(11) Blade control lever Blade cylinder (6) is driven by the oil delivery from blade pump (2). The supply oil flows through delivery line (3) to blade control valve (12).Blade control lever (11) controls the movement of blade (7). The control lever controls the following four positions of the blade:
RAISE
LOWER
NEUTRAL
FLOAT Leveling work is accomplished by using the mass (weight and size) of the blade in the FLOAT positionBlade cylinder (6) extends or blade cylinder retracts by moving the blade control lever.When blade control lever (11) is placed in the NEUTRAL position, oil to blade cylinder (6) is blocked. In this position, the blade (7) can be used as a stabilizer. The circuit pressure for the blade is limited by main relief valve (13).Blade Control Valve
