An auxiliary flow adjustment system and method are disclosed for controlling an auxiliary hydraulic function on a machine in accordance with commands from an operator. The auxiliary flow adjustment system includes operator controls that control a hydraulic control valve. The control valve controls flow rate and flow direction to the auxiliary hydraulic function. When the auxiliary flow adjustment system is activated, the operator can use the operator controls to select a desired flow rate and flow direction for the auxiliary function and maintain the desired flow rate and direction without further use of the operator controls. When the flow adjustment system is activated while a non-zero flow rate is selected, the desired flow rate and direction can be set to the current settings. A resume control can retrieve and command the previously stored desired flow rate and direction. Controls can be used to increase and decrease the set flow rate.

Proportional auxiliary flow adjustment system and method

A construction machine is provided. The construction machine includes a chassis and a ground engaging member (such as a wheel or a track) operable to support and move the chassis over ground. The construction machine further includes a work implement (such as a bucket) coupled to the chassis; a cab mounted on said chassis and having a user seat, and a first controller (such as a joystick) accessible to a user seated in the user seat. The joystick controls at least one of moving the work machine over ground and movement of the bucket. The joystick has a first actuator (such as a trigger button) that is operable to selectively engage ride control functionality.
