kubota b7100 gear to hydrostatic

[danmorea]

Have a 1979 b7100 with loader b219 and backhoe b670 that is gear drive I wonder i buy a newer hydrostatic b7100 if my loader and backhoe will fit

Yes should hook right up, the frames are the same.

hang fire before you rushout a buy a hst 7100, they are not the same dimensions as the manual 7100 version.
the drive shaft tunnel is wider than the manual version, also the the overall lenght is more so you'll need to ensure that the loader subframe will fit the mounting points on the hst and thus the backhoe then fits onto the loader frame at the furthest point onto the loader subframe.
i had a hst and tried fitting a loader from my manual and had a heap of issues, gave up in the end, if in doubt check first , its allways best with these sort of fittments.

you'll prob be fine , but thought you should be aware that just becuase its a b7100hst its not identical as the manual version, quite a few differences to be honest.

good luck.

just becuase its a b7100hst its not identical as the manual version

I have no personal knowledge of this, but I've been told the HST is longer. You might have issues with the B670 subframe rails being too short.

It is safe to assume that the two versions have different dimensions, and warrant checking into before dropping the money.

its the hst gearbox that accounts for the extra lenght, and we are not talking a few mm either. this will be the biggest issue as your loader side rails will not be long enough to reach the rear axle mounting points in the same way as on your current manual 7100, also becuase the drive shaft tunnel assembly is wider to accommadate the hst pump etc and the associated directional linkages, you may find the subframe mounting plates are not positioned wide enough to mount to the tunnel sides, unless they are adjustable but most are welded to the cross member and would need cutting off and refitting to suit the wider hst tunnel.

best advice would be to a tape measure out and compare dimensions.

So I stand corrected I thought they were the same.

I ran the #'s that you gave for the loader and back hoe, Those #'s don't match up to the newer B7100, so they may not work.

The Newer B7100HST-D takes Loader #B1630C, and Backhoe #B4672

I will run into problems for older hydro from 1980s newer 1990s or all years? For my work i have to change gears a lot -it makes me tired

 

[North Idaho Wolfman]

What B7100 are you looking to get, old or new?

Any year/model hydro that i could use my loader and backhoe

 

[Big Kahuna]

Yes, a B219 loader will fit a HST 7100 and this was the first loader they used on them, they had frame extentions to get to the rear end mounting, about 6 inches, thats about the length difference from gear to hydro, I personally have done this, IT BOLTS RIGHT ON. They are the same width on the frame, just the hydro is longer by 6 inches, I feel the back hoe would go right on also, if the brackets go past the rear end then you'll need to make extensions.

Big K , is there any chance your loader is a revised version, i had a bog standard unmodified 219 and there was no way it fitted my hst, fine on my manual 7100, but no go on the hst.
possibly a revision somehwere in subframe fabriactions .

When I blasted the cylinders, date codes were October 1979 on 3 and 1 January 1980, the tractor was a 1982 model. ? The donor tractor was a 1980 B7100 HST, went right off and right on.
