5. Measure the distance from the locking groove
on the end of the tractor PTO shaft to the locking
groove on the aerator gearbox PTO shaft
(Figure 14). Record this distance. Example: 70
cm (27.5 inches).

6. On the PTO shaft, measure the distance from
the center of locking pin ball on one end to the
center of the locking pin on the other end
15). Record this distance. Example: 81 cm (32
inches).

7. Using the smaller of the two measurements in
Figure 14 and Figure
from the distance in
(32 inches) minus 67 cm (26.5 inches) equals
14 cm (5.5 inches).
8. The example measurements show that the shaft
is 14 cm (5.5 inches) too long. Add an extra
1.2 cm (1/2 inch) to be sure that the PTO shaft
will not bottom out when the aerator is lifted to
its highest position.

(Figure
12, subtract that distance
Figure 15. Example: 81 cm
Example: 14 cm (5.50 inches) plus 1.2 cm (1/2
inch) equals 15 cm (6.00 inches).
9. Slide the PTO shaft tubes together until they are
fully collapsed. Verify that the inside tube does
not protrude into the cross and bearing section
of the outer tube
more will have to be cut off the inside tube, to
correct the problem. Proceed to next step.

into the cross and bearing section of the outer
tube (Figure

11. Separate the two halves of the PTO shaft
(Figure 17).
12. Measure the distance from the end of each
tube to its safety shield
distances.

13. Using the dimensions determined in step 8,
locate, mark and cut off the shield and tube from
each PTO half
Note:
More will have to be cut off the inside
tube if it was protruding into the cross and
bearing section of the outer tube.
