ATTENTION: MANUFACTURER OF THE IMPLEMENT CARDAN-DRIVEN FROM
THE TRACTOR PTO SHAFT SHALL INFORM YOU IN ADVANCE ABOUT THE NECES-
SITY OF APPLICATION OF A SAFETY CLUTCH, CLUTCH DESIGN FEATURES AND
CONSEQUENSES OF THE IMPLEMENTS APPLICATIONS WITHOUT THE SAFETY
CLUTCH!
When you need to decide on the purchase or operation of the cardan shaft follow
the implements and cardan shaft manufacturers’ guidelines first of all. It is recommended
to apply with the tractor the implements with active working attachments where the length
between the articulations of the fully off-set cardan shaft does not exceed 1 m..
When coupling the implements with RLL or FLL (Figure 5.10.2), the length of the car-
dan shaft is determined by distance L (fully off-set cardan shaft) with the lower links placed
horizontally. Shaft extension occurs when the implement is lifted therefore in up position it is
necessary to check overlapping of extensible components. In joint of the cardan shaft large
angularity appears in transport position of the implement when the tractor PTO shaft is dis-
abled. Cardan joints are not large and equal to each other in operating position, and usually

is assured. Therefore in this case an extensible cardan shaft with gimbal joint with
guard housing can be used.

with the implements connected via RLL and FLL
In course of the implements coupling via DH-1 -01, DH -1 or DH-3V (Figure 5.10.3),
where PTO shaft and PRS axles are parallel and not shifted relative to each other in fore-
and-aft plane (right and left), distances A and B from the connection point to PTO shaft and
to PRS are approximately equal, and maximum length of cardan shaft L is determined when
the implement turns around maximum angle turn relative to the tractor, an extensible cardan
shaft with gimbal joint with guard housing can be used.
