The key elements of Cross Slot庐 openers remain the blades, discs and pressure plates and how they interact in the 馃挶 soil. The
shown here are of a left hand SP blade (white) and pressure plate (green) fitted to a 馃挶 standard Mark 4 opener (black and grey). These components are brightly coloured for illustrative purposes.
The main advantages of the new 馃挶 SP system are:
Lower operating costs
Wearing parts are retrofittable to existing Cross Slot庐 openers
The blades self-align on the disc
