Installing the Tine Attachment
1. Move the two PTO Power Unit swing­
out bolts outward and slide the washers
up against the bolt heads.
2. Remove the support block from under
the engine and slowly roll the power unit
back next to the tine attachment. Place
the support block back under the engine.
3. Remove the dust cap (or protective
wrapping) from the dog clutch coupling
on the tine attachment.
4. Carefully align the guide pin on the
PTO Power Unit with the alignment hole
in the tine attachment and bring the two
units together (Figure 4-27).

PTO POWER UNIT
OPERATING INSTRUCTIONS
A WARNING
To help avoid personal injury or
damage to equipment, read the attach­
ment's Owner's Manual supplied with
each attachment before installing or
operating an attachment. Please read
all control, operation and safety
instructions.
The following are operating instructions
specifically for the PTO Power Unit. Read
the separate Owner's Manual supplied
with each attachment before attempting
to assemble, attach, transport or operate
the attachment. If needed, please contact
us for a replacement manual. See the
back cover for customer support
information.

mounting hole.
5. 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 flat.
The bolts must be very tight - if you have
a torque wrench, tighten each bolt to
between 70 and 80 ft.-lbs.
IMPORTANT:
The swing-bolts must be
kept very tight to prevent damaging wear
to the dog clutch coupling, alignment pin
or the alignment hole. Check bolt
tightness every 2-1/2 operating hours.
6. Remove the engine support before
moving the tiller in a forward direction.
A WARNING
To help avoid personal injury, always
disengage the Tines/ PTO Clutch Lever
before towing any attachment.
Some attachments have a drive shaft or a
hydrauiic pump that is powered by the
engine on the PTO Power Unit. These
units are called Stationary Attachments,
since they remain in one location when
operating. Attachments can be towed to a
work site with the PTO Power Unit as
described in Operating Non-Powered
Attachments. Other attachments are
pulled or towed behind the PTO Power
Unit. These attachments are called Non­
Powered Attachments.
Setting Up Stationary Attachments
A WARNING
To help avoid personal injury, never
allow people to ride on any PTO Power
Unit or attachment.
1. Move the Tines/PTO Clutch Lever to
DISENGAGE.
2. Move Wheel Speed Lever (Figure 4-22)
to FREEWHEEL, then biock all wheels
(Figure 4-29) to prevent the equipment
from roiling.
