These are special snow ploughs, with a continuously expandable left part of the shield, weighing approximately 1.300 – 1.400 kg.
- On the one hand, these ploughs can minimize their transport width (by pulling the shield) and at the same time use the entire width of the shield in the extended state.
- Another advantage of these ploughs is that their working width is in each position of extension of the shield part.
- These ploughs are produced in all-steel or with a plastic shield.
