COORDINATED IMPLEMENT CONTROL FOR WORK VEHICLE
A coordinated control method and system for a work vehicle having a primary implement and a secondary implement and one or more controllers. The controller(s) receive a primary implement position input, which is used to generate a primary implement control command to drive one or more primary actuators to position the primary implement. The controller(s) generate a secondary implement control command that is coordinated with the primary implement position input to drive one or more secondary actuators to position the secondary implement in a relative orientation with respect to an orientation of the primary implement resulting from the primary implement control command.
Hybrid hydrostatic-direct drive transmission
A hybrid hydrostatic-direct drive transmission configured to transmit power from a power source to a power output of a machine operating at low, intermediate, and high speed ranges is described. The hybrid hydrostatic-direct drive transmission may comprise a hydrostatic transmission portion including a first hydrostatic driveline having a first hydrostatic motor, and a second hydrostatic driveline having a second hydrostatic motor. The hybrid hydrostatic-direct drive transmission may further comprise a direct drive transmission. The hydrostatic transmission portion may operate alone to transmit power from the power source to the power output at the low speed range, and the direct drive transmission portion may operate alone to transmit power from the power source to the power output at the high speed range.
Apparatuses and methods for measuring saddle linkage position of a motor grader
A work machine includes a chassis and a linkage supported for movement relative to the chassis. The linkage has a lock pin aperture and a plurality of locking holes. The lock pin aperture may be aligned with one of the plurality of locking holes to position the linkage in use of the work machine.
PROJECT PATH OF TRAVEL OF BLADE ON A MOTOR GRADER
A motor grader having a front frame coupled with a rear frame, supported on front and rear wheels. A controller determines a position of actuators operably coupled with a blade attached to the grader, an articulation angle of the rear frame relative to the front frame, and a front wheel steering angle of the front wheels. The controller determines movement of the front and rear frames based on the articulation angle and the front wheel steering angle as the wheels travel over a ground surface. The controller determines a blade position and blade movement of with respect to the front and rear frames based on the position of actuators, rigid body acceleration of the motor grader, and physical characteristics of the machine assembly. The controller determines a blade trajectory path of the blade based on the movement of the front and rear frames, blade position, and blade movement.
MOTOR GRADER SNOW WING LINER
A snow wing assembly includes a snow wing moldboard having a material engaging side, a back side, and a plurality of openings formed in the material engaging side. The snow wing assembly also includes a plurality of attachment structures and a non-metallic liner having a first surface, a second surface, a leading side edge, a heel side edge, a top edge, a bottom edge, and a plurality of apertures extending between the first surface and the second surface. The first surface is configured to abut the material engaging side of the moldboard and the second surface is opposite the first surface and is configured to engage plowed material during a plowing operation. Each aperture of the liner is aligned with an associated opening of the moldboard, with an associated attachment structure extending through that aperture and fastened in an associated opening to secure the liner to the moldboard.
Inching systems and methods
A method of operating a machine with at least one hydraulically actuated friction clutch. The method includes selecting, via a mode selector, a starting point defining an initial setting. An endpoint defining a peak setting is selected via the mode selector. A control curve is employed based on at least the selecting of the starting point and the selecting of the endpoint. An inching pedal of the machine is positioned to between 0 percent depressed and 100 percent depressed. At least one control command is generated as a function of the employing of the control curve and the positioning of the inching pedal. At least one control valve of at least one hydraulically actuated friction clutch is operated according to the at least one control command.
Washout protection for a bit
A tool bit includes a working portion, and a shank portion defining a shank free end. The working portion includes a pair of side inserts, and a front insert.
WORK MACHINE AND METHOD FOR CONTROLLING WORK MACHINE
A work machine includes a vehicle body, a work implement movably supported relative to the vehicle body, an actuator connected to the work implement, and a controller. The actuator is configured to cause the work implement to move. The controller is configured to perform an automatic control to control the actuator so that a height of the work implement in a gravity direction is maintained even when a posture of the vehicle body changes, determine whether the work machine is in a non-working state in which the work machine does not perform work with the work implement, and stop the automatic control when the work machine is in the non-working state.
CIRCLE ASSEMBLY FOR IMPLEMENT
A circle assembly for an implement of a motor grader includes a circle and one or more mounting assemblies adapted to couple the circle with the implement. Each of the one or more mounting assemblies includes a first bracket coupled to the circle. The first bracket includes a first arm, a second arm axially spaced apart from the first arm, and a third arm connecting the first arm with the second arm. Each of the one or more mounting assemblies also includes a second bracket removably coupled to the first bracket. The second bracket is adapted to be coupled with the implement. Each of the one or more mounting assemblies further includes a fastener that removably couples the first bracket with the second bracket via the first arm and the second arm.
GNSS SUPPLEMENTED SLOPE CONTROL SYSTEM AND METHOD FOR A WORK VEHICLE
A work vehicle including a chassis, a ground-engaging mechanism, an input device, a global positioning system, and a controller. The input device providing a bench surface. The global positioning system configured to provide a chassis heading signal, a chassis inclination signal indicative of a main fall angle, and a chassis roll signal indicative of a cross slope angle. The controller configured to receive the chassis heading signals, record the chassis heading signal from a first location to a second location; use the recorded chassis heading signal as a reference chassis heading signal; receive a current chassis heading signal; determine an orientation error based on the reference chassis heading signal and the current chassis heading signal; and send a command to actuate the ground-engaging mechanism to shift the current heading to align with the reference heading based on the orientation error.
