John Deere 790 PTO engaged kills engine

   / John Deere 790 PTO engaged kills engine #11  
On my 790 there is an override for the PTO seat switch. You flip the seat up and flip over a bent metal rod sort of thing under the seat. It's for running something like a PTO generator. I've never used it so I'm not completely sure how it works...

I knew there was an over-ride of some type, but never needed it, never looked. This has prompted me to check mine when I go down to the barn.

Looking at tractordata.com your 790 is probably one of the first John Deere 790's sold as the serial number is LV0790G29XXXX. I'd bet their information is not complete. tractorbluebook.com has 790's listed back to 1999 but no serial number information. Your 790 also has the exhaust pipe coming out of the side panel like the original 790 with the 30 HP engine. For reference, I bought my 790 new December 2007. Serial number LV0790S19XXXX.

Mine was a 2004 model with the 2nd engine (of the three used in the 790)...27 Engine and 24 PTO HP. It also had the vertical exhaust.
I thought all the 790's had the vertical exhaust...not sure about the 3005 machines though.

Hey dirt ditch. I was wondering that myself, but couldn't find any info on 2wd with numbers that low. I didn't think these machines were that new but was assuming the counter tripped over to 2xxxxx after the listed starting number for '07. Make sense they are older but now I've ordered the incorrect manuals. That stinks. Well, see what shows up and how that matches to the physical when I get home in a week.

Thanks for correcting me on the exhaust. I know the later 790's exhaust came out under the left side blowing forward of the tractor.

Well, it is possible that I am wrong on this. I would think a JD dealer would be able to look up the model year to be sure.

I think asking the dealer would be the best bet to ensure the right manual is ordered.
