that may be moved between a plurality of locations relative to the body of the vehicle are disclosed. The control console may include a direction control device for controlling movement of the vehicle that is adaptive such that movement of the vehicle is based on both the direction at which the direction control device is actuated and the sensed position of the control console.

A ground engaging tool control system including a first sensor system, a second sensor system, a first actuator system, a second actuator system, and an electronic data processor. The first and second sensor systems detect respective positions of a first ground engaging tool and a second ground engaging tool. The first actuator system is coupled to the first ground engaging tool and the second actuator system is coupled to the second ground engaging tool. The electronic data processor determines a target grade profile and generates two or more control signals to adjust target positions of the first ground engaging tool and the second ground engaging tool. The target position of the second ground engaging tool is determined based on at least one of a position of the first ground engaging tool or the comparison of a current grade profile and a desired grade profile.

A work tool for a hammer is disclosed. The work tool may include a first terminal end having a planar surface, and a second terminal end opposite the first terminal end and including a tool tip. The work tool may further include a shank between the first and second terminal ends and including a proximal first shank portion and a distal second shank portion coaxially aligned. The work tool may further include a collar between the first and second shank portions. The collar may include a rectangular portion forming lateral sides of the collar, each of the lateral sides including a planar surface that extends in a direction along an axis of the work tool. The collar may further include a flange having a diameter greater than a diameter of the shank and greater than a length of a lateral side of the rectangular portion.
