Backhoe Kubota BL4690b backhoe mast set up for a B7800

[timothy82375]

I have a B7800 that I'm trying to mount a BL4690 hoe on. The hoe came off of an L series tractor, so the top mast is different. I was going to cut and drill the mast bars to fit to my tractor. My question is: does anybody have any measurements of how long the top mast bars are and where the holes would be to fit a B series? better yet, is anybody maybe able to trace out their parts and get them to me somehow? even better, does anyone have a used top mast to fit a B series to the backhoe that they want to sell? Any help would be greatly appreciated!

The replacement for the top link should hold the backhoe in a vertical position. It should not be leaning.

You should be able to reconfigure the mast to fit the 2910 using the parts already there without any drilling. I know that's the case with the 4690A, and I presume also holds for the B.

Do you have the manual for the BH? That's where it's spelled out for the A.

If you want to send me a private message with your email, I'll email you the 4690A manual pages - it might provide a hint.
