Troy-Bilt 8 HP - Manual (Page 11)

SECTION 2:
Before using your tiller or PTO
Power Unit for the first time, be­
come thoroughly familiar with the
operation of the controls by mov­
ing them to their various positions
while the engine is not running.
Taking the time now to fully under­
stand the location, function, and
operation of these controls will
greatly add to the productive use,
safe operation, and full enjoyment
of your new machine. The proper
operation of each control is dis­
cussed in detail in this Section.
Tiller and PTO Power Unit Controls
1. Wheels/Tines/
PTO Drive Lever
This lever engages power from
the engine to the transmission
(see Photos 2-1, 2-2, and 2-3).
There are three positions of this
lever: "FORWARD”, “NEUTRAL”
and “REVERSE”.
When you move the lever down
to the “FORWARD” position, it
raises the engine upward and tight­
ens the drive belt located between
the engine pulley and the transmis­
sion pulley. The transmission then
drives the wheels and tines in a
forward direction. (If the tines are
removed and replaced with a PTO
driven attachment, the lever will
apply power to the attachment.)
The lever will remain in “FOR­
WARD” until you tap or lift it
upward and let it go.
When you move the lever all the
way up to the “REVERSE” position,
it lowers the engine and causes
the drive belt to go slack. At the
same time, the rubber reverse disc
on the engine pulley comes into
contact with the transmission pul­
ley, causing the transmission to
rotate the wheels and tines (or any
PTO driven attachment) in a re­
verse direction. The reverse oper­
ation will continue as long as you
hold the lever up. When you re­
lease the lever, it will automatically
return to “NEUTRAL”. This is a
safety feature for your protection.
When the lever is in “NEUTRAL”,
the engine will continue to run, but
power will not be transferred to the
transmission.
IMPORTANT
Moving the lever to the “NEUTRAL”
position will stop all wheel and tine
motion, or power to any PTO driven
attachment.
To operate the Wheels/Tines/
PTO Drive Lever:
A. Practice shifting the lever as
described next. As you do, note in
the accompanying photos the vari­
ous positions that the clutch roller
takes on the belt adjustment block.
Your roller should be similarly po­
sitioned when you shift the lever.
B. For forward motion of the wheels
and tines (or to apply power to any
PTO driven attachment), push the
iever all the way down and release
it. See Photo 2-1. To return to
“NEUTRAL”, tap or lift the lever up
and let it go (Photo 2-2).
2-1: Push lever down for “FORWARD”.
The clutch roller (lower photo) will be
engaged below the adjustment block.
2-2: Tap or lift lever up to return to
“NEUTRAL”. The clutch roller (lower
photo) will rest anywhere on the face
of the adjustment block, depending
upon drive belt length and tension.
