You need to check the safety switch under the seat. Make sure it is plugged in and activating first. If it is then we will need to check it to make sure it is operating correctly.

Let me know what you find.

Seat switch is ok
Technician: Jon K., Small Engine Diagnostic Expert replied 8 years ago

By OK can I assume you mean that it is there and plugged in?

I am not sure if that is a normally open or normally closed switch (I believe it is a normally open closed switch) so we can do a few more tests with it. Unplug it completely and try your mower. If that works then we can stop. If not using a paper clip or a small piece of wire cross the two wires at the switch terminal and try it again.

Let me know how this works and we can keep going until we figure it out.

switch is ok .would not start with seat up .ok when sat on.
Technician: Jon K., Small Engine Diagnostic Expert replied 8 years ago
Ok then lets look at the switch located on the clutch/brake assembly. Find that switch (it should be right near the peddle) and do the same test as described above.
