7.0 DRIVING SPEED
The effectiveness of the aeration depends upon the condition of the soil, the driving speed,
and the speed (rpm) of the PTO.
To aerate using the Verti-Quake
®
, a driving speed of between 0.5 and 1.5 km/h (0.3 – 0.9
mph) is recommended, in combination with a PTO speed of max. 540 rpm.
The driving speed and the rpm of the PTO should be adjusted according to the soil condition
and the amount of aeration needed.
8.0 START/STOP PROCEDURE
The start procedure is
VERY
important. If this procedure is not followed exactly as described
below, serious damage may occur to the Verti-Quake
®
.
The start procedure is as follows:
1. Visually inspect the Verti-Quake
®
and make sure all parts are functioning properly.
*!! If they are not, these problems must be resolved before the Verti-Quake
®
is to
be used !!
2. Check the oil level in the gearbox. The oil level should be in the centre of the gauge glass.
3. Connect the Verti-Quake
®
to the tractor.
4. Drive to the place where the soil is to be treated.
5. Lower the machine until the knives are almost touching the ground.
6. Switch on the four-wheel drive. Switch on the tractor in the right gear.
7. Switch on the PTO at a low speed (rpm).
8. Slowly raise the PTO speed to approx. 300 rpm.
9. Start the tractor moving and smoothly lower the Verti-Quake
®
into the ground.
10. Raise the PTO speed to a maximum speed of 540 rpm.
11. Raise the driving speed to a maximum of 1.5 km/h (0.9 mph)

@ Adjust the top rod in such a way that the rear part of the dragging legs
are parallel to the ground.
This will reduce the pressure of the machine on the ground and will
prevent damage to the soil.
(fig. 12)
@ Always work in straight lines. Curves may damage the soil to be
treated.
