CAUTION
An operator presence switch (seat switch)
will cause the engine to stop if the blade
clutch is engaged and the operator is not in
the seat. The function of this switch should
be checked by the op erator raising off the
seat and engaging the blade clutch; the en-
gine should stop. If the switch is not work-
ing, it should be repaired or replaced be-
fore operating the mower.
disconnect the safety switches; they are
for the operator's protection.
IMPORTANT: DO NOT engage the blade clutch
when transporting the mower across drives, side-
walks, loose materials, etc. DO NOT engage the
blade clutch with the PTO shaft disconnected
(the mower deck removed from tractor).
CAUTION
If the cutting blades strike a stationary ob-
ject while mowing, stop the mower immedi-
ately, disconnect the spark plug wires, lift
the deck, and inspect the deck and blades
thoroughly for damage. Make sure that the
blade timing has not been dis turbed (the
blades should be at 90 degrees to each
other). Refer to Blade Overload Shear
Bolts on page 83 if blades are out of time.
Also, make sure the blade retain ing nuts
are torqued to 60 lb·ft (81 N·m).

STOPPING THE MACHINE

tion and then move the FSC lever backward to
the NEUTRAL-PARK position.

in the 1/2 throttle position.
3. Disengage the blade clutch.
IMPORTANT: DO NOT disengage the blade
clutch with high engine speed (above 1/2
throt tle) since the brake action on the blade
drive will cause premature wear of the brake
