What is the difference between B3030, B7800, B2910

[vjcunr]

All-
The more I look, the more confused I get. Not too long ago I was all set to get the L3130. Then I became fearful that it would be underpowered for its weight, and I began considering the L3430. After considering what I would use it for, I thought maybe I could step down to the B series, save some serious money, and get a tractor that could squeeze between the trees. Mostly, I'll be snowblowing, running a PTO chipper, and light materials work.
I've looked at the specs for the B2910 and B7800 and they look very similar, as does the new B3030. How does one choose between these three? Why are there three models so similar?

The B3030 is replacing the B2910. Both have options that the B7800 does not. While they all share the same engine HP, the 7800 lacks some of the "bells and whistles" of the 2910 and 3030. I'm sure the B3030 has some other improvements over the 2910 as well. One of the most significant features that the B2910 and B3030 have is position control of the 3PH. The 7800 has only the quarter inching valve.

Here is a link to Carver Equipments pages on differences between B7800 and B2910.
B3030 is replacement for B2910.
It has some added features over B2910 like cup holder and 1 more PTO HP.
403 FEL does not have a cross bar over the hood, 100 lbs increase in lift and 6" added lift. Check out B3030 specs at Kubota.com

The B3030 also has an offset mid-point PTO, which makes connecting a belly mower easier. Also the 72" mower is drive-over, and you can get a cab version of the tractor. The hood is sloped down a little more, which might give a better view ahead.

vjcunr,

I can identify with that! This attachment shows why I like having a 54" bucket over the 60".

My B2910 was ordered with a 60" bucket, but I changed to a 54" before delivery and for my needs I am totally satisfied with that size and would not want the 60".

If I had had a 60" bucket, my tractor would have gone where it is in the attached photo... /forums/images/graemlins/smile.gif If you have a lot of trees to get between/past/around the 54" is the way to go.

Enjoy the buying process! /forums/images/graemlins/smile.gif

The current RC72-27B is a drive over. The new RC72-30B will fit older model tractors with 402 FELs.

Would Position Control or Quarter-Inching Valve be better and why?

 

[vjcunr]

I too, am interesting in the difference between the positioning valve and quarter inching valve. Also, what do the extra features of the B3030 cost over the B7800?

 

[ronjhall]

Position control will return 3PH to the same adjustable (movable stop) lowered position every time 3PH is raised and lowered again. With 1/4"ing lever is held down until 3PH is where operator visually thinks it should be.
When doing landscaping with a Rake or rear blade it is advantages to return attachment to the same position every time a pass is made.
I have attached a picture of position control against lowered stop.

 

[BRAVO_WHISKEY]

The way I understand it is Position control works on a direct relationship between the 3PH control lever and the 3PH position. -The higher the lever is positioned, the higher the lift of the 3pt arms. This allows the user to lift the 3pt and return it to a determined position easier than using the quarter inching valve. The quarter inching valve has basically 3 positions - up, down, and neutral. Pull back on the lever an the 3pt comes up. Push forward and the 3pt lowers. The position of the 3pt is set by moving the valve in the direction desired and then returning the lever to neutral. You can stop the travel of the arms at any position in between full up and full down by returning the lever to neutral position. You can move the arms in small increments, but it is a little harder to get the arms back to a predetermined position as quickly as with the position control.
