LPGS For Kubota B2910

rswyan · May 5, 2016

BTW, I made mention of Kubota's maximum recommended implement weights on the 3PH, which I believe are probably fairly conservative.

Here's some additional data:

Maximum Lift Force @ pins: 1655 lbs

Maximum Lift Force 24" behind pins: 1300 lbs

That's the stock rating ... but my PRV is jacked up 200 psi over stock.

I'm no expert, but I just know that my 5' land plane is all my JD 2720 wants to handle when it gets a bit of rock in it. My driveway is on a hill and with the land plane less than half-full, it's spinning all four tires trying to go uphill. I normally go downhill for that reason, but I want to drag some of the rock that washed down back up the hill. My JD is about the size of your Kubota. The JD may be just a tad heavier, and I usually leave the loader on when using the land plane for a little extra weight.

Anyway, look forward to your build!

Worked out all the hydraulic cylinder attachment points and brackets.

The tailgate cylinder is Lion 2 1/2" bore x 10" stroke 2500 psi cylinder with SAE ports. Surplus Center must have an overstock of them (200+ in inventory) and be trying to move them because they were pretty cheap ($50)

It will provide slightly greater than a 90 degree range of motion, with the present bracket geometry and attachment points.

The blade adjustment cylinder is Wolverine (Prince) 2 1/2" bore x 4" stroke 2500 psi cylinder with SAE ports. A little pricier @ $64.

With the present bracket geometry and attachment points, it will provide a blade adjustment range of roughly minus 1 1/2" (cutting edge depth below the skids ... variable, depending on exactly where on the carrier I mount the cutting edge) to a positive height over 9" above the skids (again, varies on cutting edge mounting)

There is a potential interference issue with the top of the blade and my SpeeCo Quick Hitch ... but it's fairly slight. Might see if I can fix that.

If you haven't already, trying filling the bucket on the FEL ... it'll get ya a little more traction ... wet soil or gravel works good ...

Have similar issues with our 3PH snowblower (no chains, R4's) ... always blow downhill ...

Yup, it is ... very similar machines tho' ...

Non-perspective (flat) sideview with blade up. (You can see the potential inference issue):

A perspective three-quarter view:

(Might be more like 10:00 or 11:00 ... :laughing

Last time, I decided I was going to try that next time.

Thanks for the tip!
