For dynamic braking, Free-Wheeling valves must be
closed (Cam down – Buttons out) at all times when
tractor is in operation.

1. Cam Down (Traction Drive)
2. Cam Up (Free-Wheeling)
IMPORTANT: DO NOT push or pull (tow) tractor with
another vehicle as transmission damage will occur. When
transporting use truck or trailer. To manually push tractor
with engine stopped, open Free-Wheeling valves by
rotating cam up. (Valve is located under rear deck). This
presses buttons in and opens the by-pass. Place Speed
Selector in the neutral (N) position. The tractor may now
be pushed only short distances (10 to 15 feet). Greater
distances will result in transmission damage because of
a lack of transmission oil circulation.
PTO switch(es) control rotating parts. Keep hands,
feet, hair and clothing away from rotating parts.
Front and Center PTO Switch
To engage Implement Power, lift switch up to
(On) position to start attachment rotation. To
disengage, push switch down (Off) position
to automatically apply blade brake and stop
attachment rotation.
Rear PTO Switch
To engage Implement Power, pull switch out
to (On) position to start attachment rotation.
To disengage, push switch into (Off) position
to automatically apply blade brake and stop
attachment rotation.
NOTE: The PTO Switch(es) MUST be disengaged before
engine will start. They should also be disengaged before
operator leaves seat.
IMPORTANT: Set Throttle at 1/3 before engaging PTO(s).
