Tractor won't start

[Michael Beattie]

Question....
I have a Kubota b7610....
Was running fine... Turned it off to answer phone... Now won't start...
I bypassed the sensors on both the PTO and clutch... Won't start...
I bypassed the safety switches under the seat... Won't start...
I tried to start it between the starter and celanoid... Turns over but won't start...
Fuses are good... Fuel and filters good...
Any ideas???
Ignition maybe...
Is there a way to access that and bypass it?
Any ideas are appreciated...
Thanks!

DID IT TURN OVER?

I bypassed the sensors on both the PTO and clutch... Won't start...

DID IT TURN OVER?

I bypassed the safety switches under the seat... Won't start...

DID IT TURN OVER?


I tried to start it between the starter and solenoid... Turns over but won't start...

NOW YOU SAID TURNS OVER .......DOES IT TURN OVER ON THE OTHER THREE????

Fuses are good... Fuel and filters good...
Any ideas???
Ignition maybe...

AINT NO SUCH THING - DIESELS NEED FUEL,AIR AND COMPRESSION AND A SAFETY SWITCH THAT WILL DRIVE YOUR ASS CRAZY!!.......

Is there a way to access that and bypass it?
Any ideas are appreciated...

WHEN IT TURNS OVER....ANY SMOKE? YOU GLOWING THE PLUGS AT ALL ???

 

[Michael Beattie]

The tractor does not turn over with the different sensors and switches bypassed... Only when jumped between celanoid and starter... But even then won't start...
No smoke... And glow does occur for start...
New battery...

First try moving the HST pedal back and forth while turning the key.

Second, check all fuses, when you turn the key to on do gauges move?
lights? Anything?

If your getting nothing, look for the main fuse by the starter.

Third call it a solenoid, not a (celanoid)

Yes it could have a switch, but highly unlikely, your not going to get it to start by just jumping power to the solenoid as you need power to the fuel stop solenoid too.

Did you forget to push your kill cable back in? I did that once . . .

 

[Michael Beattie]

Already checked the fuses.....
Have tried pushing HST pedal in and out multiple times...
Gas gauge rises when key is turned on...
Lights, blinkers etc all work...
I'm not sure what this kill cable you speak of is....
In 12 years of running this tractor I've never had to deal with one of those..

Is it in neutral?

What were you doing with it when you shut it down to answer the phone? Double check that the PTO is off?

I hear this all the time at work. 99% of the time it's the HST, either the switch is bad or it's adjust too sensitive....moving the HST pedal back & forth while holding the key to start, clutch pushed in, sometimes it'll find that sweet spot where it'll try to start. If it does, the switch is either adjusted too sensitive or there is another adjustment causing the HST pedal to fail to return to neutral.

You said it's a new battery, did you clean the terminals when you replaced the battery? Also check the ground connection. When you jumpered the solenoid did you have the key on? As NIW hinted you would need to have the key switch "on" for the fuel shutoff to open for starting. Next would be to get a wiring diagram so you can check the starter circuit step by step to find a broken wire or loose connection.

Thanks everyone for you're input...
As it turns out the ignition relay under the dash was bad...
Power in.... But not going out....
