John Deere LX255 Kohler Starting Problems

LDX255 Engine and Seat Switch

• The JD LX255 uses a Kohler CV15S-41571. This is a 1-cylinder 426cc gasoline engine. This naturally aspirated engine is air-cooled and produces a maximum speed of 5.5 mph (8.8 kph). The LX255, like all John Deere riding mowers, is equipped with a number of safety switches; one is placed directly under the seat.

Seat Switch Starting Problem

• The safety seat is designed to shut the John Deere mower off automatically if the operator rises from the seat. This switch can be tested by removing the plug from the seat switch and jumping the connection using a connecting wire. If the direct wire works, the switch is bad. Buy a new seat switch in this case. This is a test procedure only; do not operate the LX255 mower in a direct wiring condition.

Ignition Coil Starting Problem

• A starting problem with the ignition coil occurs after some years of use that often befuddles owners. A bad ignition coil is a common issue with the small Kohler engine, and is indicated by not getting a spark to initiate ignition. The coil for a 15 HP Kohler engine is a specific part in the $40 to $50 range.

Burning Odor Starting Problem

• A burning odor indicates a battery charging issue that can occur when the pto circuit for the blades fails. The pto clutch magnet gives off a burning odor, but also damages the voltage regulator, causing the charge circuit to fail and draining the battery. The pto fits inside the pulley driven by the clutch, and looks like an upside down hat. In this case, the part and the voltage regulator likely needs to be replaced.
