3.0 THE PTO
The PTO is an essential part of the machine. This part drives the machine from the tractor, and ensures safe
use of the machine, providing it has been maintained and installed correctly. The PTO has its own CE
certification. Read the PTO manual, which you will find on the PTO itself.

3.1 PTO
LENGTH
The length of the PTO is crucial. If it is too long, the tractor and/or Verti-Core III can be damaged.
When the overlapping length of the sleeves drops below 150 mm (6”) at any time, the PTO can be damaged.
(Fig 8)
!! PTO length will change when the machine is lifted or used on a different tractor!!
In order to attain the right PTO length, when one has been purchased new or was previously used on another
tractor, you will have to do the following:
1. Couple the Verti-Core III to the tractor as described in Chapter 4.0.
2.
!! Switch off the tractor and make sure the tractor is secure and cannot start moving !!
3. Lower the Verti-Core III onto the floor until it is resting on the front and back rollers.
4. Measure the distance A between the PTO connection of the tractor and that of the Verti-Core III, from
groove to groove.
5. Measure length B of the PTO in its shortest position, from locking pin to locking bolt.
6. Split the PTO in two, and remove the protective cover from both ends.
7. Both the ends of the sleeves and of the safety covers have to be shortened: (B-A) + 75 mm (3”).
8. De-burr all parts, use some grease and assemble the parts.
9. Mount the PTO on the Verti-Core III side.
10. Couple the other end of the PTO to the tractor.
11. Check sleeve overlap.
!! Never use the machine with a damaged PTO protection cover; Replace it first!!
