Rubin 2.0
When the Rubin 9 was launched in 2011 it was just as the compact disc market was starting to get going. The heavy-duty Lemken short disc harrow stood out from the crowd with its large diameter, scalloped discs each mounted on a cranked leg with sizeable coil spring protection allowing it to work down to 13cm. All of these features have been carried over to its successor, the Rubin 10 along with a host of substantial modifications. We tested the 5.0m semimounted Rubin 10/500KUA.
Hard to hitch
The semi-mounted Rubin 10 has a Cat III headstock. Lemken now uses spherical bearings to cope with the higher forces, so the cultivator no longer just attaches to just the lower links, it also uses the top link. To avoid the headstock flopping to the ground when the implement is removed from the tractor you need to remember to use a pin to mechanically lock the frame – it is a task you will only forget the once! You also need to remember to remove the pin when hitching back up otherwise there is a risk of damaging
the bearing. As you may tell we are not fans of this locking pin arrangement as there is the risk of it being overlooked.
