Kubota mower won't start when cold

Battery is over 12

Battery is over 10 under load

Removed glow plugs, hooked them back to the harness and grounded them to the battery. They came on. Bright orange.

Mower won't start using a portable jump start.

It only does this the first thing in the mornin. If I heat the garage up to 60 degrees for a few hours. It doesn't do it.

After it starts the first time of the day, its fine all day long.

Fresh fuel and two new fuel filters. I'm stumped. Help?

Move to Mexico. Does it smoke when first starting it? Sure the glow plug circuit is working?
Lower the viscosity of oil or just get a block heater till things warm. They have a nice one that goes
into coolant. Will heat it hot to the touch in 45min. Goes in place of a freeze plug

I wouldn't think so cause it happens when the outside temp is 40 degrees.

It has trouble starting around 40 and anything below that.

Yes i guess maybe I missed it but is it sitting in the garage with tempatures in the twenties all night and then by the time you try to start it it's 40. If so I would say that is normal. Option to plug it in?

Is the engine cranking and smoking out the exhaust while your trying to start it ? You should be able to start it at 40 degrees even with out good glow plugs, just may take a few more cranks.
