Stopping The Engine - HUSTLER 3700 Operator's Manual

WARNING: Always wear eye protection when
checking the battery, acid can cause serious injury to
skin and eyes. If contact occurs, flush area with
clean water and call physician immediately. Acid
will also damage clothing.
Do not drink the battery electrolyte.
Do not allow open flame near the battery when
charging.
Hydrogen gas forms inside the battery. This gas is
both toxic and flammable and may cause an explo-
sion if exposed to flame. Always remove the nega-
tive ground first and replace it last.
Do not overfill battery.
Electrolyte may overflow and damage paint, wiring
or structure. When cleaning the battery, use soap
and water. Be careful not to get soap and water into
the battery. Clean the battery terminals with a solu-
tion of four parts water and one part baking soda
when they become corroded.
WARNING: Shorts caused by battery terminals or
metal tools touching metal tractor components can
cause sparks. Sparks can cause a battery gas explo-
sion which will result in personal injury.
Prevent the battery terminals from touching any
metal tractor parts when removing or installing the
battery.
Do not allow metal tools to short between the bat-
tery terminals and metal tractor parts.
WARNING: Incorrect battery cable routing could
cause damage to the tractor and battery cables. This
can cause sparks which can cause a battery gas
explosion which will result in personal injury.
Always disconnect the negative (black) battery
cable(s) before disconnecting the positive (red)
cable(s).
WARNING: Always connect the positive (red) bat-
tery cable(s) before connecting the negative (black)
cable(s).
Engine warm up
In cold weather, run the engine at half throttle for a few
minutes to allow engine oil and transmission oil to warm up.
WARNING: Never leave the machine running unat-
tended.

Stopping the engine

WARNING: Always apply the park brake when
leaving the seat.
Stopping the engine should be done according to the
following procedures;
REV F
1. Pull the throttle lever fully rearward to the low idle
position.
2. Release the HST foot pedals.
3. Engage the parking brake.
4. Place the transmission selector and lift control levers in
the "N" position.
5. Turn the key start switch to the "OFF" position.
6. Remove the key.
IMPORTANT: Failure to turn the key start switch to the
"OFF" position, after the engine stops, will allow the warning
lights to remain on, causing the battery to discharge.
IMPORTANT: Do not stop the engine immediately after
hard or extended operation. Keep the engine running at slow
idle for about 2 minutes to allow engine to cool down.
Operating the hydrostatic transmission and
PTO
Hydrostatic transmission
The hydrostatic transmission is controlled by the HST foot
pedals, cruise control switch, and transmission selector lever.
Figure 3-5, Figure 3-8 & Figure 3-9
When operating the transmission selector lever, place the
HST foot pedals in the neutral position. If it is difficult to
engage, slightly depress the Forward or Reverse foot pedal for
smooth engagement.
Never engage or disengage the transmission selector lever
when the unit is in motion.
With the transmission selector lever in "H" range (Figure 3-
10), ground speed can be varied from zero to maximum by
depressing the forward or reverse travel pedal. In "L" range,
speeds are about 60% of "H" range. Maximum speeds in
reverse are about a 65% of maximum forward speeds.
To stop the unit, release the pedal gradually (except on an
emergency). When released, the pedal returns to the Neutral
position automatically, stopping the unit. Sudden release can
result in an abrupt, and possibly dangerous stop.
For prolonged operation at a fixed forward speed, use the
forward travel pedal to attain the desired speed, then move the
cruise control switch to the "ON" position. Speed will remain
at the set value when the pedal is released.
To cancel the speed setting or stop, push the switch to the
"OFF" position or firmly depress the master brake pedal.
Automatic or Locked All Wheel Drive (AWD)
The transmission selector lever is used to select Automatic
Four-Wheel Drive or Locked Four-Wheel Drive.
When the Transmission Selector lever is located in the
inside slot, the tractor will run in Automatic AWD mode.
Figure 3-9
When the lever is placed in the outer slot, the mower will
run in Locked AWD mode and low range. Figure 3-10
When in motion, always bring the unit to a complete stop
before moving the transmission selector lever.
Automatic All Wheel Drive (AWD) means that the four-
wheel drive line is engaged automatically when the front
wheels start to slip, but, in normal operation, reverts to 2WD,
this provides sharp and smooth turns without damaging turf.
Locked Four-Wheel Drive should be used when additional
traction is required while operating in loose soil, wet, slippery
