WARNING

：
Tractor is very difficult to
steer with differential locked.
Do not engage the differential lock when driving the
tractor on the highway or when ground speed is
above 8 km/h.
To operate the differential lock, depress and hold
the pedal down until the lock is positively engaged.
It is best to engaged the differential lock while the
wheels are turning slowly to minimize shock loads
to the drive line. If a wheel spins at high speed, as
on ice, reduce engine speed to idle before engag-
ing the lock, or damage may occur. The differential
lock is released by releasing the pedal.
NOTE: In some instances the lock may remain
engaged after the pedal is released. This may oc-
cur if one rear wheel tends to turn at a faster speed
than the other. Should this happen, the lock may
be disengaged by either of two ways:
Decrease the drawbar pull by raising or disen-
gaging the implement so that neither wheel
tends to slip.
――
OR
――
Rapidly apply and release a light braking load to
the slipping rear wheel.
PTO CONTROLES AND OPERATION

standard
All models operate through the standard 1 3/8 in.
(34.9 mm) diameter, 6-spline output shaft rotating
at 540 rpm , the speed at which most PTO driven
equipment is designed to operate.
If your tractor is equipped with 2-speed PTO then
the symbol on the proof-meter relates to 540
rev./min. PTO speed when the lower PTO speed
range is selected.
