An attachment system for a work vehicle implement includes an implement attachment assembly. The implement attachment assembly includes a support structure coupled to a receiver assembly. The support structure includes a first mounting feature configured to engage a first corresponding mounting feature extending downwardly from a bottom surface of a work vehicle, and a second mounting feature configured to engage a second corresponding mounting feature extending downwardly from the bottom surface of the work vehicle. The first and second mounting features of the support structure are spaced apart from one another along a longitudinal axis relative to a direction of travel of the work vehicle, and the first and second mounting features of the support structure are configured to substantially block horizontal and vertical movement of the support structure relative to the work vehicle via engagement with the first and second corresponding mounting features of the work vehicle.

A frame assembly for supporting an implement on a vehicle includes a support frame attachable to the vehicle, a lever pivotable on the support frame between a first and second positions, and a biasing assembly connecting the lever to the support frame. The implement is connectable to the lever via an implement support frame. The biasing assembly is movable between an extended position and a compressed position and is biased toward the extended position. The lever and the biasing assembly define an acute angle that opens toward the vehicle when the support frame is removably attached to the vehicle and the lever is in the first position.

An implement mounting assembly is mountable to a vehicle after having been positioned using a retractable cable. The implement mounting assembly has a frame defining a cable routing space, an attachment point to which the cable is attachable, and an auto-release cable management assembly including a hook, first and second underside guide surfaces for guiding the cable towards the hook as the cable retracts, and a gate. The gate is positioned with respect to the hook to be movable between open and closed positions in which the hook is accessible and inaccessible to the cable. The gate is biased towards the closed position. When a tension in the cable is above a threshold tension, the gate moves into the open position and the cable accesses the hook, and when the tension decreases to below the threshold tension, the gate moves towards the closed position releasing the cable from the hook.

A box blade earth grading implement incorporating a blade; a left wall having upper and lower segments, the lower segment having a lower end, and the upper segment being attached to the left end of the blade; a right wall having upper and lower segments, the lower segment having a lower end, and the upper segment being attached to the right end of the blade; left and right skid plates attached to the lower ends of the lower wall segments; left and right hydraulic cylinders having left and right upper mounts attaching to the walls' upper segments; left and right pivot mounts attaching the lower ends of the left and right hydraulic cylinders to the left and right skid plates; and a towing tongue extending forwardly from the blade.

A trunnion and socket assembly is provided. The trunnion and socket assembly includes a trunnion, a socket, and a retention assembly. The trunnion includes a first portion and a second portion, the second portion defining an outer diameter. The retention assembly includes at least two cap elements and a ring member. The cap elements are coupled in an abutting relationship with a first surface of the socket. The cap elements have a second surface and a third surface. The ring member is adapted to be coupled in an abutting relationship with the third surface of each of the cap elements. The ring member has a fourth surface and a fifth surface. The ring member defines an inner diameter that is greater than the outer diameter of the second portion of the trunnion.

An attachment system for a work vehicle implement includes an implement attachment assembly. The implement attachment assembly includes a support structure coupled to a receiver assembly. The support structure includes a first mounting feature configured to engage a first corresponding mounting feature extending downwardly from a bottom surface of a work vehicle, and a second mounting feature configured to engage a second corresponding mounting feature extending downwardly from the bottom surface of the work vehicle. The first and second mounting features of the support structure are spaced apart from one another along a longitudinal axis relative to a direction of travel of the work vehicle, and the first and second mounting features of the support structure are configured to substantially block horizontal and vertical movement of the support structure relative to the work vehicle via engagement with the first and second corresponding mounting features of the work vehicle.

A work vehicle comprising a frame supported by a ground engaging device. A boom assembly is coupled to the frame. An attachment coupler is coupled to the boom assembly. An electronic data processor is communicatively coupled to a boom actuator, an attachment coupler actuator, a boom sensor, an attachment coupler sensor, and an operator input device. A computer readable storage medium comprising machine readable instructions that, when executed by the processor, cause the processor to receive an operator input and for a tilt forward command, command the boom actuator to move the boom assembly to a frame contact position and then command the attachment coupler actuator to move the attachment coupler towards a lower position. For a tilt rearward command, command the attachment coupler actuator to move the attachment coupler towards an upper position and then command the boom actuator to move the boom assembly towards a raised position.

A movable blade assembly which can be attached to the front or rear of a vehicle and the height of the blade can be adjusted with respect to a roadway such that the blade only comes into contact with relatively large debris and moves them from the roadway.

A method of selecting an economy operating mode of a work machine includes detecting a current throttle position of a throttle control and a current track speed with a speed sensor, and determining a current drivetrain load of the machine as a function of motor torque, a drivetrain ratio, a drivetrain mechanical efficiency, a final drive windage factor, and a rolling radius. The method includes decreasing the current throttle command if a ratio of the current drivetrain load to an available drivetrain load is less than a load threshold. A transmission ratio of the transmission is increased by the controller to an increased transmission ratio if the ratio of the current drivetrain load to the available drivetrain load is less than the load threshold.

A hydraulic pump is driven by an engine. A hydraulic motor is driven by hydraulic fluid discharged from the hydraulic pump thereby causing a vehicle to travel. A controller controls a rotation speed of the engine and a displacement of the hydraulic pump. The controller acquires a tractive force of the vehicle. The controller changes the rotation speed of the engine to a low speed side in accordance with a reduction in the tractive force.
