B-2910 vs B2710

[W5FL]

Rat,

I have a 1000# boxblade. That would be a pretty good test since it carries about 3000# of dirt when full and dropping 1000# a few inches at at time is pretty revealing as to the amount of weight a tractor is intended to carry.

My rear blade only weighs 650# and is 8 ft and rated 100HP. Kubota only rates an M6800 for a 7 ft rear blade. I run it at idle knowing if you hit an immovable object (big rock), something is going to break or tear something else up. The tractor is going to just keep pulling.

I think Kubota rates very carefully the implements that are compatable with the tractor and the corresponding weights of these implements to take into account most normal operating conditions.

With my 45HP Massey on a 6 ft mower, I could get into heavy grass and have to downshift. With the 68HP Kubota - can't tell that the mower is there. Bumps are the main thing limiting speed of cutting.

We all went through a lot of confusing specifications when buying a tractor. I think the marketing types over rule the engineers and use the specifications as a marketing gimmick instead of a realistic measure of what the equipment is designed to do. Always liked to find the service manager and ask him what were the 3 biggest warranty complaints he had. Sometimes very interesting comments. Also fun to go look in the shop and see what they were working on (or not working on).

Rat,

Hope your neighbor sends you the bill when things start leaking!

If you just take a minute, with an OPEN mind to look at the rear ends of the two machines, you can SEE the difference for yourself...which one is built stronger?!?

As far as specs go, yes, I assume they are somewhat accurate and simple observations show it.

But when you buy, you might not want to care what the hydraulic flow is, or what the amps of the alternator are, or if the headlights are useable or not, or what the 3 pt is rated at, or turning radius, etc. But you obviously have way more experience than me on a tractor, seriously, so maybe the more experience you have, the specs don't mean anything? I don't know.

Jim, the really great things about hydraulics is the durability that is inherent in the design. Typical use of hydraulics, which tractors certainly come under is very difficult to damage. It will either lift it or it won't. Attempting to lift a 20 ton rock does no more harm to your hydraulics then lifting a 1000lb rock. Its all about pressure and the fact that the pump produces "X" amount and the unloader makes sure that the pressure does not exceed the designed limits. I must admit Jim, that the little B Kubota could not move my mower and use it in any practical way, I guess I was testing its limits which I did not reach. As far as rear ends go, I'm not so sure I understand that. Axle size means little if one is cast and the other forged. 4130 steel is much stronger then standard mild steel. There are far to many variables here to deal with or really care about unless the said tractor is experiencing problems. I really have no interest here except to say that unless Kubotas B series are having problems with the axles snapping off, then they are probably quite adequate. As far as open minds are concerned, some folks who think they have open minds are some of the most closed minded people I have encountered. Others have opened their minds so far their brains fell out, I'm sure you have heard of people like this, people who believe singing about raping girls and killing cops is OK and then have the gall to think that anybody who doesn't agree with their views is a closed minded, judgmental bigot. I like to think I fall into the category of having an opened mind. It really isn't for me to determine though, I have to leave that up to others. And Oscar Wilde is quite right, one look up at the stars at night and its quite easy to get lost and realize just how insignificant we are. Again Jim, hope your having a blast on the Mighty TC 18, I'm so glad you and your wife are enjoying it and the summer hopefully you have off. Take Care... Rat...

I stopped by my dealer's place this morning and took a closer look at a new B2910, and it appears to me that the lower links would be interchangeable with the ones on the B2710, so I think any 2710 owners who want the telescoping lower links and/or the new style adjustable right lift rod would just have to spend the money to buy them and only take a few minutes to change them out. I didn't ask about the price, though.

But you will. /w3tcompact/icons/smile.gif

Then post it for all to see that tractors really cost $75,000 purchased one piece at a time.

Jim, of course looking at this picture it is obvious to most that the axle is not housed. Many large agricultural tractors have used this axle/transmission differential arraingment. It takes a beefy connection at the axle to transmission junction to accomplish this. That axle is most likely much thicker then yours since it is not housed and carried by outer bearings supported by those carrier bearings. I can also assure you that the axle is made of a much tuffer high carbon steel to deal with the lateral and torque loads it will encounter. Rat...

I was just reading these old posts. I will be taking delivery of my new 2910 later this week. What everyone has missed is the reason why Kubota exposes the axle in this fashion. They do this to allow you to adjust the track width of the machine. You can adjust the rear wheels out to get greater stability or narrow to fit in an orchard or something. While I looked at green and blue, and both are fine machines, I chose the orange for the price,performance, and overall value.

I don't know how you can adjust the tread on the rear of a B2910. The hub is part of the axle and does not move. You cannot turn the wheels, they will hit the fenders. They are so close to the fenders, you will be lucky to get by with chains. The only way to move the wheels is to use spacers.

A lot of tractors ARE designed so you can move the wheels and hubs in or out on the axle, but I don't think you'll find that to be the case with you B2910. At least there's no adjustment on my B2710.

Your Right,
I confused the 2910 with the 2410. Sorry, I stand corrected. I have spent way too many hours reading tractor specs and it's become a jumble.... I can tell you I have pulled the axles on a 1 ton pickup and they we're smaller than the 2910 axles. I think you'd be hard pressed to break an axle on that machine.
