A guiding plate for coupling a plurality of hydraulic valves and a plurality of hose fittings which comprises a plate, and an identifying mark. The plate includes a plurality of apertures corresponding to the plurality of hydraulic calve and is positionable over the plurality of hydraulic valves. The identifying mark on the plate for each of the plurality of apertures, the identifying mark indicating the sequence of coupling of each hydraulic valve from the plurality of hydraulic valves with each hose fitting form the plurality of hose fittings.

Apparatus and method for coupling a plurality of hydraulic valves with a plurality of hose fittings

A closed loop feedback circle drive system utilized onboard a motor grader includes an operator input device, a blade, and a multi-speed hydraulic motor having a motor output shaft. The motor output shaft is mechanically linked to blade such that motor output shaft rotation drives rotation of the blade about a blade rotation axis. A controller is operably coupled to the operator input device and to the multi-speed hydraulic motor. The controller is configured to: (i) receive blade rotation commands via the operator input device to rotate the blade about the rotation axis in a commanded manner; and (ii) control the multi-speed hydraulic motor to implement the blade rotation commands, while repeatedly adjusting the rotational speed of the motor output shaft to reduce variations in a rotational velocity of the blade due to changes in blade loading conditions occurring during motor grader operation.
