Tractor wont start.

[tractor boy 88]

L 175 I just purchased ,it qas running .I powerwashed tractor . I started it up after. I forgot and left ignition on all night. Battery dead next morning. Charged up and tried starting. I engaged glow plugs first then tried starting , won't start. Checked all connections . Acts like no fuel or no spark oe elctrodes . Need help

'won't start' ?
Does that mean it doesn't crank the engine over or
it DOES crank the engine, but won't run ??

It turns over fine , just won't fire

 

[GreensvilleJay]

OK. do the glow plugs actually heat up ?
perhaps you've blown a fuse ? best to confirm they're all good

 

[tractor boy 88]

Im no

It turns over fine , just won't fire
I'm not too familiar with fuel injection. Bled fuel from pitcock screw. Didn't seem like much fuel coming out from injectors. How much should be coming out during turnover

Only fuses I saw on top were just 3 ,and 3 wires going across ,all intact

Does any smoke come out of the exhaust while you are cranking it over? If so, what color? If not, then you have a fuel delivery problem. We need more details to help troubleshoot.

if you don't have it, there's the WSM for free at www.kubotabooks.com
last page has wiring for L225 which might be similar ? it has 3 fuses........

I'd check the voltage at the glowplugs to confirm they are working. it looks like they're in series ,so if one is bad, you won't get ANY to heat up = spin but no run

No smoke from exhaust. I'll work on injection tomorrow. I'll check voltage as well. I disconnected wiring and cleaned contacts. I left a fan on it over night just in case it's a moisture issue.

When you turn the key to the on position, you should hear a single distinct click along with continuous fast clicking sound. That would be the fuel shutoff opening up and the fuel pump operating. Listen for those sounds and report back. BTW, you should also hear a single distinct click from the fuel shutoff closing when you turn the key off.

Ok if it was running fine then it should be relatively easy to get it running again.

Since it is new to you I will start with basic information.
It is diesel so has no ignition system. It runs on diesel fuel, not gas (which I see in your post but this is a misspelled word). But gas won’t get a diesel to run so don’t put any gas in the tank!

I assume you probably know how to start it but will go through the steps (assuming it is still wired up like it came from the factory- which is a BIG assumption).
Turn key to first position (run position) There are two additional positions for headlights low then high.
Set the fuel lever back (pull to rear) about half way (just to be sure).
Push the clutch pedal down.

Turn the knob (on right side of dash) to the left and hold it there. Turns on glow plugs.
Count off a good 10 seconds.
Before you get to 10, pull out the decompression knob (black choke looking knob on the left side of dash).
Release the glow plugs and then turn same knob to right to crank the engine (and also power the glow plugs).
Engine should spin at a fast speed and then release (push in) the decompression knob.
Engine should fire off quickly.
Adjust throttle to idle

I suggest you will probably need to clean all ends of both battery cables (4 total ends), maybe replace the battery, maybe replace the starter, maybe adjust and lubricate the decompression mechanism on front of engine, maybe inspect the glow plug circuit and replace the glow plugs and indicator. You may want to replace the air filter.

If your tractor has a different wiring scheme (wiring is hacked up), take some pictures of the dash for advice.
