STX38 mower wont' start

Mower sometimes just quits running. I charged the recently purchased battery. The starting solenoid makes a loud crisp click as though it is engaging but the starter does not turn. I don't want to pay the $90 to have JD dealership haul it in to their shop so I would like to fix myself, if I can.

Have you checked the output of the alternator.
got a ohm/volt meter? or a battery tester?
should be putting out 14 volts. may be the voltage regulator.
start there esp if you charge the battery and it runs for a hour.... hour and 1/2 then quits.

SOURCE: What causes JD 260 riding mower to start dying

It's the safety system that causes this. There is a switch under the seat that should activate when you are sitting in the seat. The switch can come loose or fail, the mounting can break, or the wires can come loose - any of these would cause the "engine dies when I engage the mower deck" behavior. Lift the seat, examine the switch. Rmove the switch and keep the plunger in with a piece of tape. Fixed? Then it's just the mounting or adjustment. Not fixed? It's the switch itself or the wires or connectors to it.

It could be a few things:

1. Check the belt that drives the blades; it could be broken or slipping.
2. Make sure the PTO Switch/Lever is working properly. The cable could be broken, or the spring that sometimes help to engage the blade could be broken.
3. There may also be a large stick lodged in the belt that drives the blades.

Good Luck!

SOURCE: the battery in my JD lawn tractor was dead; it

I suspect that the alternator/generator has gone bad, preventing the battery from chargine, or generating enough voltage to keep the electric pto on your mower engaged.

I think that it is located on the engine beneath the flywheel.

I hope this helps you.

Why poulan pro riding mower wont charge

First check your battery, make sure the cells are good and no bad cells. If that is good then the issue is under the flywheel. There is a coil under your flywheel that serves as a generator. You can just purchase a 2 am charger with a breaker, that will kick out when battery is charged and hook that up after each use. If you jump a unit or charge a unit with more than 2 amps, you can burn the generator coil out under the flywheel. Also check the magnet under the flywheel. I have seen them come out.

Cub Cadet LT1050-Replaced the solenoid, had starter checked out-it's good, battery has full charge, but mower won't start. Help!!

You need to check that there is a 12volt supply from the low tention wire at the solinoid when the key is turned, if there is not either the switch is bad, or the wire from the switch is bad, or the fuse has blown.

I have a riding mower that will not turn over. I used jumper cabels attached to my car, stupid I've been told. I have done this before and the mower will start. When attached the mower engine will...

it is hard to say exactly what the problem is, but it sounds like the starter, starter solenoid, and or a charging problem. 1. last year I am assuming that the battery was low on charge and once you jumped it, it would start with the key for the rest of the season? if yes your battery should be OK just make sure at the end of the season you disconnect it and store it some where cool but not freezing. if you had to jump it all the time the battery and charging system has problems,(cables)(?). 2. if you have to use the car to jump the mower make sure the mower and car are both 12 volt systems, and the car should not be running. 3. make sure the battery is fully charged and there is no corrosion between the cables and connections. 4. once you do the above you can jump the solenoid to see if the starter is bad, if it moves it should be good, if you have to jump the solenoid make sure the mower is in neutral and the wheels are locked so it cant jump forward. also make sure all your safety switches are engaged, most mowers have switches on the seat, the blade engageing handle, and breaks.
The lights might have a bad connection at the battery, follow the wires from the lights for fuses and check them, some models have to be started before you can turn the switch back to turn the lights on.

Mower sometimes will not start. Has new battery

You have to use a volt meter and test the ignition circuit to find out where the voltage stops. If you have 12 volts going in to and out of the switch, then switch is good

I have a john deere STX-38 Riding mower that keeps draining the battery and some times it wont even turn over "just goes click" thats it!!!

Many of the newer riding mowers slowly drain the battery due to the electronic components. The best way to prevent the battery from draining down in between uses is to install a battery disconnect switch. It only takes a few minutes to install and once it is installed it only takes a simple turn of the knob to disconnect the battery and prevent the battery from draining down. Most major automotive parts stores have them in stock. You can also get one from a mechanic shop whom may have greater access to auto parts.
If you can't find a battery disconnect switch, simply disconnect the negative terminal from the battery when not in use.

Stx38 won't start

Actually, this is a problem with many lawn tractors. John Deere makes a "Starter Assist Kit" that sells for about $25. After time, the electrical connections get a bit corroded and when you turn the key the solenoid doesn't get the full current it needs to be activated. I have made my own relay to overcome this problem on my STX38, have shared with many folks with positive results as well. Cost is about $5 total. If you still have this problem and would like a schematic of the "fix", go to:
Mytractorforum.com, go the the Lawn and Garden section, click on John Deere. When the page opens, search STX38 and look for the thread started by "Brad". Info is in there.

Good Luck.
