39.7. The Seat Safety Switch consists of a pair of
simple metal contact tangs attached to the seat
mounting bracket. See Figure 39.7.

• The yellow wire with white trace is connected to
the front spade terminal on the seat safety
switch. When the seat is vacant, the tab on the
seat bracket closes a ground path in series with
the PTO switch. If the PTO is ON and the seat is
empty, the circuit is completed, shorting-out the
primary windings of the magneto, turning-off the
engine.
• The yellow wire with black trace is connected to
the rear spade terminal on the seat safety
switch. When the seat is vacant, the tab on the
seat bracket closes a ground path in series with
the brake switch. If the brake is not applied, and
the seat is empty, the circuit is completed, short-
ing-out the primary windings of the magneto,
turning-off the engine.
• The most common problems are likely to be
caused by physical damage: a broken insulator
between the switch and the seat bracket, an
unplugged wire, or a bent tang.

39.8. On the 1000 series tractors the starter solenoid
is mounted at the left rear corner of the frame.
The mounting bracket is visible beneath the left
fender, and the solenoid itself is accessibly by
removing the battery. See Figure 39.8.
Figure 39.8
• When the proper safety conditions are met,
(brake applied, PTO OFF) the orange wire with
white trace energizes the windings that magne-
tize an iron core, pulling the contacts closed
between the two heavy posts, connecting bat-
tery power to the starter motor.
39.9. The 1500 series tractors use a starter solenoid
that is actually part of the starter.
39.10. The starters on the Kohler Command engines
have the starter solenoid on the starter. See Fig-
ure 39.10.
