ADJUST PTO SHAFT LENGTH
IMPORTANT: A long PTO shaft is supplied with
machine to accommodate large variations in the
tractor's PTO and 3 point locations. For some tractors
this shaft is too long and must be cut to correct length
or gearbox damage may result.
1. With the aerator vertical or angled slightly forward,
lower the aerator until the gear box shaft is
approximately the same height as the tractor PTO
shaft. This is the shortest distance between the two
shafts.
2. Measure the distance from the lock groove of the
tractor PTO shaft to the lock groove of the aerator
gearbox PTO shaft. Record this dimension.
3. Fully collapse PTO shaft and measure the distance
between the lock pin collars. Record this dimension.
4. At it's shortest length, the two halves of the PTO
shaft must have at least 1.5 inches (37 mm) of
additional clearance to collapse. If the dimension in
step 2 is not at least 1.5 inches (37 mm) greater than
the dimension in step 3, the PTO shaft is too long,
proceed to step 5. If there is enough clearance to allow
PTO shaft to collapse, proceed to step 9.
