    I downloaded the elec diagram and it turns out there are three safety devices that block started operation.

    first is the seat switch

    second is the PTO switch

    third is the clutch/brake device.

    this is ridiculous!. the seat switch is easy to locate and test but I have yet to find the other two plus those two safety switches do not show up on the factory parts diagram(only on the elec diagram)

I like to start by making sure the starter gear not locked into the flywheel , this happens a lot on briggs take your hand turn the flywheel screen counter clock wise it will walk the gear down , you should be able to turn eng by hand now if not gas leaked into eng .
or eng is locked up.
Next I like to jump the starter solenoid to find it follow the heavy red wire from the battery it will led to it, there are 2 kinds 4 post and 3 post looks like you have 4 to test a 4 post unplug both small wires from the spades , you will need to small pices of wire hook one small wire to spade and ground it to frame of tractor now take the other wire hook it to the other spade and touch it to large stud that leads to the battery make sure you have parking brake set it may crank over, this by passes all safety switches and starter switch if it cranks over battrey good starters good solenoid is good .
safty switch on clutch pedal of mower deck engage switch not seat switch .
IF it does not crank over use a heavy wire or pliers jump large stud to large stud if cranks over solenoid is bad .

Sounds like a safety switch concern. Most mowers need the brake or clutch pedal depressed or the park brake engaged for power to go to the starter. Could also be the seat switch. My John Deere LT160 needs the brake pedal depressed or I can lock the park brake on and start it without being in the seat. Hope this gives you some ideas.

I have 2000 john deere 420 and it wont turn over


The starting circuit is dependent upon the clutch safety ans PTO being off. Here are some steps to take:
1. Ensure battery is fully charged
2. Turn key on and turn PTO on then back off. Listen for clunk
3. Press clutch in fully and turn key to start position. If still no sound at all, hold key in start position and move clutch foot up and down, listening for solenoid click. If click but no crank, starter or solenoid or battery cable connection is bad. Start by wiggling cables, looking for any looseness. Next check solenoid and cables. If that doesn't fix it, starter or solenoid may be bad. There may be a fuse in the circuit. Check them out also.
if it cranks but doesn't start, you have a fuel or ignition problem. Good luck. Let us know what you find

Won't start turn the key and it clicks. Replaced battery, air filter fine, fuel filter appears clear.


1. Check the battery terminals and leads are clean and the connections are tight.
2. Make sure the battery is fully charged. (Note that some tractor batteries require filling with acid and then charging before first use).
3. Check the starter solenoid, this is the electronic switch which allows heavy current to the starter motor. Check all the connections are clean and tight. Using a voltmeter check it works OK.
4. Finally check the starter motor electrical connections.
5. if everything else is fine it's probably the starter motor.
6. You can also check the starter has not jammed, either by turning the engine or by removing and replacing the starter.
Good luck

Battery fully charged, no headlights and no response when i turn the key?


Have you checked the wires on your starter? All voltage going from the battery to your vehicle must pass through the starter...It is either a loose connection or your starter is needing replaced.

Murray 17.5 HP mower - no noise when turning key? Maybe ignition?


Look near the starter solenoid for a fuse. It is probably under the hood near the steering column. If fuse is good, problem is likely a safety switch.

Turnover problem with toro 16-42z riding mower


A fully charged battery should read a minimum of 12.65, if it does not and connections and grounds are dirty then that's your problem. Start with a none fully charged battery.If you can bypass the solenoid and start it then the culprit is the solenoid. Good luck. donnyb60
