CHECK THE LENGTH OF THE CARDAN SHAFT
1. After connecting the machine to the 3-point hitch, verify that the tool is in level and centered in relation to
the tractor through the adjusting devices.
2. Fit the cardan shaft between the PTO of the tractor and the flail mower.
3. Verify that the length of the cardan shaft is correct.
4. To do so, check what follows: the minimum coupling distance between the inner and outer tube is not
less than 180mm in every working position; at the same time, when minimally extended, the cardan
shaft can still move by at least 25mm.
5. If the minimum coupling distance is less than 180mm, the cardan shaft is short and must be replaced
with a longer one.
6. When minimally extended, if the cardan shaft can move by less than 25 mm, then it is long and
therefore it is necessary to shorten it.
7. ATTENTION: shortening the cardan shaft is complicated, the operation must be carried out carefully
following the instructions in the next chapter, otherwise the cardan shaft itself may be damaged
irreparably.

8
HOW TO SHORTEN THE CARDAN SHAFT
1. Through the hydraulic lift, bring the machine at the minimum distance from the tractor.
2. In this position, block the lift and turn off the engine.
3. Pull out the two parts of the cardan shaft completely.
4. Insert the female semi-cardan (tube with larger diameter) in the PTO of the tractor.
5. Insert the male semi-cardan (tube with smaller diameter) in the PTO of the machine.
6. With the two parts parallel, use a felt pen to mark the cutting point, as shown in picture "1".
1. Cut the plastic tube with a hacksaw on the line you previously marked on one of the semi-cardan.
2. Align the piece of tube you just cut at the end of the metal tube and then cut it.
3. Repeat the same operations on the other section of the cardan shaft.
4. Use a file to smooth down the edges of the metal tubes.
5. Clean and grease the two metal tubes and then insert one section into the other.
6. Mount the cardan shaft between the tractor and the machine, then verify the length again.
