Wanting to boost his spraying capacity Johannes Eder made his own front tank to go with his Lemken Sirius 10/1600 mounted sprayer. Starting point for the project was a 600-litre Hardi tank. To this he welded a new channel section frame for the lower links and also repositioned the top link coupling so the sprayer could be kept close to the tractor. On the left-hand side, perforated sheeting was used to create a storage area, while a locker box was added to the right.
