Abstract:
A hydraulic system (76) for a machine (10) is disclosed. The hydraulic system may have a tank (78) configured to hold a supply of fluid, a pump (80) configured to draw fluid from the tank and pressurize the fluid, a first cylinder (34) operatively connected between a first side of a work tool (14) and an undercarriage (42) of the machine, and a second cylinder (36) operatively connected between a second side of the work tool and the undercarriage of the machine. The hydraulic system may also have a first electro-hydraulic valve (96) associated with the first cylinder and configured to selectively regulate a flow of pressurized fluid to the first cylinder independently of the second cylinder, and a second electro-hydraulic valve (98) associated with the second cylinder and configured to selectively regulate a flow of pressurized fluid to the second cylinder independently of the first cylinder.
