1. A machine configured to travel on a ground surface, the machine comprising:
a frame;
a cab coupled to the frame and including a boom control member and an implement control member, the cab configured to support an operator of the machine;
a boom pivotably coupled to the frame about a first pivot axis;
a first hydraulic actuator coupled to the boom and the frame, the first hydraulic actuator configured to move the boom about the first pivot axis in response to the operator actuating the boom control member;
an implement pivotably coupled to the boom about a second pivot axis, the implement configured to engage the ground surface and configured to hold material;
a second hydraulic actuator coupled to the implement and the boom, the second hydraulic actuator configured to move the implement about the second pivot axis in response to the operator actuating the implement control member; and
a control processor configured to automatically move the first and second hydraulic actuators in response to the operator actuating the boom control member during a filling operation of the machine, wherein the filling operation includes moving the machine forward or rearward and discharging the material from the implement onto the ground surface, and
wherein the implement is a bucket configured to hold material, and
wherein the control processor is configured to automatically move the first and second hydraulic actuators in response to the operator actuating the boom control member, such that movement of the bucket relative to the boom is proportional to movement of the boom relative to the frame in response to the operator actuating the boom control member.
