4.0 THE PTO
The PTO is a very important component that takes care of the drive from the tractor. It also
takes care of safe use of the machine, provided it is installed and maintained in the correct
manner. The PTO has its own CE certification.
Read the PTO manual! This manual is located on the PTO.
Figure 10
4.1 LENGTH OF THE PTO (Figure 10)
The length of the PTO is very important. If it is too long, it can damage the drive of the tractor
and/or the Verti-Quake®.
If the overlapping length of the cylinders becomes less than 150 mm (6”), it can damage the
PTO.
The length changes when the machine is lifted or when a
different tractor is used!
In order to set the PTO on the correct length, when a new one has been purchased or when
a different tractor is used, follow these steps:
1. Connect the Verti-Quake
®
to the tractor as described in Chapter 2,
section 2.1.
2. Switch off the tractor and make sure that the tractor is blocked well
and cannot move on its own accord!
3. Lower the Verti-Quake
®
on the subsoil until the knives are nearly touching the
subsoil and the skids are standing parallel with the subsoil.
4. Measure the distance between the PTO connection of the tractor and the PTO
connection of the Verti-Quake® from notch to notch.
5. Measure the distance B of the PTO in its shortest position from the locking pin
to the locking bolt.
6. Divide the PTO in two parts and remove the protection cap at both ends.
7. The ends of the cylinders and the ends of the protection caps must be made
shorter: (B-A) + 75 mm (3”).
8. Smooth off all components, use some grease and subsequently, assemble all
components.
9. Mount the PTO with the cam clutch at the Verti-Quake
®
side.
10. Attach the other end of the PTO to the tractor.
11. Check the overlap of the cylinders.

12
Never use the machine if it has a damaged PTO protection cap!
First replace the cap!
4.2 USING THE PTO
The following items must be checked for correct use of the PTO:
1. During the Verti-Quake
®
operations the angle of the pivot pins is not
permitted to be larger than 30 degrees.
2. The pivot pins must always be aligned.
3. The overlap of the cylinders must always be minimum 150 mm.
4. Never use the machine if it has a damaged PTO protection cap.
4.3 PTO INFORMATION AND MAINTENANCE
The PTO belonging to your Verti-Quake
®
machine is equipped with a cam-clutch
protection that protects the Verti-Quake
®
against overloading.
If the cam clutch becomes operative, the PTO has to be switched
off, the machine should be lifted off the ground and the start
procedure must be repeated.
Concise maintenance schedule of the PTO
Scheduled maintenance:
−Grease the grease points every 100 hours of operation or after the PTO has been
standing still for a long time.
−Check the PTO for damage to the protection caps and replace these caps if they
are not satisfactory.
−Check whether the safety stickers on the PTO are still present and intact.
Annual maintenance:
−Disconnect the PTO from the machine.
−Inspect all the components of the PTO.
−All the damaged components should be replaced.

7.0 DRIVING SPEED
The effectiveness of aerating is directly related to the soil conditions, the driving speed and
the number of revolutions of the PTO.
The recommended driving speed is 0.5 – 1.5 km/h (0.3 – 0.9 mph) with a number of
revolutions of the PTO of maximum 1,000 rpm for aerating with the Verti-Quake
®
.
The driving speed and the number of revolutions of the PTO should be tuned instinctively
related to the soil conditions and the required level of aerating.
8.0 START / STOP PROCEDURE
The start procedure is VERY important. If this procedure is not executed as described below,
serious damage to the Verti-Quake
®
could be the result.
The start procedure is as follows:
1. Observe the Verti-Quake
®
well and look whether all components function properly.
If this is not the case, the problems must be solved before using the
Verti-Quake
®
!
2. Connect the Verti-Quake® to the tractor.
3. Drive to the spot where the processing should take place.
4. Let the machine drop until the knives nearly touch the subsoil.
5. Engage the tractor in the correct gear with the four-wheel drive switched on.
6. Switch on the PTO with a low number of motor revolutions.
7. Raise the number of PTO revolutions to approx. 300 rpm.
8. Set the tractor in motion and let the Verti-Quake® sink into the ground with a smooth
movement.
9. Raise the number of PTO revolutions to the maximum value of 1,000 rpm.
10. Increase the speed to maximum 1.5 km/h (0.9 mph).
Figure 14
Adjust the top rod in such a way that the rear part of the skids is parallel
to the subsoil.
This lowers the pressure of the machine on the subsoil and prevents
damage to the subsoil. (Figure 12)
Work in straight lines; curves do damage to the subsoil.

17
Stopping occurs as follows:
1. Stop the forward movement of the tractor.
2. Lower the number of PTO revolutions to approx. 300 rpm.
3. Stop the PTO as soon as the knives are out of the ground.
4. Lift the Verti-Quake
®
smoothly out of the ground.
5. Go to the next spot and start again as described in the beginning of
this chapter.
NEVER engage the clutch of the tractor when the Verti-Quake
®
is operated! The
Verti-Quake
®
can push the tractor forward with high speed!
It is absolutely necessary to work according to the aforementioned procedures.
If the machine is placed into the ground without a running PTO, serious
damage to the machine could be the result.
You should drop the Verti-Quake
®
CAREFULLY into the subsoil.
If the machine is overloaded, a protective device built-in by means of the cam
clutch safeguards it.
9.0 USING THE VERTI-QUAKE
®
Before using the Verti-Quake
®
in a location, you should check the following items:
1. Are there loose objects in the field? First remove these objects.
2. Are there slopes? The maximum slope is 20 degrees for the Verti-Quake
®
.
Always go from top to bottom.
3. Are there cables/pipelines in the ground? If so, determine the depth of the
cable/pipelines and adjust the working depth of the machine to 60% of this depth.
4. Are there hard objects in the ground? Adjust the working depth.
5. Is there danger of flying objects (e.g., golf balls) that distract the attention of the
driver? If so, the Verti-Quake
®
CANNOT be used.
6. Is there danger of sinking/sliding away? If so, postpone the Verti-Quake
®
processing.
7. If the soil is frozen or very wet, postpone the activities until conditions improve.
10.0 TRANSPORTING THE VERTI-QUAKE
®
The user is responsible for transporting the Verti-Quake
®
in back of the tractor over public
roads. Verify the national legislation regarding the regulations.
On open fields, the maximum permitted speed is 12 km/h (7.5 mph) due to the weight of the
Verti-Quake
®
.
A higher speed can be dangerous for the driver and/or the public and can even damage the
machine.
When the machine is raised off the ground, the front axle of the tractor has to
support minimum 20% of its weight.

18
11.0 DETACHING THE VERTI-QUAKE
®
Figure 15
The machine can be detached from the tractor in the following manner:
1. Drive the Verti-Quake
®
to a parking area with a firm/flat subsoil.
2. Make sure that the tractor is blocked well and cannot move on its
own accord!
3. Switch off the tractor before descending!
4. Slide the support jacks 1 downwards by pulling the handgrip 2 outward and
secure the support jacks once more with handgrip 2.
5. Carefully drop the Verti-Quake
®
