Gator 620i gas in engine oil
Anymore info on this problem. I have a 09 620I with less than 40 hours on it with gas in the oil. It had it the first 10hrs also but did not check the level, just drained VERY thin oil. Mine got so full in the crank case it started smoking and missing till it burned some off. Is JD still passing this off on the customer or are they standing behind there product?
Just got mine back from the dealer for this problem and they gave me the same story everybody else is getting about not getting it up to operating temp. I am a mechanic and this is complete BS. I seen another posting where a dealer told someone they had to much idle time. My dealer told me I should leave it run as apposed to shutting off and re-starting. As a matter of fact I brought in with 37 hrs on it and they put 10 hrs on it letting it idle at the dealer to do their test which are BS. I have a shed full of green but it's going orange if they do not stand behind this. I'm surprised there is not a class action on this, as you all have said this is supposed to be the best equipment out there, lord knows we all paid to have the best. But now it looking like I have a $12k POS in the shed with no fix for it except get rid of it.

Gator 620i gas in engine oil
You've put a lot of time in to this. I'm a mechanic myself, and personally believeknow the line of BS JD is giving us about all cold gas engines put fuel in the oil is total crap. My biggest concern is not that there is a problem with the gator it is how JD is not stepping up to fix it or at least help out there customers that have basically spent around $12K for something that is not going to last. Personally I'm so angry with JD right now I'm trading in everything I have green on orange. I'm going to take a pounding on the gator since I only bought it 9 months ago, but it's take it now or take later. I've talked to customer service to just try and get a good amount of money back on the 620I to trade up to the 820 diesel but they say they can not do anything. I was going to trade in my 4520 open cab for a 4720 closed cab but now I'm going to trade it in on a Kubota. I'm at a loss on how this whole thing is being treated, you would think there will be a class action law suite for this. I know I'm just one little peon customer and there is really nothing I can do to JD, but that being said my shed has always been full of green, everything from the gator to ride mowers, zero turns and tractors. Up until now everything has been great and I've been proud to be a JD ownercustomer. But from the way this going down I will not buy even a JD hat after this and it's really sad, you try to buy American "and I know this is a Kawasaki engine" but the way this being handled is terrible.
Good luck with yours, hopefully you or someone can figure out and inexpensive fix. Me personally, I'm washing my hands of the whole company at my expense.

Gator 620i gas in engine oil
I wish your dealer was near me. I had a pretty good relationship with the local dealer, all though it was just me buying equipment not having any problems. I guess when you have problems is when you find out just how good of a relationship you have. The dealer I purchase my gator, 4520 and zero turn from has since sold out to new owners and is not going well. That being said I have found a good dealer a few miles further away and they have done more for me with this gator than the dealer I purchased it from.
As far as my gator goes I had excessive gas in the oil the 1st 10hrs but did not realize it at the time when I changed the oil. I myself own and run a repair shop and understand everybody makes mistakes and has problems. To me what makes good customer relations it how you handle the problem and take care of the customer when it happens "and don't have to many problems". I have read the bulletin that JD put out on this problem and for the most part it is total BS. Basically according to there bulletin every time you start up a gas engine "they may of said liquid cooled" you have to keep running it until it heats up to operating temp so that all the gas that got down in the crank case while it was cold will evaporate and vent out. They also said gas has a shelf life of 30 days and old gas will increase the problem, I personally work in the petroleum industry and I no gas over time will get stale but 30 days.
I guess a long story short is they have a problem with there product, there not owning up to it and there problem is going to cost me money. The new JD dealer I'm talking to offered me 8K for my 620I to trade up to a 820 diesel. So that would mean it cost me $100 an hour to run my gator over the last 10 months. There is not much I can do but take my little bit of business away from JD and just hope if I go Kubota there product is quality and where it's not they stand behind it. To me that is how all businesses should run.

I appreciate all the comments and advise. I have talked to JD customer service, they escalated it to a supervisor who contacted the dealer that I purchased it from and also had taken it to for the problem. I told them I did not want to debate the problems and or the cause of the problem "getting back to JD's bulletin of BS on the problem". All I want was a fair trade in value for my 10 month old gator and I would pay for an upgrade to the the diesel model. That sounds more than fair to me, they told me there was nothing they could do. As of right now the new dealer I'm talking with has a call in to his regional JD guy to see if he can get him to help with trade in value. The one catch to that is I"m looking to trade in my 3 year old open cab 4520 with backhoe and loader for new 4720 cab tractor with backhoe and loader, about a 28K upgrade. I told the salesman if they won't do anything with the gator I'm not buying another JD tractor. So unfortunately at the end of the day if they do help me out on the gator it won't be about doing whats right it will be about getting more money. I really don't want to change to Kubota but it will more or less be out of spite, right or wrong. Getting a Kubota tractor doesn't bother me much, but as the 1 posting said, I have a friend with a diesel Kubota RTV, I did not like it. So as of right now I'm so mad at JD I could spit "or worse", but I got to make sure I don't go from one bad deal to another.

