B7800 vs B2910

[dieseldom]

aside from the some of the obvious differences in workings of each machine are they basically the same running gear package?

thanks,

Yes. The 2910 has the premium features that I found a necessity. Most important of them is Position Control of the 3PH. Next one would be the lower link adjustments. That make it much easier to hook up 3PH attachments. All 2910's had a mid PTO. But not all B7800's have it.

 

[dieseldom]

well it makes some sense now. but when I first started out, making sense of the Kubota lineup was a bit confusing is Kubota in the middle of a lineup overhaul?

 

[ronjhall]

I do not think they are. The B3030 is replacement for the B2910. It has been around since 2005.

 

[dieseldom]

which one has been around since 2005? the 2910 or the 3030.
i have brochures on the B2320/2620/2920 and seperately for the
B7800/2630/3030.

the model numbering system used is somewhat confusing. could it be that way by design??

The B7800, B2630, and B3030 are all the same chasis size, and have very similar running gear. Some things like steering are different between the B7800 , and the others mentioned. The B7800 is the same tractor as the B2910 minus the deluxe items.... 3pt hitch, position control, better seat, etc. The running gear is the same in both.

thanks Chuck! i have eyes on a few 2910's in my area. i was initially looking only at the 7800. can you elaborate a bit on steering differences between these units. also, i see Kubota specs Hyd outputs independently between steering/remote. can it be assumed if unit is motionless the dual output pump will deliver combined output to remote(s) or is there some sort of valving system inhibiting this combination?

sorry for all the ?'s i'm a newbie

B2910 came out in 2000, B7800 in 2002 and B3030 came out in 2005.
The two output pumps are 2 pumps stacked on each other. They do not combine when not using power steering.
Big difference between B2910 model and B3030 tractors is hydraulic PTO engagement. B3030 is a little higher off ground to allow for the 403 FEL to work.

The steering on both the B2910, and B7800 is "power steering" while the steering on the B3030 is "Hydrostatic" meaning that there are actual hydraulic cylinders going to the wheels that do the turning. Both work just fine, and both have a light feel even with a full loader bucket. I actually think the older style on the B2910/B7800 is a little better in the woods, and brush cutting, etc. because there are no rubber boots to get torn, and no small diameter piston rods to bend. Others may have different views, and I am certainly no expert on this subject.

 

[dieseldom]

i am certainly getting an education! thanks to you both for the great info. i may have gotten around to learning of these differences myself but i need a machine fairly soon and that leaves me with little time. BB's such as TBN are oh so valuable.

thanks

I have been told-but don't know why-the B3030 has a slightly better transmission then the B7800.
If I were to do it again I would pay the extra and get the B3030. I still love my B7800 and have no plans to get rid of it.

I see your point about the potential for more damage on the B3030, but there is a sheet metal guard that protect the piston and the rubber boot, so I think
the risk for damage is low.

If you were to sit and operate both units, you'd be hard pressed to figure the differences mechanically. Ergonomics on the other hand is where, IMHO, most choices fall.

 

[Taiser]

Rubber is still rubber and it will eventually deteriate/dry rot etc, but it will take a long time. IF you are doing a lot of bush work (like I am) then you will eventually damage the boots. So far on mine (b7800), while clearing about 4 acres of heavy bush I've popped off the fuel filter the coolant petcock and both taillights and I've had branches and trunks go to places that still make me scratch my head, but we are talking major grubbing here. No way do I think I'd have intact boots if I was driving a 3030. Something to think about depending on your applications. The B7800 has a mean (beefy) front end, perfect for tearing through the bushes! But I'd still love a 3030 after my major heavy bush work is done!

I had forgotten that..... some other models don't have that guard.

question about HP on th B2910. i've have seen listings for B2910 with 29 HP and 30 HP. was there an option for both engines/horsepower or are the listings incorrect?

B2910 HP is 30.

again, I am very new to tractors and determining value (appraising) of these used machines. would $11K be a good price on a 2000 2910 w/LA 402 and 320hrs? the tractor is excellent overall condition.

That should be a very good price.

 

[Ductape]

It would be a good price around here too.........
