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.

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-Top.
If the overlapping length of the cylinders becomes less than 150 mm (6”) at any time, 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-Top to the tractor as described in Chapter 5.
Switch off the tractor and make sure that the tractor is blocked well and
cannot move on its own accord!
2. Lower the Verti-Top onto the subsoil until it stands on the front and back roller.
3. Measure the distance between the PTO connection of the tractor and the PTO
connection of the Verti-Top from notch to notch.
4. Measure the distance B of the PTO in its shortest position from the locking pin to
the locking bolt.
5. Divide the PTO in two parts and remove the protection cap at both ends.
6. The ends of the cylinders and the ends of the protection caps must be made
shorter: (B-A) + 75 mm (3”).
7. Smooth off all components, use some grease and subsequently, assemble all
components.
8. Mount the PTO with the cam clutch at the Verti-Top side.
9. Attach the other end of the PTO to the tractor.
10. Check the overlap of the cylinders.
