OPERATION Executing a "Y" Maneuver For low traction conditions, follow these procedures for zero turns (the "Y-maneuver"): To turn clockwise (front of machine moves toward RIGHT) when traveling FORWARD: Using the Mower Deck WARNING Make certain the area to be mowed is free of debris, sticks, stones, wire, or other objects that can be thrown by the rotating blades. 1. Come to a stop. 2. Slowly move both lap bars rearward (no more than 1/2 maximum reverse speed) to initiate REVERSE travel. NOTE: Do not engage the mower deck when lowered in grass. Premature wear and possible failure of the "V" belt and PTO clutch will result. Fully raise the deck or move to a non-grassy area before engaging the mower deck. 3. Slowly move the LEFT lap bar forward while maintaining the RIGHT lap bar in the rearward travel position. 4. To stop the turn and re-initiate FORWARD travel, slowly move the RIGHT lap bar from the REVERSE travel position to a FORWARD travel position equal to that of the LEFT lap bar. 1. Use the deck lift pedal (a) to raise the deck to its highest position, place the clevis pin (b) attached to the mower into the desired index hole on the deck height index, then slowly release the deck lift pedal (a) (Figure 34). b 5. For counterclockwise turns, reverse the above procedure. Stopping the Mower 1. Move both drive control levers to the neutral position to stop the motion of the mower. a 2. Push the PTO switch downward to the disengaged position. 3. Use the deck lift pedal to raise the deck to its highest position and secure in place with the clevis pin attached to the mower. 4. If dismounting the mower, move the drive control levers fully outward in the neutral position, engage the parking brake, move the throttle control lever (if equipped) to the FAST position, turn the ignition switch to STOP and remove the ignition key from the switch. WARNING Do not leave the seat of the mower without disengaging the PTO, moving drive control levers fully outward in the neutral position, and engaging the parking brake. If leaving the mower unattended, turn the ignition key OFF and remove. Driving on Slopes Refer to the Slope Gauge to help determine slopes where you may operate safely. WARNING Do not operate on inclines with a slope in excess of 15°/26%. The machine could overturn and cause serious injury. 1. Always drive across slopes, never up and down. Control the speed and direction of the mower using primarily the control lever on the downhill side of the mower, with the uphill control lever remaining essentially in a fixed position. 2. Avoid turning downhill if possible. Start at the bottom of a slope and work upward. Always slow down before turning. 3. Use extra care and go slowly when turning downhill. Operating the PTO Operate the PTO as follows: 1. Move the throttle to approximately the mid-throttle position. 2. Pull the PTO upward to the "ENGAGED" position. 3. Advance the throttle to the operating speed (full engine speed). The operator must remain in the mower seat at all times. If the operator should leave the seat without turning off the power take-off switch, the mower's engine will shut off. Figure 34 2. Mow across slopes, not up and down. If mowing a slope, start at bottom and work upward to ensure turns are made uphill. 3. On the first pass pick a point on the opposite side of the area to be mowed. 4. Engage the PTO knob and move the throttle control to the operating speed (full throttle) position. 5. Remove the clevis pin, raise the deck to the highest (transport) position, place the clevis pin in the desired position and secure with the clevis pin. Lower the mower deck to the desired height setting. 6. Slowly push the drive control levers forward to move the mower forward, and keep the mower headed directly toward the alignment point. NOTE: The speed of the mower will affect cut quality of the lawn. Mowing at full speed will adversely affect a high quality cut lawn. Control the ground speed with the drive control levers. 7. When approaching the other end of the strip, slow down or stop before turning. A U-turn is recommended unless a pivot or zero turn is required. 8. Align the mower with an edge of the mowed strip and overlap approximately 3". 9. Direct the mower on each subsequent strip to align with a previously cut strip. 10.To prevent rutting or grooving of the turf, if possible, change the direction that the strips are mowed by approximately 45° for the next and each subsequent mowing. WARNING Be careful when crossing gravel paths or driveways. Disengage the PTO knob and raise the deck to the highest/transport position before crossing. NOTE: When stopping the mower for any reason while on a grass surface, always: • Make sure the drive control levers are in neutral. • Engage the parking brake. 20

OPERATION
Executing a “Y” Maneuver
For low traction conditions, follow these procedures for zero turns
(the “Y-maneuver”):
To turn clockwise (front of machine moves toward RIGHT) when traveling FORWARD:
1. Come to a stop.
2.
