squeezed against spring tension, freed from the
neutral lock position (see Neutral Latch Levers
below) and released, permits the pump to send oil
to the wheel drive motor at the rate set by the
ground speed control lever. When both traction/
steering levers are released, the mower will move
ahead in a straight line if the engine is running and
the ground speed control levers have been moved
forward out of the neutral position. Steering is
accomplished by squeezing the traction/steering
lever on the side to which the turn is to be made. If
both traction/steering levers are squeezed at the
same time, the mower will stop and then backup.
The mower can then be steered in reverse by
squeezing one of the traction/steering levers closer
to the handle than the other.
7. Neutral Latch Levers:
Pivoted inside each handle there is a neutral latch
lever which works with each of the traction/steering
levers. When either of the traction/steering levers
is squeezed and its neutral latch lever pushed
forward and engaged in the neutral lock position,
the traction/steering lever is held in a position
where its pump should not be sending any oil to
the wheel drive motor. (If this is not the case, see
Initial Adjustments 6 and 7.) The neutral latch
levers should be engaged in the neutral lock
position before starting the engine. The hardware
for the neutral latch should be "snug" to retain the
latch in the "on" or "off"positions.
8. Operator Presence Levers:
Located above the outer ends of the right and left
handles, these levers must be held down on the
handles against spring pressure when the engine
is running in order to move the ground speed
selector levers out of neutral or engage the blade
clutch. Releasing the operator presence levers
with the ground speed selector levers in any
position other than neutral or the blade clutch
engaged will shut off the engine.
9. Freewheeling (pump relief) Valves:
A “T” valve located on the side of each hydraulic
OPERATING INSTRUCTIONS
pump when opened will permit the mower to be
pushed forward or pulled in reverse without the
engine running. To override the braking force of
the hydraulic system, turn each valve counter-
clockwise two turns, move the mower as you wish
and then turn each valve clockwise two turns to
shut the valves.
10. Hour Meter and Tachometer:
Located at the lower left edge of the control panel.
When the machine is running the tachometer
displays engine rpm. When the machine is off it
displays running time.
B. Initial Adjustments.
1. Disconnect the spark plug wire.
2. Check the tire pressure. Caster Wheels should be
inflated to 25 psi. Drive Wheels should be inflated
to 15 psi. Note: New tires are overinflated in order
to properly seat the bead to the rim.
3. Check that all nuts, bolts and screws are tight.
4. Check the tension of the deck drive belts:
a.Remove the deck cover shield and engage the
blade clutch.
b.Make sure the belts clear the belt guides by
1/8" to 1/4".
c.The tension of the deck drive belts should be
adjusted so that a ten-pound pull between two
pulleys deflects each belt about 1/2". Do not
overtighten these belts. The blade clutch
should engage with only moderate force.
d.Replace the deck cover shield and disengage
the blade clutch.
5. The tension of the pump drive belt should be
adjusted so that a five-pound pull between the
engine traction drive pulley and the pump drive
pulley opposite the idler pulley deflects the belt
about 3/16".
6. The long traction/steering control rods which run
down to the pump control levers on each side of
the handle assembly should initially be adjusted so
that when the ground speed control levers are in
neutral and the traction/steering levers are released
from the neutral lock position, the mower stands
still with the engine running. If the mower starts to
creep forward or to the rear in this situation, then
