When the steering handle is
swivelled 180°, the PTO shifter
and the gear shifter change
sides. Now you change PTO speed in
opposite direction (see figure S,
page 33).

an automatic reversing lock (A/6) (Lock-
ing lever). This prevents the PTO for the
hoe from being engaged while the trac-
tor is in reverse. It also prevents the re-
verse gear from being engaged while
the PTO is at work.
