5.0 THE POWER TAKE-OFF (PTO)
The PTO is a very important component. 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 8
5.1 LENGTH OF THE PTO
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-cut. 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 to the correct length, when a new one has been purchased or when a different
tractor is used, follow these steps
(see Figure 8)
:
1. Measure the distance between the PTO’s connection to the tractor and to the machine, from groove
to groove, when the machine is connected to the tractor and positioned on the ground at the right
angle.
2. Measure the distance B of the PTO in its shortest position from the locking pin to the locking bolt.
3. Divide the PTO in two parts and remove the protection cap at both ends.
4. The ends of the cylinders and the ends of the protection caps must be made shorter: (B-A) + 75 mm
(3”).
5. Smooth off all components, use some grease, and then assemble all components.
6. Attach the other end of the PTO to the tractor.
7. Check the overlap of the cylinders.
Never use the machine if it has a damaged PTO protection cap.
First replace any damaged parts!
