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
hydraulic 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 FREEWFIEEL, then block all wheels
(Figure 4-29) to prevent the equipment
from rolling.
