Malfunction Reason Remedy
Plough frame turns up to the mid-
dle position and stops.
The required switch-
over pressure for the
turnover ram has not
been reached by the
tractor hydraulics.
a) By means of removing
the washers (U) the
pre-adjusted switch-
over pressure will be
reduced. Taking out of
one disc means a pres-
sure reduction of ca.
10 bar. The washers
(U) will be found be-
hind the plug (V).
b) Check the hydraulic
assembly of the tractor
and if required main-
tain it.
The plough frame turns but the
turnover ram switches over before
reaching the half-turned position
and the plough frame turns back

a) The pre-adjusted
switchover pres-
sure is too low.
b) The inner turn-
buckle is too long.
c) The bearing of the
turnover device is
damaged.
a) Increase the pre-
adjusted turnover pres-
sure by means of fitting
additional washers (U),
one washer = 10 bar
increase of the switch
over pressure.
b) Shorten inner turn-
buckle.
c) Check the bearings
and replace if required.
The turnover ram switches over,
without turning the plough frame.
a) The pre-adjusted

adjusted switchover
pressure by means of
an additional washer
(U).
b) Replace hydraulic ram.
