Schemes of attachment
A cardan shaft length is deter-
mined by distance L (the shaft is
entirely moved) at horizontal posi-
tion of the lower rods. A shaft
lengthening is effected when lifting
the implement, so it is necessary
to check telescopic elements over-
lap in an upper position. A hinge
inclination is more from a PTO
side than from a power intake shaft
side.
Cardan shaft length L is deter-
mined at the implement turning by
a maximum angle with reference
to a tractor. If equality
А = В is not
observed, a rotation irregularity is
suddenly increases, resulting in
the shaft overloading.
A cardan shaft length remains un-
changed at the implement turning
with reference to a tractor. A rota-
tion irregularity of the cardan shaft
appeared on the way is compen-
sated by an angular velocity hinge
installation.
