B7800 Purchase

[WV NATIVE]

Hey guys! I just joined the forum. I’ve got a question regarding the possible purchase of a B7800 I found.

I currently have a B7500 that I use for my small property. It’s been a great tractor but the opportunity to “upgrade” has me thinking.

If I decide to buy the 7800 would any of the parts I’ve got on my B7500 swap over? The brush guard and suitcase weights will probably be easily swapped I’d think.

I’m primarily interested in swapping over the fixed ROPS I currently have so I can fit in my garage with the canopy.

Does anyone here know if the fixed ROPS from my B7500 would swap over to the B7800?

There’s some sort of rear remote on the B7800 roll bar that the seller said he never used. Does it look like a Kubota option to you guys? What could it be used for?

I’m throwing out a picture of my B7500 just because it’s fun to show off your toys. The attached B7800 pictures are from the potential seller.

Why change out the ROPS? If you want the roof, just swap that over. It just bolts on.

The B7800 rops are too tall to fit in my garage.

They both look like nice clean tractors. Without knowing what your usage and plans may be, it makes me wonder why an upgrade doesn't include things like a loader, even more HP, etc. or perhaps even a cab. With those front weights it leads me to believe you want to do more than run around with a belly mower.

I don’t really need a loader. I’ve got a S130 skid steer I use for “loader” work.

I brush hog enough that I want the added HP of the B7800 to handle a bigger hog. The addition of a mid range is kinda a big deal to me. The B7500 low range is painfully slow for mowing but high range is too fast. The added HP with a mid range sounds like a good combo for me.

Its primary purpose will be mowing - either finish mowing or brush hogging.

That makes sense. With nearly 10 more HP and the three ranges it is a substantial move.

I had a B7500 and went to an L3200 that resulted in approx. the same improvements, but a larger frame. The L3200 handled a 6' RFM better than the B7500 handled the 5 footer.

Maybe someone with a B7800 would be kind enough to measure their ROPS for me????

The ROP appear to have the same lower mount so should be able to just swap them.

You sure that the ROPS are different? The B7800 has bigger tires and that may be the height difference.

The folding ROPS are taller than the fixed ROPS by several inches.

If swapping is not an option, you could have a weld shop shorten the top half of the B7800 ROPS. or do it yourself if you’re a competent welder.

I know just mentioning such an alternative will make some people scream, but the reality is that shortening the ropes, as long as it’s modified in a way that doesn’t affect its strength, should not degrade the safety system. At least as long as you keep the shortening within reason. If you match the B 7500 height I think you would be home free safety wise. This is a practical thought which ignores the fact that we live in a sue-happy society…

I have a B 2910 which is the same tractor as the B 7800, but has a few extra bells and whistles. I want to think, but don’t know, that the reason these particular tractors have the higher ROPS has something to do with the option to add a backhoe possibly?

Could you by any chance measure the width of your B2910 ROPS for me? Center to center where they bolt up.

Carpenter tape measure accuracy:

32 & 9/16" between uprights. Add 2 inches for center to center.

Uprights are 2x3 inch tubing, thus CC is two inches greater than spacing.

Height from ground to top of ROPS roughly 87 inches. Could be plus/minus couple inches for all I know. Eyeballed it from the ground, sitting in the grass ( the tractor not me... )

Looks like the ROPS bolts onto stubs protruding up through the fenders. So the 2x3 inch tubing would be critical if you just wanted to swap ROPS between the two tractors.

Thanks for taking the time to measure that and reply.

Unfortunately your measurements confirm what I was thinking. The B7800 has wider ROPS than the B7500.

My ROPS measure approximately 25-5/8” between the uprights.

Definitely cannot swap them.
