Cardan shaft
The length of the cardan shaft has been selected at the factory so that
it fits almost all types of tractor. Only in exceptional cases is a correc-
tion of the cardan sha ft length required on individual tractors. The car-
dan shaft length must be che cked in the following way before first use:
Switch off the tractor
Perfor m all w or k onl y w ith the engi ne sw i tched off and the implement
at a standstill. Remove the ignition key. An accidentally switched on
cardan shaft can cause very serious injuri es.

Correct length
A cardan shaft which is too long must not be used. This damages the
drive bearings on the tractors and implements. The use of a cardan
shaft which is too long renders any warranty and guarantee claims null
and void.
Before coupling, check the length of the cardan shaft:
> Correct alignmen t and connection of the tractor and the implemen t.
> Check that the tractor drawbar eye is clean and lubricated.
> Fit both universal dri ve shaft halves (do not connect!)
> Hold both universal drive shaft halves together and check that
•
The protecti ve tube must be at least 5 cm shorter,
•
The overlap of the profile pipes for the drive must be at least 37 cm.
Shorten i ng the car-
dan sha ft
On the tractor side, the cardan shaft has a wide angle joint with an
angle of up to 80°. Make sure that the cardan shaft is not damaged du-
ring tight turns.
> Determine the correct shaft length.
> Shorten the protecti ve tube.
> Shorten the profile pipes for the drive.
The ends must both be cut to the same length.
> Deburr and clean the raw edges of the protectiv e tubes and profile
pipes to ensure that they are smooth and neat.
