A hydraulic arrangement for implementing a float position is provided. The arrangement includes: a hydraulic cylinder having a first chamber and a second chamber, a first supply pipe connected to the first chamber and a second supply pipe connected to the second chamber; a volumetric control valve assembly located within a hydraulic pipe and arranged between the first and second chamber; a hydraulic fluid feeder in fluid communication with a hydraulic reservoir; and a controller having a raise position, a lower position, a neutral position, and a float position to control the hydraulic cylinder. The second supply pipe is fluidly connected to the hydraulic reservoir and the first and second supply pipes are substantially prevented from being fluidly connected to the hydraulic fluid feeder when the controller is in the float position.
