description Abstract WORK TOOL PITCH CONTROL SYSTEM FOR A MACHINE A control system (19) for a machine (10) is disclosed. The control system may have a first cylinder (34) operatively connected between a first side of a work tool (14) and an undercarriage (42) of the machine, a second cylinder (36) operatively connected between a second side of the work tool and the 10 undercarriage of the machine, and one or more electro-hydraulic valves (90, 92) configured to selectively regulate flow of pressurized fluid to the cylinders. The control system may also have a controller (52) configured to determine a difference between a desired pitch of the work tool and an actual pitch of the work tool, and compare the difference to a threshold value. The controller may 15 also be configured to move the one or more electro-hydraulic valves to change the flow of pressurized fluid to at least one of the first and second cylinders to adjust the actual pitch of the work tool to the desired pitch, based on the comparison.
