5.0 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.
Shown version: VT 1200 (The same principle applies to the VT 1800.)

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-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:
(Figure 10)
1. Measure the distance between the PTO’s connection to the tractor and to the Verti-
Top, from groove to groove
(Figure 10, A)
, when the machine is connected to the tractor
and positioned on the ground at the right angle.
2. Measure the distance
(Figure 10, 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. Mount the PTO with the slip coupling at the Verti-Top side.
The torque of the locking bolt must be 80 Nm (700 lb.in.) and should be
checked every 40 hours.
