Transmission
-
Consists
of
two separate trans-
missions, the Power Unit transmis-
sion and the Tine Attachment
transmission. Both transmissions
are encased in cast iron housings
and operate

gear oil. The housings are se-
curely connected by a locking col-
lar, a dowel pin, and two large
swing-bolts. By loosening the
swing-bolts, the Power Unit can be
disconnected from the Tine
Attachment and used as a separate
power source for optional powered
and non-powered PTO attachments.
