CONTROLS & OPERATION, cont'd
Throttle Control Lever (I)
nOTE: When set in a given position, a uniform engine speed will be maintained.
Throttle Control Lever - Push the throttle control lever forward to increase the engine
speed. The mower is designed to operate with the throttle control lever at full throttle
(FAST)
when the mower is being driven and the mower deck is engaged. Pull the
throttle control lever rearward to decrease the engine speed (SLOW) .
Power Take-Off (PTO) Electric PTO (J)
The PTO switch operates the electric PTO clutch mounted on the bottom
of the engine crankshaft. Pull the switch knob upward to engage the PTO
clutch, or push the knob downward to disengage the clutch.
The PTO switch must be in the “OFF” position when starting the engine.
Ignition Switch (K)
WARNING: Never leave a running machine unattended. Always
disengage PTO, set parking brake, stop engine and remove key to prevent
unintended starting.
The ignition switch has three positions:
STOP
— The engine and electrical system is turned off.
RUN — The riding mower electrical system is energized.
START
— The starter motor will turn over the engine. Release the key immediately
when the engine starts, the key will automatically return to “Run” position.
note:
To prevent accidental starting and/or battery discharge, remove key from the
ignition switch when mower is not in use.
Hour Meter & LCD Service Minder (If Equipped) (L)
The LCD service minder will remind the
operator of maintenance intervals for
changing the engine oil, air filter service,
low engine oil and low battery warnings.
When the key is rotated out of the STOP
position but is not in the START position, the
LCD service minder & hour meter will briefly
display the battery voltage, followed by the
mower’s accumulated hours.
note:
When the ignition key is out of the STOP position the hourglass symbol is
illuminated/blinks to indicate it is recording the hours of mower operation, regardless of
whether the engine has been started.
• Change Oil - The LCD screen will alternate the letters “CHG”, followed by “OIL”, followed
by “SOON”, followed by the meter’s accumulated time. “CHG/OIL/SOON/TIME” will
alternate on the display for 7 minutes after the meter reaches 50 hours. This oil service
minder interval will occur every 50 hours. Before the interval expires, change the
engine oil as instructed in the Engine Operator’s Manual
• Low Oil - The LCD screen will alternate the letters “LO” followed by “OIL”, followed by
the meter’s accumulated time, which indicates the engine has low oil pressure. This
is common when starting an engine. The indicator will remain active until the engine
sufficiently builds pressure after starting. If it remains on with the engine at full speed
and after a few minutes of operation, stop the mower immediately and check the
engine oil level and add as instructed in the Engine Operator’s Manual. If the oil level
is correct and the indicator persists, contact an authorized service dealer.
nOTE: The low oil pressure function only works if the engine is equipped with an oil
pressure switch.
• Low Battery - At startup, the battery voltage will briefly display, then changes
to accumulated hours. The letters “LO” followed by the letters “BATT” will display,
followed by the meter’s accumulated time. “LO/BATT/TIME” is displayed on the LCD
when the voltage drops below 11.5 volts. When this occurs, the battery is in need
of a charge or the engine’s charging system is not generating sufficient amperage.
Charge the battery as instructed in the Product Care section of this manual or have
the charging system checked by your local service dealer.
• Air Filter Service - The LCD screen will display the letters “CLN” followed by the letters
“AIR”, followed by “FILT”, followed by the meter’s accumulated time. “CLN/AIR/FILT/
TIME” will alternate on the display for 7 minutes after the meter reaches 25 hours.
This air filter service minder time interval will be every 25 hours. On intervals that are
common with oil service, the oil message will be displayed first followed by the air
filter message.
Accessory Switch/Power Bagger Assist/12 Volt Accessories
Receptacles (M)
The receptacles for optional accessories are on the control panel and right side of mower.
The receptacles are for a 12 volt outlet and head light.
Headlights (Not Shown/If Equipped) (N)
The headlight located in front of the control panel. The headlights are ON whenever the
ignition key is rotated out of the STOP position and OFF when the ignition key is moved
to the STOP position.
Leg Pad (O)
The leg pad is located in front of the operator’s position to provide a cushion between the
operator and the mower. Refer to the Adjustments section for instructions on adjusting
the leg pad position.
Operator’s Platform (P)
The operator’s platform is at the rear of the mower.
Suspension Adjustment Rods (If Equipped) (Q)
The mower operator’s platform suspension firmness is adjustable. Moving the two
adjustment rods to one of four combinations (insert FIGURE) will provide a firmer or softer
operator’s platform suspension.
Transmission Bypass valves(R)
The transmission bypass valves are located on the RH and LH Transmission (one for each
transmission). When in use, the two valves open a bypass within the hydrostatic
transmissions, which allows the mower to be pushed short distances by hand. Refer to
the Assembly section for additional instructions.
CAUTION: Never tow the mower. Towing the mower with the rear wheels on
the ground may cause severe damage to the hydrostatic transmissions
Hydrostatic Transmission Oil Reservoir (S)
The hydrostatic transmission oil reservoir is connected by hoses to the RH and LH
transmission assemblies, and is located behind the access panel in front of the
operator’s platform.
nOTE:
Prior to the initial operation of the mower, check the hydrostatic transmission oil
level. Refer to Checking the Hydrostatic Transmission Oil Level on page 18 .
Before Operating Your Machine
1. Before you operate the mower, study this manual carefully to familiarize yourself with
the operation of all the instruments and controls. It has been prepared to help you
operate and maintain your machine efficiently.
2. Fill the fuel tank with only clean, fresh, unleaded gasoline with a pump sticker octane
rating of 87 or higher. When the fuel reaches 1⁄2” (12.7 mm) below the bottom of the
fill neck, stop. DO NOT OVERFILL. Space must be left for expansion.
• This engine is certified to operate only on clean, fresh, unleaded gasoline. Fill
only with clean, fresh, unleaded gasoline with a pump sticker octane rating of
87 or higher.
• Do not use gasoline left over from the previous season, to minimize gum
deposits in the fuel system.
• Gasohol (up to 10% ethyl alcohol, 90% unleaded gasoline by volume) is an
approved fuel. Other gasoline/alcohol blends are not approved.
• Methyl Tertiary Butyl Ether (MTBE) and unleaded gasoline blends (up to a
maximum of 15% MTBE by volume) are approved fuels. Other gasoline/ether
blends are not approved.
3. Check the engine oil level as instructed in the Engine Operator’s manual.
4. Check the hydrostatic transmission oil level. Refer to Checking The Hydrostatic
Transmission Oil Level in the Product Care Section.
5. Check the rear tire inflation pressure is 10-12 psi (69-82.7 kPa).
nOTE:
New tires are over-inflated in order to properly seat the bead to the rim.
6. Check that all nuts, bolts and screws are tight.
7. Check the tension of the deck drive belts.
a. Remove the deck cover
b. The tension of the deck drive belts are maintained by a spring mechanism that
adjusts for wear and stretch.
c. Examine the belts for cuts, fraying, and excessive wear. Replace if any of these
are detected.
d. Replace the deck cover.
8. Check if deck is level. When correctly adjusted the mower deck should be level side to
side, and the front of the deck should be approximately 1⁄4” (6.4 mm) lower than the
rear of deck. If deck needs to be leveled, refer to the Service section.
9. Lubricate all pivot points listed in the Service section.
10. Adjust the leg pad and operator’s platform suspension (36 Inch Deck Only)for
operator’s maximum comfort, visibility and for maintaining complete control of the
machine. Refer to the Assembly & Set-Up section for instructions on adjusting the leg
pad and suspension.
