Attaching the Mower to the Tractor
continued
Check and adjust the P.T.O. operating length:
Check the minimum P.T.O. operating shaft length
(maximum compressed condition). It is essential
that the P.T.O. shaft is not fitted at this stage. Set
the tractor/mower combination with the tractor
straight ahead on a steep upward slope, with the
mower on level ground as shown. Gently reverse
the tractor a short distance to fully compress the
tow hitch drawbar. Apply the tractor handbrake,
stop the engine, remove the ignition key, apply the
mower handbrake and chock the tractor rear wheels
to prevent runaway.
Separate the two halves of the P.T.O. shaft and
assemble the large wide angle joint half to the trac-
tor (as shown on the P.T.O. guard). Assemble the
other half of the P.T.O. shaft to the mower. Ensure
that the release clips are fully engaged. Align the
two half shafts alongside each other and mark off
40mm from the end of the guards as shown below.
Disassemble the shaft halves from tractor and
mower. Remove the plastic guard from each half
using the following method.
Cut the inner and outer plastic guards at the marks
previously made. Measure the length of the
discarded guard cut ends and reduce the length of
the inner and outer shaft tubes by the same amount.
WARNING: PREVENT DAMAGE - Deburr the
shaft tube ends and remove all swarf. The
slightest burr will damage the Rilsan coating of
the shafts and a substantial reduction in shaft
life will result.
Fit greasing collar (item A), part no. 767822, to
the outer shaft and ensure that it is pushed fully
home. Drill one 25mm diameter hole in the inner
guard only, approximately halfway along its length
through one wall of the tube. Remove all burrs
from the hole.
Apply grease to the inner shaft and fit all guards to
both halves. Assemble the P.T.O. shaft and ensure
that the telescoping action is smooth and uninter-
rupted.
Do not make any other changes to the P.T.O. shaft
or guard assembly.
