The biggest difference between these two ploughs is the reversing mechanism. While the EurOpal works with a purely hydraulic reversing mechanism, the Juwel uses an electro-hydraulic mechanism. In addition, Juwel allows you to adjust the inclination of the plough from the cab. It is also important to know that you can use the Juwel with DuraMaxx ploughing bodies which are extremly wear-resistance. Despite from that, we do not produce the EurOpal anymore due to various innovations. Best wishes, Your LEMKEN Social Media Team
