Product review (3 stars): Does not fit Kabota tractor B7800
It is a shame it won't fit the B7800 because it needs a seat redesign badly. But there is no way this is designed to fit this tractor. I considered trying to make it fit someway but decided against it for safety issues. Since the seat does not have any metal in it, I think it would be a real safety hazard in the event of a rollover.

If the manufacturer would make a seat for the B7800 I'd be glad to try it and I know I'm not the only one. Everyone on the tractor blogs that have the Kabota-manufactured seat for the B7800 detests it and it's stupid downward slope.

I don't see anything wrong with the seat other than it does not fit the Kabota B7800.