Slowly move both lap bars rearward (no more than 1/2 maximum reverse speed)
to initiate REVERSE travel.
3.
Slowly move the LEFT lap bar forward while maintaining the RIGHT lap bar in the
rearward travel position.
4.
To stop the turn and re-initiate FORWARD travel, slowly move the RIGHT lap bar
from the REVERSE travel position to a FORWARD travel position equal to that of
the LEFT lap bar.
5.
For counterclockwise turns, reverse the above procedure.
Stopping the Mower
1.
Move both drive control levers to the neutral position to stop the motion of
the mower.
2.
Push the PTO switch downward to the disengaged position.
3.
Use the deck lift pedal to raise the deck to its highest position and secure in place
with the clevis pin attached to the mower.
4.
If dismounting the mower, move the drive control levers fully outward in the
neutral position, engage the parking brake, move the throttle control lever (if
equipped) to the FAST
position, turn the ignition switch to STOP and remove
the ignition key from the switch.
WARNING
Do not leave the seat of the mower without disengaging the PTO, moving
drive control levers fully outward in the neutral position, and engaging the
parking brake. If leaving the mower unattended, turn the ignition key OFF
and remove.
Driving on Slopes
Refer to the Slope Gauge to help determine slopes where you may operate safely.
WARNING
Do not operate on inclines with a slope in excess of 15°/26%. The machine
could overturn and cause serious injury.
1.
Always drive across slopes, never up and down. Control the speed and direction
of the mower using primarily the control lever on the downhill side of the mower,
with the uphill control lever remaining essentially in a fixed position.
2.
Avoid turning downhill if possible. Start at the bottom of a slope and work
upward. Always slow down before turning.
3.
Use extra care and go slowly when turning downhill.
Operating the PTO
Operate the PTO as follows:
1.
Move the throttle to approximately the mid-throttle position.
2.
Pull the PTO upward to the “ENGAGED” position.
3.
Advance the throttle to the operating speed (full engine speed).
The operator must remain in the mower seat at all times. If the operator should leave
the seat without turning off the power take-off switch, the mower’s engine will
shut off.
Using the Mower Deck
WARNING
Make certain the area to be mowed is free of debris, sticks, stones, wire, or
other objects that can be thrown by the rotating blades.
NOTE:
Do not engage the mower deck when lowered in grass. Premature wear and
possible failure of the “V” belt and PTO clutch will result. Fully raise the deck or move
to a non-grassy area before engaging the mower deck.
1.
Use the deck lift pedal (a) to raise the deck to its highest position, place the clevis
pin (b) attached to the mower into the desired index hole on the deck height
index, then slowly release the deck lift pedal (a) (Figure 34).

2.
Mow across slopes, not up and down. If mowing a slope, start at bottom and
work upward to ensure turns are made uphill.
3.
On the first pass pick a point on the opposite side of the area to be mowed.
4.
Engage the PTO knob and move the throttle control to the operating speed (full
throttle) position.
5.
Remove the clevis pin, raise the deck to the highest (transport) position, place the
clevis pin in the desired position and secure with the clevis pin. Lower the mower
deck to the desired height setting.
6.
Slowly push the drive control levers forward to move the mower forward, and
keep the mower headed directly toward the alignment point.
NOTE:
The speed of the mower will affect cut quality of the lawn. Mowing at full
speed will adversely affect a high quality cut lawn. Control the ground speed with
the drive control levers.
7.
When approaching the other end of the strip, slow down or stop before turning. A
U-turn is recommended unless a pivot or zero turn is required.
8.
Align the mower with an edge of the mowed strip and overlap approximately 3”.
9.
Direct the mower on each subsequent strip to align with a previously cut strip.
10. To prevent rutting or grooving of the turf, if possible, change the direction
that the strips are mowed by approximately 45° for the next and each
subsequent mowing.
WARNING
Be careful when crossing gravel paths or driveways. Disengage the PTO knob
and raise the deck to the highest/transport position before crossing.
NOTE:
When stopping the mower for any reason while on a grass surface, always:
•
Make sure the drive control levers are in neutral.
•
Engage the parking brake.
