7.0 DRIVING SPEED
The pitch in the driving direction depends on the driving speed. When a small pitch is
desired, the driving speed must be sufficiently low, which depends on the tractor or the Verti-
Power.
The rpm input of the PTO may not exceed 540 rpm.
If hard objects are expected, this speed must be lowered.
With heavier tines, other applications or with the maximum tine angle, the tine holders may
start floating. Lower the rpm as well in that case, before the tine holders slam upwards.
If the Verti-Drain
®
is not correctly mounted behind the tractor, see fig.8, different PTO
angles can cause vibrations in the messenger bar of the machine. These vibrations
can damage both the machine and the holes in the ground.
If the PTO is shortened incorrectly, or when another tractor is used, the gear casing
can be overloaded, resulting in damage.
