I've got a 790 with about 70 hours on it. Lately I've noticed that it seems to be seeping antifreeze from "somewhere" around the thermostat housing/waterpump area. However, I cannot pin-point the location (e.g., overflow bottle, hoses, housing, waterpump) since it seems to be a very small leak.<br>
<br>
Does anyone know if a nearly new 790 is particularly prone to leaking antifreeze from any specific location? (I'm trying to avoid calling the dealer since even though it's under warranty, they want to charge me $200 to put it on their rollback and transport it to the dealership!!)<br>
<br>
Any assistance would be appreciated! Thanks!<br>

Has anyone replaced the thermostat in the 790? The manual says that it should be replaced every two years...BUT the manual also gives no procedures other than to say "see your John Deere dealer". What's the catch? Why would I need to go to the JD dealer just to replace the thermostat? Does anyone have the procedure for replacing it?<br>

My buddy was finally able to figure out what the problem was -- his battery had an internal short in it. Once he replaced the battery (and the fuses again), it worked fine.

A buddy of mine clains he saw an ad on ESPN for a new line of compact tractors (starts with M??) that lifted a 790 on its three point hitch and a Kubota on the FEL at the same time. Has anybody else seen this ad? Is this for real?????<br>

Anybody have trouble occasionally getting the 790 rear PTO lever to engage fully? Sometimes mine either only partially raises and I have to let it down and try again, or sometimes there is a slight gear grinding noise as I lift it into position to engage the PTO. Other times it lifts into place without any problem at all.<br>
<br>
If the level is sticking, sometimes the solution I've found is to let the level back down, completely release the clutch (transmission in neutral), and then depress the clutch all the way down again. Does is sound fairly normal to anyone? Anything else I can try?

I am seriously considering buying with the Ford Superduty w/the 6.0 diesel or the Chevy HD with the Duramax. In ten words or less, which would our experts on this boards recommend and why? Also, which is going to get me better fuel mileage (and about what can I expect?)??<br>

Any help would be greatly appreciated! Thanks!

I don't know about the 430 loader; however, the 419 loader on my 790 will also drift down over time. According to my JD dealer, this drifting is perfectly normal with the types of valves that JD is now using. Anyone else experienced this?

Can anyone explain to me what Deere has been doing with the 790? The older 790s had the 3NTE84 engine which produced somewhere between 27-30 hp (depending upon what numbers you believe). However, I've discovered that the new 790 I purchased a few months ago has a smaller 3NTE82 engine. Meanwhile, the Deere website says that the 790 has the 3NTE84 engine. <br>
<br>
How did I end up with a tractor that has a smaller engine and less horsepower than advertised?? My dealer has had no explanation and it seems like I purchased a tractor with the expectation of a certain horsepower and got something less. (Unfortunately, I didn't understand that the 3NTE82 really was a smaller engine until just recently.)<br>

For the record, I was using the tractor just to hold one end of the light while I was up on a ladder screwing the other end into the ceiling. I wasn't in the bucket...honest! Also, the engine was turned-off so I wouldn't gas myself in the garage.

I also noticed that the loader bleeds down when I'm out cutting the grass, and I have to tweak it up again. So, the bleeding does not seem to have anything to do with whether the engine is running or not...

I purchased a new 790 (4WD) a few months ago for similar reasons. I also like the gear transmission, though most guys prefer the hydro (which is nice, but extra, extra pricey). However, I chose a non-Deere brand mower because I wanted one with rear discharge so I approach things from either side.

From everything I know, the 790 is a fantastic, nearly bulletproof, no B.S. tractor. However, if you want lots of extra bells and whistles, then you will have to spend quite a bit more for an equivalent 4010 series tractor.

FYI: Here is the information I received from Deere:

"Thank you for contacting our website.
Here are the specifications from the latest operator's manual for the 790:
Gross HP at 2600 rpm = 26.2
PTO HP =23.6 estimated.
The 419 loader lift capacity is as you see in the specifications section of your owners manual for the loader and it is less than the 70 loader as you have indicated."

I find it disturbing that Deere could have produced a new model year tractor and replacement FEL with less capability than the older style (assuming that this message actually confirms what's printed in the manuals). Does this make sense to anyone??
