STEERING CYLINDER
The steering cylinder is the double-acting type. The ball joint of the cylinder side is fitted to
the frame while the piston rod side ball joint is fitted to the center arm of the rear axle. The
cylinder tube and ball socket are of the screwing type, so the replacement is easy. The
cylinder tube has a box at the piston rod side to support the piston rod. The fluid leaving
the control valve of the power steering flows into the cylinder from the inlet port, extending
the piston rod. This motion of the piston rod steers the machine.
