Next the other clamp 4 can be positioned at a maximum length of 280 mm ( 11”) away from clamp 3.
If the length is more ( measured when the draw rod is in its neutral position), damage to the springs and
other components may occur.
Be very careful in fitting the springs on the eye nuts (5/6), because the spring has to be stretched,
which can be dangerous.
@ It is important to adjust all springs at the same pre tension at a machine. The tension can be
reduced by reducing the length 280 mm. The spring can be taken out as well.
@ The tine holder can be turned upwards, when the assembly is done correctly. Check whether the
springs or eye nuts hit something after the installation.
@ With the auxiliary springs assembled, the capacity may increase, but we still have to be aware of
overspeeding the machine. Like with all other Verti-Drains with a rear roller, the tines may turn
towards the roller and hit the roller for different reasons.
@ When we apply too much spring force on the tines ( especially in combination with the 12 mm (
½”)), we may destroy the hole edge, since the spring is pulling hard at the moment the tines are leaving
the ground. Extra spring force is not advised for such applications.