Don't take this wrong but what you found is a way around the problem. We bought our Gator to use around the farm and for hunting "which is what I thought they were made for". Some days thats working it hard, pulling equipment around and running it for long periods of time, but more times than not it just riding back and forth to the barn which is about 800 yards one way. My gator is putting gas in the oil so fast that with in 20 hours of an oil change it is about a 1/2" to 1" over full. JD says all gas engines put gas in the oil when they are cold and then they burn it off when they heat up. The dealer told me they had this problem with I think he said the 90's gator. I had a 2X4 gator before this one and all we did with that was drive back and forth to the barn it never got worked hard "no suspension had no choice". Obviously all gas engines don't do it. Sad to see JD not standing behind this and now I see from the other posting not standing behind a fuel pump issue. I wonder if they have lemon laws on UTV's. Hell they cost as much as some cars.

I don't quit get that because you want more fuel when it's cold and leaned out as it heats up. With out the O2 it defently can't adjust to be efficent but I would think the problem with that would show up once it got hot. Maybe it just compensates off of engine temp richer cold than leans out when hot. Don't know how they do it or try to do it. I just had mine back to the dearler, they changed the oil and tweaked on the fuel. I can tell they leaned it way out, it almost cuts off when cold but doesn't. Hopfully this will help, they did give me the extended 2yr warranty but only because I bought a tractor.

I guess the biggest problem here is JD's lack of concern or action to make it better. I know it's been said somewhere in this string, when you buy JD you pay top dollar for what is suppossed to be the best. I have a 4720 tractor and a zero turn that I love. I actually love the gator minus the problem. It's just big business and bean counting - it will cost them less money to piss off and loss some customers than it would to admit a problem and correct it. Sad but true.

I have a 1 year old 620I that would fill the crank case in 30hrs. That is with a mix of driving but the bulk being driving about 1000yrds to the barn and shutting it off "which I thought a UTV was made for". I had an old 2X4 before that we only drove to the barn, because it had no suspension and could stand to drive through a rough field. That never had any problems "it was carburated". That's why it pisses me off so much when JD says all gas engines do this if you don't run them hard. I see a lot of ways to help this problem or maybe fix in here. I'm a mechanic myself and could tune on it or change things a bit to make it work better, but I did not go out and spend $12K to get a brand new suppossedly top of the line piece of equipment to have to work on it. It should be right from the start or they should standing behind it and making it right.

My local dealer gave me an extended 2yr warranty on mine "because I spent $40K on a tractor". I took it back to them and they played with the fuel mixture. They leaned it way out to the point it almost wants to cut off when coming back down from reved up when cold. Seems to be doing pretty well for putting gas in the oil, but the one time I did work it hard pulling a big load it seemed to not have enough fuel and the check engine light came on. Figure I have about 20 month of warranty left on it and it can go away after that. I'm suprised there has not been a class action law suit on this. Hell I could rep out side it so cut and dry.

Hotter spark plugs was a suggestion I made to the dealer, but with mine still having 2 years of warranty the last thing I want to do is tweak anything that would give them and out if something went wrong. I would think that would help whith burning all the fuel, the only problem I could think of would be during hard use creating excessive heat in the combustion chamber. It a fine line.

Knock on wood it's not doing bad since they leaned it out. I just keep checking the oil often. That new 50+hp gator looks realy nice but I do not know of anyone who has one. It's hard to stick with JD after all of this but I like the style of the gator kind of workplay design. I have friends with the mule "diesel though". They do good but they just seem like they are built for work only.

If there is a fix JD doesn't know it. Mine has the same problem, about 10hrs and the crank case is so full of gas and oil that it will start missing and smoking. I just drain the oil and put in new don't even touch the filter. My dealer even gave me a buletin from JD that all gas engines build up gas in oil and if you don't run them long enough to heat up and burn off it will build up. Total BS, bottom line is you have a $13k piece of crap and JD won't stand behind it. The part that kills me is they think it's OK to tell us we need to run them for a 1/2 hour everytime we start them up, don't know about you but we got our to run back and forth to the barn mostly "thought that was what they were made for". I'll quit now, I could right a book bitching about this but it won't do any good.

For what it's worth - I have a 625I I think 2010 with a 130hrs - took mine back to the dealer at 20hrs gas in oil - they tried tweeking the fuel system probably leaning it out, but long story short told me I was not using it right "not driving it long enough to warm up, you think if that was such an important thing it would come with a temp gauge" Given that is all total BS "I am a mechanic and own my own repair shop, not small engine" I did send out an oil sample for analysis - they can not actually check for gas but it was low vis. and high water traces "no metal" mine runs fine, when it does start to smoke and miss it is because the crank case is so full that the pistons
ods start slapping the oil in the crank case when I get on a incline. Now I just drain the old oil and put in fresh don't even touch the filter "most the time". The hotter plugs does make since but was afraid to void warranty at time what the warranty is worth I don't know. The bad part is I could not sell it to someone like this so I guess I'll be trading it in on something orange in the future. The other bad thing is I have a JD zero turn, riding mower and 66HP tractor - now I have no faith in the company.

I traded mine in at around 150 hrs and it was doing like yours when I got ride of it. We had a family friend as a JD salesman and he said it was the TPS. Don't know for fact but it made since. A little history on mine was it dump gas in the oil from day 1 even when it ran fine. They gave me letter from JD saying I did not run it long enough to heat up and evaporate the gas that got past the rings and into the crankcase "that all gas engines do". I got an 855D and it seams pretty good, I would not of got another JD but could bring myself to sell or trade in to anyone other than JD since they built and wouldn't stand behind the POS.
