JD790 vs Kubota B3350

Emptypocketfarms · Feb 26, 2022

Hey guys/gals, this is my first post. I’ve creeped for a long time, but have finally felt the need to ask for everyones help. I am looking into buying a 2014 Kubota B3350, I have read all of the horror stories concerning the Tier 4 regen system. So, here is my question, this particular tractor has 500 hours on it. And i am told that the regen system has been totally replaced/rebuilt (whatever they do). I know it WAS done at the kubota dealer under warranty. Since it now has just over 500 hours on it, is it safe to assume its working correctly? Or is there a way i can manually force it to regen when i test drive it on Monday? Please make any recommendations that you think may be helpful, and ill aswer all the questions that i can.
Thanks (a ton)in advance !!!!!
Please help and advise……..

Option #2- $14k - 2004 JD 790 4x4 , with loader.
No regen on the JD THAT IM AWARE OF, JD has 700 hrs, comes with 5 foot bush hog, 4WD, 60” quick attach bucket.

Option #1 - $16k- 2014 Kubota B3350 4x4, with loader,
comes WITH gen 4 regen, 500 hours, and a grapple hook attached to the 60” quick attach front bucket as well.

please impart some wisdom on me….. lol
Help if you can. All opinions are welcome!!!

The JD790 is a solid bare bones gear tractor. Not much to go wrong if it’s been treated well and maintained. I don’t believe the transmission has any synchros, so it’s full stop to shift. The Kubota 3350 has the defective exhaust regeneration system. I would approach this one with caution. I have heard that Kubota warrants this system for life to appease customers who unfortunately bought this model, so maybe you are covered? Hopefully someone who knows more about this tractor will chime in. I will say that if the 790’s capability meets your needs and if it’s in good condition, I would lean in that direction.

There was a conversation here on TBN about the B3350 warranty being life of the machine. I presume that includes non original owners, but you should certainly confirm that.

I believe @SDT has personal experience with this machine, whereas I do not. That said, I would not remotely consider a B3350, especially at 16k. You cannot manually force a Regen without dealer software, and having them do that for you will not prove anything that I am aware of.

THe kubota has stronger hydraulics but otherwise very similar in size.

If the kubota is truly option one.....I'd check with your local dealer. The one you would go to for parts and service. And see if they indeed are gonna cover you under warranty for any regen issues that may arise in the future. If they say yes....then I wouldnt be afraid of the kubota. If they say no....based on history of issues....Id avoid that model

Is the Kubota for sale on a dealers lot? IF you’re seriously considering it maybe email the dealer and ask about the lifetime warranty so you have it in writing. Courtney at GWT would tell you to run from that Kubota model I think. Maybe email Neil at Messick‘s and ask him? I think he has a 3350 for his personal machine. He’s very respected in the Kubota community.

I believe Neil kept the B3350 for less than a year, and traded it for the newer LX3310. He admits that there were problems with the 3350, but claims he needed to be able to showcase a current model tractor on Messick's YouTube channel.

it is on a dealers lot, and i have been “told” that it does have a lifetime warranty on the regen system.

And the only reason I’m interested in the 3350 is that it seems like it would have a lower COG, i have some pretty steep land.
it seems to be (only slightly) wider and not as tall. I only need approx 35HP for my needs. However i do feel that I definitely need 4x4 and a loader, but im definitely open to other considerations. The reason i say this is because the stability of the 790 concerns me, i would definitely fill the tires and add weight on either of them tho.

I'm a Kubota guy but as far as the B3350, don't walk away......RUN.

Even if the whole emission system was replaced.....it's still a poor design on that particular engine.

Does the 790 have the option to spread wheels wider? Then add liquid fill to the rear tires.

Wider is certainly better for stability....but they wear the same size rubber near as I can tell. So if the b3350 is lower, are you giving up ground clearance and is that important?
