6. Move the two swing-bolts into
the slots of the tine attachment.
Alternately tighten each bolt until
they are tight enough to make the
concave washers on the bolts flat.
The bolts must be very tight - if
you have a torque wrench, tighten
each one to between 70-80ft.-lbs.
See Photo 4-44.
IMPORTANT - The swing-bolts
must be kept very tight to pre­
vent damaging wear to the ‘dog’
clutch couplings, alignment pin
or the alignment hole. Check
bolt tightness every 2-!^ operat­
ing hours.
7. Remove the engine support be­
fore moving the tiller in a forward
direction.

Some attachments have a drive
shaft or a hydraulic pump that is

operated (they can be towed to a
work site by the PTO Power Unit
as described in “To Operate Non-

Other attachments are simply
pulled or towed behind the PTO
Power Unit. These attachments
are called “Non-Powered
Attachments.”
