The spring 21 and chain 30 latch into a catch 39, which is also arranged on the square guide 5, and is secured by means of a pin 40.
If the auxiliary wheel 14 and its clamping device are now to be removed from the rear wheel 15, the locking pin 40 is unlocked and pressure is exerted on the lever 31 by hand, causing it to disengage from the catch 39 and, after it has pivoted away from it, according to the tension of the Tension spring 21 folds over. This allows the unloaded spring 21 to be unhooked from the arm 22 and chain 30. The linch pins 36 and 37 of the bolts 32 and 33 are then released, whereupon the entire clamping device including the auxiliary wheel 14 can be removed from the rear wheel 15 of the tractor.
