@ The length of the draw rod assembly should be 560.00 mm (22.050"), which can be set by the calibrating
shims, see the spare part page

7.0 GROUNDSPEED
.
The groundspeed determines the hole spacing D in the drive direction, see fig.6. The VERTI-DRAIN doesn't
need a creeper gear, however if the customer wants a close hole spacing, the groundspeed should be low
enough, which depends on the tractor.
The gearbox has standard three different gear setting, resp. 1,2 and 3. When set in 3, reduce PTO revs till 400
rpm’s max, otherwise damage may occur. The input speed R on the PTO may be maximum 500 rpm. When
stones or rocks are expected, the input speed should be lowered.
With heavier tines, attachments or at maximum tine angle, the tineholders may start to float. Lower rpm's at that
time, before the tineholders start to turn upwards.
In Fig.6., a graph is drawn in which the relation between the groundspeed, the gear setting and the hole spacing
is given. If the tractor groundspeed is known at 500 rpm's of the PTO, the hole spacing can be determined at
different gearbox settings.
@ If the machine is not set correctly behind the tractor, see fig.1., different angles at the PTO may cause
vibration into the drive line of the VERTI-DRAIN. This vibration can hurt the machine and also the
performance of the holes in the ground.
@If the gear box setting is hard to shift, rotate the crankshaft a little till the shifting is possible. You can use the
“Combi-Tool”for easily rotating the crankshaft.
@ If the PTO shaft is incorrectly fitted (too long or too short), extra forces are applied to the input shaft of the
gearbox. Damage may occur.
* When the gearbox is shifted, shut off the tractor engine
