I have a 2010 x720 ultimate. It took me 4 hours of messing around with it to get it started on Saturday and today it won't start again. Once it was running it ran great. It seem's like there is no spark then it floods. I cleaned all the ground connection and checked for continuity on all the white ground wires I could find. I've tried everying thing I can think of.....new plugs, new fuel filter. The fuel pump pumps fuel through the filter. I've tried starting it with the fuel cap on and off. When I got it started on Saturday it popped a few times, them a few more, then enough to keep it running, then it cleared itself and started running great.

I can't believe that both coils would go bad at the same time. I need help, any suggestions?

Sorry to hear you are having problems with it. Since it is under warranty it may be best to have the dealer check it out but I'm sure some people will be along shortly with some suggestions on what else to look at. :trink39:

You're right, I thought it was a 2 year warrenty, I just checked and it's 4. If no one can come up with an easy solution, I'll get it to the dealer.

How many hours?

Did you check the fuse?

Sound like a faulty ignition module. :dunno:

I agree. Being so new I would let the dealer fix you up.

how often do you usually run your X720? do you use any fuel stabilizer? this winter has been a little slow on the snow action, if it has been sitting for a couple months without use is it possible that little water is in the gas tank?

I'm going to try tonight to get it started, if I can, I'll move my snow and get the tractor loaded and ready to go to the dealer.

I'll let everyone know what the dealer finds and share my learning’s for others. I'm a little skeptical of what they will consider warranty work.

Thanks everyone for your input. The dealer said it could take up to a week to get it fixed, so I'll talk you then.

Yup, this sounds like moisture in the gas.

Drain the tank, replace with fresh gas w/fuel treatment, let stand a couple days, then try it.

Thanks for bringing up water and old gas. Now that you mention it, the gas I smell on the plugs doesn't smell as potent as you think it should. The tank is full of gas, which is about 1.5 to 2 months old. I couldn't believe gas would go bad that quickly. And the first time I had the problem is when my baby spent the night outside, I guess she's never forgave me. She should be happy now, it's -3 outside but a nice comfy 58 in the garage.

It looks like I'll be staying up a little later tonight. It's off to the gas station to get some kind of gas treatment and fresh gas. We have 8-10 inches of snow forcasted starting tomorrow afternoon. I've got to be ready for the "Friday night" plowing. Hope my beverages don't freeze.

Mikestoy,

Really? a 200Hp on an 18 footer. Sounds like a tournament boat. It's gotta go easily over 60 mph.

I keep in mind it's not the gas! it's the ethanol in the gas! ethanol acts like a sponge when it comes to water in the air, it will suck the water right out of the air and deposited in your gas tank. you need to use a product like sta-bil. Look at the link below and you will see that they have a product designed specifically for gas that has ethanol in it. If you have water in your gas you need to drain the tank and then install new fresh gas that you have added the gas treatment to. Try to make sure that you keep the tank on your tractor full in all times, and only by enough gas to fill the tank on your tractor. Leaving a gas can in your garage partially full is the perfect situation for the ethanol to start sucking the water out of the air and into your gas can. Be especially leery in the spring and fall when temperatures warm during the day and cool at night, or any time when dew forms. lots of moisture in the air,is when water moves into your gas. Thanks to ethanol we all have to be more vigilant.

nflack. What ratio of Sta-Bil have you been using? Hard to believe moisture even @ 1 oz per gal.
I've had no problem with 2 or 3 month old gas with 2 oz./ Gal. when I get home with the gas.

Just an update. It's been a while since I did the original post but......... I ended up taking my x720 to the dealer, sure enough both coils were bad and replaced under warranty. Been running great since.

 

[TurtleBoy]

That is great to hear. :thThumbsU

 

[mikestoy]

, sure enough both coils were bad and replaced under warranty. Been running great since.

I can't believe that both coils would go bad at the same time.

Can you believe it now?

Under warranty, that's good
