Hello,
I have here with the Kuhn rake GA9531, the working speed of 18km / h increased to 22km / h, in order to mow perfectly with the Pöttinger mowers in a train and you rakes to then pick it up with the loader wagons.
On the wear / repair period, I have not changed anything, because still 40% occlusion you can still drive 21km / h and I would otherwise change the mower, so that everything is in harmony.
